Graduate students, alaa a. alkhateeb-untreated dental disease and lung transplant waitlist evaluation time for individuals with cystic fibrosis.

Alaa A. Alkhatee, MSa, Erika D. Lease, MDb, Lloyd Mancl, PhDa, Donald L. Chi, DDS, PhDa UW Department of Oral Health Sciences

Background: Dental clearance is typically part of the evaluation process prior to placement on the lung transplant waiting list. Individuals with cystic fibrosis (CF) are thought to be at low risk for dental disease. We hypothesized that individuals with CF in need of lung transplantation would have lower dental disease prevalence and shorter waitlist evaluation time than individuals with non-CF lung diseases.

Methods: We analyzed electronic health record data for individuals who received a lung transplant between 2011 and 2017 at the University of Washington (Seattle, WA, U.S.A.) (N=280). We defined the presence of untreated dental disease using data from dental clearance forms. An individual was considered to have untreated dental disease if they had an oral infection or needed major dental treatment at time of initial dental evaluation. Waitlist evaluation time was defined as the time, in days, from the initial evaluation by a transplant pulmonologist to placement on the lung transplant waiting list. We used logistic and linear regression models for hypothesis testing.

Results: The prevalence of untreated dental disease did not differ by CF status (CF 27.7% vs. non-CF 27.6%; 95%CI: – 0.14, 0.14; P=0.99). There was no difference in waitlist evaluation time for transplant recipients by CF status (Geometric mean in days [GM]: CF 154 vs. non-CF 179; P=0.78). Differences in the two study outcomes remained insignificant after adjusting for age, sex, smoking status, and lung function.

Conclusions: Contradictory to the CF dental health paradigm, our results indicate no difference in the prevalence of untreated dental disease or in waitlist evaluation time by CF status. These findings provide further evidence that individuals with CF are not at low risk for dental disease. These findings are particularly concerning in the context of increased survival of individuals with CF, which makes it critical to ensure life-long optimal oral health.

Elise Ellingsen-Determining the differentiation pathway of N-acetyl cysteine treated SCAP

Elise Ellingsen DDS, Avina Paranjpe BDS, MS, MSD, PhD. UW Department of Oral Health Sciences

Regenerative endodontic procedures (REPs) are an important component in the treatment plan for immature teeth with necrotic pulps. Stem cells of the apical papilla (SCAP) are vital for successful regeneration of the dental pulp. Previous studies have shown N-acetyl cysteine (NAC) aids in the differentiation of SCAP making them more resistant to apoptosis. However, the pathway of cell survival and differentiation is still unknown. Hence, the aim of this study was to evaluate the effects of NAC on the survival and differentiation gene expression of SCAP.

Human SCAP were cultured and exposed to either NAC for 24 hours, non-treated (negative control) and Dexamethasone (positive control). RNA was extracted from the cells. RNA was reverse transcribed to cDNA. The cDNA was analyzed using TaqMan Array Human Signal Transduction Pathway Fast plates and TaqMan Array Human Osteogenesis Pathway Fast plates. The plates were analyzed using Real time-PCR. Data were analyzed using a one-way analysis of variance (ANOVA).

Real time-PCR analysis showed SCAP pre-treated with NAC had upregulation of anti-apoptotic genes (BCL2, BCL12L1), genes promoting DNA synthesis (CDKN1A, CCND1), and genes promoting cell adhesion (FN1) and cell proliferation/differentiation (FOS). There was a downregulation of genes involved with breakdown of extracellular matrix (MMP10 and MMP7) and prostaglandin synthesis (PGES2).

SCAP treated with NAC have an upregulation of pathways related to the maintenance of the cell cycle, proliferation and differentiation thereby protecting these cells. This research outlines the differentiation pathway of NAC treated SCAP suggesting that NAC could be used effectively during REPs.

Dianne Gan-Effect of air abrasion with a novel spherical abrasive on zirconia surface

Dianne Gan, DMD,a Muhammad Naeem Iqbal MSc,b Qianhui Xu DMD,c Zhijian Shen PhD,b Van Ramos, Jr, DDS,a and Kwok-Hung Chung, DDS, MS, PhDa UW Department of Restorative Dentistry

Background: This in vitro study was to evaluate the shear bond strength of resin cement to yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) when using zirconia-alumina composite (ZAC) particles to conduct airborne-particle abrasion.

Materials and Methods: 160 zirconia disks (4.0 mm x 6.6 mm) were fabricated from 4 commercially available zirconia blanks using computer-aided manufacturing technology. These were further divided into four surface treatment groups: as-sintered controls (ZR0), alumina airborne-particle abrasion (ABC), air abrasion with ZAC particle at 0.2MPa (2ZA), and air abrasion with ZAC particle at 0.4MPa (4ZA). Surface roughness (Ra) and area roughness (Sa) of specimens from each group were measured. Following the application of an adhesive (Scotchbond Universal, 3M ESPE), resin cement (RelyX Ultimate, 3M ESPE) buttons (4.0 mm x 6.6 mm) were fabricated for shear bond test conducted using a universal testing machine (n=10). ANOVA, Tukey HSD tests, and regression analysis were used for data analysis at α=.05. Scanning electron microscopy (SEM) was used to observe changes of the zirconia surface and failure modes of each group.

Results: The mean of Ra and Sa values ranged from 0.27μm to 0.74μm and 0.48μm to 1.48μm, respectively. The mean ±SD bond force values ranged from 272.6 ±41.4 N to 686.7 ±152.8 N. Statistically significant higher shear bond force values were obtained using airborne-particle abrasion than the controls (P < 0.05). No significant differences were found among any of the air abrasion treatment groups (P > 0.05). SEM observation revealed differences between the zirconia surfaces air-abraded with alumina versus the ZAC particle. The spherical ZAC particles create micro-craters on the zirconia surface

Conclusions: Surface treatment of zirconia with sharp-edged alumina or the spherical ZAC abrasives improved the bonding strength between zirconia and resin cement.

There are no statistically significant differences in shear bond force values between airborne-particle abrasion surface treatment groups.

Hakan Gem-FBXW7 Loss May Predict Palbociclib Resistance in HPV-Negative HNSCC

Gem H1,2, Diab A2, Swanger J2, Welcker M2, Clurman B2 UW Department of Oral Health Sciences

Introduction: Head and neck squamous cell carcinoma (HNSCC) represents the sixth most common cancer worldwide. HPV-negative HNSCC is particularly aggressive due to certain alterations in cell cycle genes. Specifically, deregulation of the G1/S checkpoint commonly occurs with the amplification of CCND1 and deletion of CDKN2A. This genomic profile is characteristic of many HPV-negative HNSCCs, and it makes them a good candidate for the targeted therapy palbociclib, a selective CDK4/6 inhibitor, to restore the G1/S checkpoint. While this drug has shown promise in preclinical HNSCC models, innate and acquired resistance during clinical trials have emerged as serious problems. The objectives of this study are to understand mechanisms of resistance related to CCNE1 up-regulation and to examine the role of FBXW7 deletion, an E3-ubiquitin ligase that regulates CCNE1 activity.

Methods: We used CRISPR technology to knockout FBXW7 in a CCND1 amplified, CDKN2A deleted, HNSCC cell line called FaDu. Using EdU incorporation and flow cytometry, we examined cell cycle dynamics of wild-type and FBXW7 knockout FaDu cells in response to palbociclib. We also used in vitro kinase assays to correlate CCNE1 hyperactivity to drug response.

Results: We showed that FBXW7 knockout confers partial resistance to palbociclib in cells that were previously sensitive. Furthermore, we showed that CCNE1 is the likely downstream mediator of this phenotype as its hyperactivity in FBXW7 knockout cells correlates with resistance.

Conclusion: By demonstrating partial resistance in FBXW7 knockout cells, we revealed a novel biomarker to palbociclib response in a HNSCC cell line. As the application of this targeted therapy expands into treatment regimens for HNSCC, predicting tumor response through biomarker testing will be an important step for successful treatment. By characterizing a resistance mechanism linked to FBXW7 deletion, we hope our data can inform the appropriate use of palbociclib in patients who will be responsive to this drug.

Melinda Lee-Effects of Cold on Vortex Blue and ProTaper Universal NiTi Rotary Files

Melinda Lee DMD, Avina Paranjpe BDS, MS, MSD, PhD UW Department of Endodontics

It is a common practice for clinicians to pre-bend a rotary file and spray it with Endo-Ice (1,1,1,2 tetrafluoroethane)(TFE). TFE helps to maintain this bend and facilitates file placement into the canal. Many previous studies have investigated various properties of NiTi rotary files. However, there are limited studies that have demonstrated the effects of cold on cyclic fatigue resistance of NiTi files. Hence, the aim of this study is to investigate the effects of TFE on cyclic fatigue resistance in two different file systems.

Vortex Blue (VB) 20/0.04 files and ProTaper Universal (PTU) F1 files were used. The files were sprayed with TFE for 3 seconds and inserted into plastic blocks with a 45° curve and operated per manufacturer’s instructions until failure. Control group files were not exposed to cold. Number of cycles to failure (NCF) was calculated by multiplying time (in minutes) until failure by RPM. The results were analyzed using Student t-test.

The results demonstrated that both the VB group and the PTU group exposed to cold had significantly lower NCF compared to their respective control groups.

This research demonstrates that exposing files to cold could dramatically affect the cyclic fatigue resistance of NiTi files. Hence, clinicians should be cautious about the use of TFE on NiTi files for instrumentation.

Shivani Suvarna-Effect of fiber reinforcement on the flexural strength of transitional implant supported fixed dental prosthesis

Shivani Suvarna, BDS; Armand Bedrossian, DDS, MDS; Van Ramos, Jr. DDS, FACP; Kwok-Hung Chung, DDS, PhD, FADM UW Department of Restorative Dentistry

Purpose . The aim of this in vitro study was to assess the effectiveness of using fiber reinforcement to enhance the flexural strength of the transitional implant-supported fixed dental prosthesis (TISFDP).

Material and Methods . 140 acrylate denture resin plates (64x12x5mm) with two holes, 7mm in diameter were fabricated using heat-polymerized (Lucitone-199) and CAD/CAM prepolymerized (AvaDent) materials to simulate a chair-side fabrication of the TISFDP. Specimens were divided into 7 groups (n=10) according to the airborne-particle abrasion of titanium cylinder (Straumann) surface and locations of fiber reinforcement ribbons (Ribbond-ULTRA); no cylinder surface abrasion and no fiber addition specimens were controls. The prosthetic screws were hand-tightened on a customized-fixture with analogs. Specimens were picked up using a 50:50 mix of chemically polymerized resin (QYK; Holmes) and repair resin (Dentsply). All specimens were stored in a water bath at 37°C for 24-hours before the four-point bending test (ASTM standard-D6272) conducted using a universal testing machine at a cross-head speed of 1mm/min. Maximum failure load values were recorded and analyzed with 2-way ANOVA and Tukey tests at α=0.05.

Results . The flexural strength values obtained ranged from 55.4±8.3MPa to 140.9±15.4MPa. The flexural strength decreased significantly when fiber was attached on the titanium cylinder surface (p<0.05). There were no statistically significant differences in flexural strength values between specimens with and without titanium cylinder surface abrasion (p>0.05). Statistically significant improvement in flexural strengths were observed in specimens with fibers added around the repair holes (p<0.05) buccally and lingually, combined with some fixation screw fractures before catastrophic failure of specimens.

Conclusions . Fiber reinforcement significantly improved the flexural strength of denture base resins only if added around the repair holes on the tension side at the site of initiation of crack propagation. Even when the specimens underwent catastrophic failure, the segments remained attached to each other with the fiber.

Daniel hovander-optical coherence tomography evaluation of deep dentin crack removal techniques.

Hovander D, Sadr A UW Department of Restorative Dentistry

Objectives: The aging and mastication stresses induce microcracks in the dental hard tissues, potentially leading to tooth fracture. There are currently no standard clinical procedures for observation and removal of these cracks. This in vitro study aimed to use optical coherence tomography (OCT) for non-invasive evaluation of the effectiveness of current clinical techniques to remove deep coronal dentin cracks.

Methods: Standard dentin cracks were induced on the pulpal floor human posterior teeth (n=40) using a diamond disc, resembling cracks extending from marginal ridges. The specimens were randomly assigned to 5 treatment groups to remove the cracks; I) #1156 bur, II) ½ round carbide bur, III) airborne particle abrasion, IV) #2 steel bur, and V) #8847 diamond bur. Before and after the crack removal, OCT scans were collected. 3D image registration was performed to analyze the amount of dentin removed and the dimensions of cracks initiated and/or propagated in each treatment group. Data were statistically analyzed at a significance level of 0.05.

Results : Dimensions of the removed dentin structure as a result of crack treatment were the largest in the particle abrasion group exhibited by the average removal depth and width of 1,124 and 1,017 µm, respectively which was significantly different from all bur groups (Man-Whitney, p<0.005). On the other hand, particle abrasion resulted in smallest crack propagation in each dimension, which was significantly different from all bur groups (Man-Whitney, p<0.01). All burs resulted in a degree of crack formation and there was no difference in crack dimensions among bur groups (p>0.05).

Conclusion: Mechanical removal of dentin cracks by conventional clinical technique using a dental bur leads to formation and propagation of the crack. Particle abrasion is a preferred technique in terms of preventing crack propagation while the amount of tissue removed may be more difficult to control than burs.

Isabelle Cassie Hwang-Effect of PDL Fiber on Force-Strain During Occlusal Loading

Isabelle Hwang1, Leigh Armijo2, Lloyd Mancl1, Tracy Popowics1 UW Department of Oral Health Sciences

Objectives : Understanding how the fluid and fibrous components of periodontal ligament (PDL) contribute to the transmission of stress to the alveolar bone during mastication is important to understanding orthodontic tooth movement. It is the goal of this study to compare the strain and force required to displace a swine incisor by 0.5 mm between the intact PDL and reduced-fiber PDL, and between different age groups.

Methods : The mandibles of 5 younger pigs and 5 older juvenile pigs were collected, and a subset of the central incisors were used (nyounger=9, nolder=7). A material testing machine (MTS) and in-fiber Bragg grating sensors (FBG) placed within the PDL were used to measure strain induced by a compressive load to 0.5mm over 15 repetitions. Incisors were tested in saline with intact PDL fibers and with fiber reduction (fiberotomy/collagenase treatment). Incisors run under both conditions (11) and run under one condition (5) resulted in 27 trials.

Results : We discovered that the PDL space develops more strain when PDL fibers are fully intact vs. reduced (median difference -9.6; 95% CI [-44.2, -4.1] and that the intact PDL fatigues over time (p-value<0.0001). Both younger (p-value<.0001) and older pigs (p-value = 0.023) showed time dependent reduction in peak force and this reduction may be greater in the PDL’s of younger pigs.

Conclusion : Our findings propound that the fibrous component of the PDL is important to maintaining the viscoelasticity of PDL and is essential to its function. We attribute the finding of PDL fatigue to the stress-relaxation of the PDL and theorize that age group differences in PDL fatigue may be the result of differences in PDL fiber composition or density, a direction of potential future research.

Timothy Liu-Identifying Dental Students’ Wellness Program Preferences

Liu TC, Randall CL UW Department of Oral Health Sciences

Objectives : Dental students experience disproportionately high rates of stress, anxiety, and depression. However, little research has focused on how dental education programs can address student wellness. The overall objective of this project was to understand dental students’ perceptions about mental health and their preferences for wellness programming.

Methods : This qualitative study involved focus group interviews with current second-, third-, and fourth-year dental students (N=20) from a single U.S. dental school. We developed a study-specific semi-structured interview guide probing school-related influences on mental health, wellness practices students already use or want to learn, and preferences for future wellness initiatives. The interviews were recorded, transcribed, verified for accuracy, and coded using inductive content analysis.

Results : Participants described two types of institution-specific influences on mental health: structural and cultural. They frequently noted that relationships with those from their own class, and those from other classes and with faculty, promote a culture of wellness within the dental school. Three types of currently used wellness practices were endorsed: independent, those involving others, and those involving university resources. Participants believed the school should do more—structurally and operationally—to promote wellness. Interest in wellness-related initiatives was high, and strongest for experiential (versus didactic) programming outside of the classroom. Participants believed such initiatives should facilitate breaks, relaxation, socialization, opportunities for mentorship/support, and/or fun. Among others described by participants, factors to consider for the successful implementation of wellness-related programs included regular (versus one-off) frequency, inter-class involvement, pairing with existing social events, and planning by administrators (versus student groups).

Conclusion : Dental students prefer experiential wellness programs organized by the school and offer considerations for program development and potential operational and cultural changes to improve wellness. The findings of this first study identifying student perspectives about wellness initiative targets and preferences can be used to inform their future development.

Eric Xu-Veillonella demonstrates increased biofilm growth when exposed to titanium particles

Xu E, Daubert D, Jain S UW Department of Periodontics

Objectives : Recent evidence suggests that the presence of titanium particles sloughed off from dental titanium implants is significantly associated with both peri-implantitis and an increase in the population of Veillonella species in subgingival plaque. We aim to begin investigation of this relationship by determining, in vitro, if the presence of titanium particles alters the growth rate or the immune stimulating potential of V. parvula.

Methods : Veillonella parvula, Streptococcus gordonii, and Porphyromonas gingivalis were grown separately in 96-well plates, either alone or with titanium particles of varying concentrations for 48 h. Titanium particles were commercially bought and suspended in water or scaled from commercially available pure titanium disks using an ultrasonic scaler. Single-species biofilm growth was quantified using a crystal violet assay. To determine changes in the immune stimulating potential of V. parvula, HEK293 cells grown in 96-well plates were exposed to media or V. parvula, with or without titanium particles, and the TLR4 response was measured 18 h to 20 h later.

Results : V. parvula showed increased biofilm growth in the presence of titanium particles, with the most growth found in the wells with the most titanium particles. S. gordonii and P. gingivalis, on the other hand, did not show any differences in biofilm growth in the wells with titanium particles. There were no changes in the robust immune stimulating potential of V. parvula in the presence of titanium particles.

Conclusion : V. parvula demonstrated increased single-species biofilm growth in the presence of titanium particles. This increase in biofilm growth in response to titanium particles was specific to V. parvula in that it was not observed in S. gordonii and P. gingivalis. V. parvula does not exhibit increased TLR4 stimulation in the presence of titanium particles. This study may help inform the development of treatment strategies for peri-implantitis.

Kevin Xu-Investigating Possible Titanate Formation And Antimicrobial Properties of Gold-Titanium Bilayer

Xu K, Chan D, Pozhitkov A, Chung W, Jain S UW Department of Restorative Dentistry

Objectives : A common problem with dental implants is that they are susceptible to biofilm formation, leading to peri-implantitis. Gold-titanates are a group of compounds that hold promise as an antibacterial coating that could mitigate this issue. We aim to investigate possible formation of gold titanate compounds through measuring antibacterial activity of zirconia washers vacuum coated with layers of gold and titanium. This will be assessed through zone of inhibition assays using Porphyromonas gingivalis, as it is a bacterial species commonly associated with peri-implantitis.

Methods : 12 zirconia washers were coated under vacuum with a constant level of titanium but a varying level (light, medium, heavy) of gold. The washers themselves had sections that were coated with gold, titanium, and both. Porphyromonas gingivalis was grown from frozen stock before inoculating into liquid media. Media containing P. gingivalis was spread plated on TYHK plates, and washers were placed in the middle (N=3). Plates were incubated for 5 days under anerobic conditions. Plates were analyzed with photometric analysis to measure zones of inhibition.

Results : The only coating group that had significant zones of inhibition as compared the control bare washer was the light gold coating group (p<.05, two-sided t-tests). There was no significant difference between zones of inhibition for sections of washers coated with gold only, titanium only, and both gold and titanium (p<.05, two factor ANOVA).

Conclusion : A lighter gold coating over titanium causes a statistically significant zone of inhibition while a heavier coating has minimal effect on the growth of P. gingivalis. Furthermore, it does not seem that gold and titanium together have greater antibacterial properties than each by themselves. These observations go against our initial hypotheses since possible titanate formation should be supported by a mixture of gold and titanium. Further studies should be done to elucidate these phenomena.

Asher chiu-fatigue loading of lithium disilicate crowns with different axial heights.

Chiu A, Chen YW, Deng S, Steele S, An SW, Sadr A UW Department of Restorative Dentistry

Objectives : Monolithic glass-ceramic crowns have become increasingly popular because of optimal esthetics and superior mechanical strength. However, limited data exist regarding the effect of axial wall height (AWH) when factoring in adhesive cementation of crowns and bonding between tooth and lithium disilicate (LD) surfaces. The purpose of this in-vitro study was to evaluate the effect of various AWH on the debonding of LD crowns under fatigue loading.

Methods : Extracted maxillary third molars were prepared for glass-ceramic crown at 20-degrees using a customized jig. Samples were divided into four groups (0 mm, 1 mm, 3 mm, 4 mm) and scanned using the 3Shape TRIOS3 Scanner. Crowns were then designed, milled, and cemented with PANAVIA SA Cement and Clearfil Universal Bond Quick following manufacturer protocol. Samples were subjected to fatigue loading with 100N at 30-degree inclination on the functional cusp using a chewing simulator (SD Mechatronik CS-4). Number of cycles until failure and mode of failure were recorded. Debonded samples were examined under microscopy and optical coherence tomography (OCT).

Results : No tooth or crown fractures were observed during 2 months of continuous loading in this study. The 0 mm group debonded under 250,000 cycles, 1 mm group debonded after 5 million cycles, while 3 mm and 4 mm groups remained intact beyond this stage. Microscopic evaluation of debonded specimen revealed that debonding had mainly occurred at the cement and LD interface, and the majority of cement remained on the dentin surface. OCT imaging confirmed microscopy findings in all debonded samples.

Conclusions : Adhesively cemented LD crowns with a short (1 mm) AWH resisted debonding for 5 million cycles which was less than that of 3 mm (6.25 million) and 4 mm preparations; however, it could be considered as clinically acceptable. Preparation of tooth for bonded restorations should consider tooth tissue preservation over excessive reduction for optimal resistance.

Trayvon Edward Foy-A Cohort Study: Stylohyoid Complex Lengths in TMD Patients

Foy, T, Taylor, S UW Department of Oral Medicine Background: Ossification of the stylohyoid complex (SHC) is a relatively common occurrence- in people. When presenting in combination with head and neck pain and/or other symptoms, such as dizziness or difficulty swallowing, this combination of findings has been named Eagle’s Syndrome (ES).

Objectives : The present study utilized anonymized subject CBCT imaging and TMD Impact Study Questionnaires to compare the mean questionnaire response values of specific questions (relating to symptoms associated with ES) and the length of SHC’s. H0: The length of the SHC has no association with the questionnaire response value of TMD Impact Study participants.

Methods : A cohort study was conducted on 132 patients ¬¬ – these subjects were returning patients included at one site of a multi-center TMD study1. Each subject had completed a number of questionnaires and had a diagnostic CBCT image taken for TMJ assessment. This data was used for this study. Questions related to symptoms associated with ES were selected. The responses to these questions were scored (0= no, 1=yes). The length of the SHC’s were measured by two observers. Chi-squared test were used to compare the two categorical variables, mean question response value and SHC length (>25mm or <25mm). The statistical significance level was set at 0.05.

Results : It was determined that 22 (16%) of all 132 patient SHC’s were within normal limits bilaterally (<25mm) and 70 (53%) were elongated bilaterally (>25mm). Statistical analysis of responses to questions 1 (p =. 66), 2 (p= .46), 3 (p = .71) and 4 (p = .67) independently showed no significance correlation to SHC lengths (p <.05).

Conclusions : In this study, there was no association between the length of the calcified SHC and the number of positive reports of ES symptoms, in this TMD study population.

Shale Ninneman-Treatment Outcomes of Sinus Regeneration and Implant Survival Following Sinus Lifting via Lateral Window Technique

Ninneman S, Zarrabi I, Prajapati S, Daubert D, Wang I, Hsu YT UW Department of Periodontics

Background : Lateral window sinus floor elevation (LSFE) allows implant reconstruction in the posterior maxilla. The aims of this retrospective study were (1) to determine demographic or surgical factors related to Schneiderian membrane perforation (SMP) during LSFE, (2) to investigate the outcomes of implants placed in grafted sinuses.

Methods : The retrospective study was approved by the UW institutional review board. All data was retrieved from an existing database of electronic health records. Demographic and surgical-related factors at SFE were recorded. Outcome variables included the incidence of SMP during LSFE, implant survival, and prosthetic complications. Fisher’s exact test was used to compare any differences in abovementioned factors between groups with or without SMPs.

Results : Sixty-four patients (65 ±12.36 years) with a total of 82 sinuses and 110 implants placed in the grafted sinuses were included in the study. At the time of LSFE, 5 patients were diabetic and 9 patients were currents smokers. Forty-nine patients were diagnosed with periodontitis and 11 patients had gingivitis. For the surgical factors, the window of LSFE were outlined by rotary burs in 31 sinuses and piezoelectric devices in 32 sinuses, respectively, with 19 being unknown. Prophylactic antibiotics were given for 62 patients before LSFE. Twenty-one sinuses were perforated during surgery, with an incidence of 25.6%. However, none of these factors showed significant association with the incidence of SMPs. Among 110 implants placed in the grafted sinuses, 8 required additional osteotome prior to implant placement, and 2 of these were in areas of prior SMP. Eighteen implants required GBR simultaneously with implant placement, with 8 of these in areas of prior SMP. The overall implant survival rate is 97.2% with 5 prosthetic complications and 14 implant complications.

Conclusion : With the study limitations, LSFE is a reliable procedure with promising survival rates of implant placed in grafted sinus.

Mimansa cholera-mitigating global oral-health inequalities: research training programs in low- and middle-income countries.

Seminario, A.L., DeRouen, T., Cholera, M., Liu, J., Phantumvanit, P., Kemoli, A., Castillo, J. and Pitiphat, W UW Center for Pediatric Dentistry

Although oral diseases are largely preventable, they are among the most non-communicable diseases globally, and they disproportionately burden disadvantaged communities, especially within low- and middle-income nations. The COVID-19 pandemic has highlighted the social, economic, and health inequalities in our society, including the existing global oral health inequalities. There is a shortage of dentist-scientist all around the world, especially in developing countries, such as Thailand. The National Institute of Dental and Craniofacial Research (NIDCR) and Fogarty International Center (FIC), joined efforts on creating research capacity in oral health in South East Asia through the Fogarty International Center Training Program in Clinical, Public Health and Behavioral Oral Health Research for Thailand (2006 – 2016). The University of Washington (USA), Thammasat University (Thailand) and Khon Kaen University (Thailand) partnered to conduct short-, medium- and long-term training programs to build regional oral health research capabilities. Investing in research has not only impacted trainees’ career development but enhanced advancement of oral health research of South East Asia. The success of partnership calls for expanding oral health research training in other low-income countries.

Mojdeh Eftekhar-Characteristics of Periodontal Ligament in the Pig Model with Experimental Periodontitis

Eftekhar M, Lee L, Salamati A, Liu ZJ UW Department of Orthodontics

Objectives : Hypermobility, a common symptom of periodontitis, is due not only to the loss of alveolar bone, also to the associated alteration in the periodontal ligament (PDL). The present study hypothesized that the structure of the PDL Sharpey’s fibers is altered by experimental periodontitis in the young pig model.

Methods : Six three-month-old pigs were periodically inoculated with four types of periodontal bacteria, along with a ligature around the last maxillary deciduous molar for eight weeks to induce periodontitis (PG). Eight same-aged pigs served as the control group (CG). Upon euthanasia, the harvested molar blocks were sectioned coronally and stained with either hematoxylin & eosin (H&E) or Sirius Red (SR). The structures of PDL on H&E-stained images were first reviewed. Then, each adjacent SR-stained section was chosen, and the images were captured at the region close to the apex of the mesial roots under polarizing light microscopy. Sharpey’s fiber numbers in each bundle (Bundle size), total bundle numbers, the connection of the bundle to the root cementum and alveolar socket, as well as bundle angulations to the long axis of the molar, were quantified in the defined area 500μm apical to the root apex. Three images were captured and quantified in each animal by using Metavue software.

Results : Compared to the CG, the PG showed the following features: 1) less in the total bundle number and fiber numbers in each bundle; 2) more interrupted fiber bundles; 3) more oriented toward the cervical in the bundle angulation.

Conclusions : These results suggested the experimental periodontitis leads to the altered structures of PDL Sharpey’s fiber in young pigs.

Jeffrey Lee-Sugary Beverages Associated with Caries in Children with Special Needs

Lee JN, Scott JM, Chi DL UW Department of Oral Health Sciences

Dental caries is a significant public health problem for low-income children with special health care needs (CSHCN). We evaluated associations between oral health behaviors (e.g., diet, fluoride, dental care) and caries for CSHCN enrolled in Medicaid, a health insurance program for low-income populations that provides comprehensive dental coverage for children. We recruited 116 CSHCN ages 7 to 20 years from Medicaid enrollment files in Washington State. Caregivers completed a 166-item questionnaire and children received a dental screening. The outcome was dental caries, defined as total pre-cavitated, decayed, missing, or filled tooth (PDMF) surfaces. We ran log-linear regression models and generated prevalence rate ratios (PRR). The mean age of study participants was 12.4±3.1 years; 41.4% were female, and 38.8% were white. The mean PDMF surfaces was 6.4±9.4 (range: 0 to 49). Only sugar-sweetened beverage intake was significantly associated with dental caries. CSHCN who consumed >4 sugar-sweetened beverages per week were significantly more likely to have tooth decay than those who consumed no sugar-sweetened beverages (PRR: 2.58; 95% CI: 1.37, 4.85; P<0.01). Sugar-sweetened beverages are an important target for future behavioral interventions aimed at preventing dental caries in low-income CSHCN.

Xuelian (grace) huang-comparison of disinfection performance between led and conventional uvgis.

Huang X 1, Xu KA 2, Jain S 3, Chan D 1 UW Department of Restorative Dentistry

Objectives : Ultraviolet (UV) light is one of the technologies widely used for inactivating bacteria, viruses, and fungi in disinfection of surfaces. UVC irradiation (200-280 nm) is the main source of the germicidal effect. The present study was to evaluate the disinfection performance of LED and mercury lamp based conventional UV germicidal irradiation (UVGI)

Methods : Porphyromonas gingivalis was spread on the TYHK-agar plates. Plates were covered with lids lined with tin foil, except for a square window to expose the agar. Then the plates were treated by the following three commercial portable UVGI sanitizers at the wavelength of 253.7 nm for 1s, 5s, and 10s respectively. No UVC treatment and Ampicllin were used as negative and positive controls, respectively. All the plates were then incubated in an anaerobic condition for 48h. To further evaluated Brand C, stimulated saliva was spread, treated by UVC for 1s, 5s, and 10s respectively and then incubated.

Lamp Power (W) Intensity (mW/cm2) Brand A Mercury 4 3 Brand B Mercury 5 2.5 Brand C LED 80 65

Results : Brand A could kill P. gingivalis after 5s treatment, while Brand B needed 10s. Brand C with LED lamps could kill all the P. gingivalis after almost 1s. For much denser colonies from saliva, Brand C could reduce the density significantly after 1s and kill almost all the microorganisms after 5s.

Conclusions : LED UVGI is much more effective than the mercury lamp based conventional UVGI, probably due to higher power and output UV intensity.

Rachel Roston-Maxillo-Frontal Suture Histomorphology Suggests Complex Loading in Tursiops truncatus

Roston RA, Mirando AJ, McLellan WA, Pabst DA, Hilton MJ, Roth VL UW Department of Orthodontics

Sutures, the fibrous joints between bones, serve important roles in the growth and mechanics of vertebrate skulls. Based on their varying mechanical functions, sutures display different collagen fiber orientations and bone morphologies (e.g., abutting, interdigitated, beveled). While most mammal skulls, including those of humans, possess beveled and overlapping sutures, the histological structure, ontogeny, and biomechanics of these sutures are largely unknown. Cetaceans (whales and dolphins) in particular have taken bone overlap to the extreme—some sutures cover nearly the entire surface of the underlying bone—and possible functions of this extensive bone overlap in cetaceans have been widely speculated. To inform investigations of functional hypotheses for overlapping sutures, we examined the maxillo-frontal suture in neonatal and adult bottlenose dolphins (Tursiops truncatus) using CT, microCT, and histological methods. We found that in the neonates, the bony margins of the suture were smooth and the sutural fibers were oriented parallel to the bone margins. In contrast, in the adult, the maxilla and frontal were interlocked with rugose interdigitation of the bones and a complex arrangement of collagen fibers. This adult morphology suggests this suture in cetaceans, and perhaps overlapping sutures more generally, forms a strong joint that resists complex mechanical loading.

Sami Dogan-Peptide-guided biomimetic formation of structurally integrated acellular cementum-PDL interface

Dogan S, Baioumy Y, Lyu L, Yip E, Hamann J, Yucesoy DT, Fong H, Bulmus V, Sarikaya M UW Department of Restorative Dentistry

The goal of this research is to develop a biomimetic strategy to facilitate regeneration of an acellular cementum (aC)-PDL interface by forming an integrated hybrid of mineral layer functionalized with the peptides derived from the key proteins of the periodontium, which with further research, can be adapted for clinical regenerative therapeutic strategies. Four ambitious specific tasks are set forth to realize the overarching objective: (i) In vitro remineralization of demineralized cervical root dentin using shADP5, a mineralizing peptide derived from amelogenin; (ii) Functionalization of remineralized dentin surface with chimeric peptides with Hap binding and PDL cell-favorable attachment/signaling functions, identified via machine learning tools and high-throughput screening methods or designed according to sequences known in literature; (iii) Quantitative determination of preferential PDL cell attachment/proliferation and orientation, over gingival epithelial cells, on biomimetic hybrid peptide-mineral layer; and (iv) Identification of biomimetic hybrid layer yielding structurally integrated aC-PDL junction. The lab team has optimized a remineralization strategy that provided pathways to achieve several goals. Namely, functional stable remineralized layer has been formed on the surface of dentin forming continuous mineral layer that penetrates into exposed dentin tubules. This achievement is the key step in the formation of a functional cementomimetic layer towards building the PDL. The team is in the process of identifying the signaling peptides derived from relevant proteins towards the generation of structurally integrated aC-PDL interface. The presentation will give highlights of the latest developments.

Hanson Fong-Peptide-Guided Remineralization Protocols in Biomimetic Dental Care

Fong H, Yucesoy DT, Dogan S, Bulmus V, Sarikaya UW Department of Materials Science and Engineering

In convergent science approach that involves genetic engineering, biochemistry, bioinformatics, molecular biology, dental science and technology and materials sciences and engineering, we have developed a combination of highly versatile platform in which biomineralizing peptides are used for controlling tooth remineralization towards developing practical treatments of diseases with the demineralization origin. Our team has developed a platform technology based on the design of peptides from proteins that epitomize their key functions. Using amelogenin, the key protein in enamel mineralization (as well as Fetuin-A, osteopontin, OC90 and matrix-gla protein), we developed a set of Amelogenin-Derived Peptides (ADPs) with hydroxyapatite (HAp) binding and mineralization properties. In particular, using shADP5, a 15-AA long peptide, we demonstrated biomimetic restoration of human (in vitro) and rat (in vivo) enamel (incipient caries), and occlusion of (human) dentin tubules (in vitro) through remineralization. In all cases, the newly formed mineral layer was demonstrated to be structurally, chemically, and mechanically integrated into the underlying enamel and dentin tissues, the critical step to achieve functional restoration of the tooth with long-term durability. Using the protein-derived peptides we have developed formulations, such as solution, gel, lozenge, varnish, and paste as well as antimicrobial and osteointegrative biogenic coatings for implants (each in the R&D pipeline at different stages of development) and demonstrated their in vitro and in vivo efficacy using demineralized teeth. With the goal of bringing the formulations to the level of the minimum viable products, the team is currently planning to initiate human trials in the coming months, a critical step before for practical OTC and clinical implementations.

Mehmet Sarikaya-Deep Selection and Design of Protein-Derived-Peptides for Biomineralization and Signaling

Sarikaya M, Gunderman H, Hamann J, Rodriguez J, Yucesoy DT, Fong H, Dogan S UW Department of Materials Science and Engineering

Based on convergent science approach, including computational biology, bioinformatics, biochemistry, oral health science, and materials sciences, the goal of this project has been to identify functional domains within the native proteins of periodontium that are known to control mineralization and regeneration of cementum, cementum-PDL junction, and PDL tissues. Three specific tasks are set forth to realize the overarching objective: (i) Identification of domains within the known periodontium-related proteins using a ML- and bioinformatics-based algorithms which incorporate HTP experimental selection of peptides using combinatorial mutagenesis combined with next-generation sequencing; High-throughput characterization of identified peptides using custom peptide-arrays and massively parallel fluorescent cell attachment, proliferation and toxicity assays; and (iii) Iterative redesign and refinement of robust (chimeric) peptides with multiple functions through conformational and functional deep mutational scanning. Although the bench work has been restricted significantly because of the pandemic, in this Spencer project the progress has been highly unusually rapid with diverse spinoff projects with implications for future progress in many fronts in the Lab’s quest for peptide guided biomimetic dental restoration, repair, and therapeutics of for innovative oral care. In the first part of the project, the team is developing a machine learning (ML) algorithm to discover short sequences from biomineralizing and signaling molecules with a biomineralization function in dental tissues. This part of the project has focused on the identification of mineral binding and signaling domains in a variety of Hap-binding proteins, including amelogenin, as well as Fetuin-A, osteopontin, OC90 and matrix-gla protein. Once the consensus sequences with affinity to HAp are identified within proteins that undergo biomineralization, the next step is to demonstrate the relatedness of species’ proteins via looking purely at their domains, and characterizing the mineralization characteristics of chosen sequences. In parallel, the team has been optimizing the high-throughput system for biomimineralization screening studies. In the next step, the high-throughput system is focusing on generating high volume biomineralization data for assessing the effect of peptide sequences derived in Part 1 of this project on the mineral formation characteristics (rate, morphology, mineralogy, etc).

Deniz Tanil Yucesoy-Biomimetic Tooth Repair: Towards a Potent Dental Hypersensitivity Treatment

Yucesoy DT, Fong H, Hamann J, Hall E, Dogan S, Sarikaya M UW Department of Materials Science and Engineering

Dentin hypersensitivity (DH) is a common oral health condition that affects the quality of life. The exposure of dentin tubules due to demineralization is a prevalent cause of DH. Despite being a widespread ailment, no long-term solution exists to permanently address DH. Current treatments are designed to alleviate the pain by either using desensitizers or blocking tubules by secondary precipitates, which are transient due to their loose integration with dentin. Ideally, DH treatment should reproduce a mineral layer on dentin that extends into the tubules and reestablishes the structural and mechanical integrity of the tooth to achieve permanent durability. Here, we describe a biomimetic treatment that utilizes a mineralization-directing peptide, sADP5, derived from amelogenin using biochemical and bioinformatics design principles. Demineralized human mid-coronal dentin, mimicking DH, were subjected to repeated rounds of peptide-guided treatment. The structure, composition, and nanomechanical properties of the remineralized dentin is analyzed by cross-sectional scanning electron microscopy imaging, energy dispersive X-ray spectroscopy and nanomechanical testing. The occlusion of exposed dentin tubules achieved through a layer-by-layer mineralization process that formed continuous mineral layer penetrating into the tubules. The elemental analysis provided Calcium/Phosphate composition, similar to that of hydroxyapatite. The average hardness and reduced elastic modulus values for the mineral layer were significantly higher than those of the demineralized and sound human dentin. The interface between the mineral layer and the underlying dentin remained integrated after 90 days of thermal aging with no marginal separation. These results suggest that structurally robust and mechanically durable interface forms between the mineral layer and underlying dentin that can withstand long-term thermal stresses encountered in the oral environment. The remineralization procedures described herein could provide a foundation for the development of effective biomimetic oral care treatments for a wide range of demineralization-related ailments and, more specifically, a potent long-term solution for DH.

This systematic review looks at thematic trends in clinical research publications on dental implants. For this purpose, MEDLINE electronic searches as well as additional hand searches of six main journals in the field were conducted. A total of 2875 clinical studies published between 2001 and 2012 met the inclusion criteria and were subjected to statistical analysis. Hot topics in dental implant literature included immediate loading (14.3%), bone substitutes (11.6%), cross-arch full bridges (8.0%), and immediate implant placement (7.5%). A significant increase in scientific interest for immediate loading (+6.3%, p = 0.001), platform switching (+2.9%, p = 0.001), guided implant surgery (+1.9%, p = 0.011), growth factors ( p = 0.014, +1.4%), piezoelectric surgery (+1.3%, p = 0.015), and restorative materials (+0.7%, p = 0.011) was found. A declining scientific interest in onlay grafting (−0.3%, p = 0.042) was recorded. The findings regarding current clinical oral implants research tie in with better-informed consumers and increased patient demands. Our results demonstrate an increasing interest in techniques that avoid complicated procedures such as bone grafting and that reduce treatment duration.

1. Introduction

The present special issue of Dentistry Journal deals with “Advances in Implant Dentistry,” and the following keywords denote hot topics in this field: template-guided implant placement, minimally invasive techniques, short lengths and reduced implant diameters, novel bone grafting techniques, medically compromised patients, peri-implantitis treatment, immediate placement and restoration, transition from a failing dentition, CAD/CAM prosthetics, and optical intraoral impressions. As the first paper in this special issue, the following review aims to provide the background to recent trends and “hot topics” in advanced and minimally invasive oral implant treatment [ 1 ].

The concept of osseointegration of oral implants was introduced by Branemark 40 years ago and set the precedent for new knowledge in oral medicine. Since then, oral implantology has become one of the most investigated topics in dental medicine, with exponential growth in the use of implant products [ 2 ]. Data shows that the number of implants used for oral rehabilitation in the USA increased ten-fold between 1983 and 2002 and also ten-fold from 2000 to 2010 [ 3 ]. While previously the primary aim of research on oral implantology was to find ways to rehabilitate function [ 4 ], many efforts nowadays are focused on the shortening of treatment procedures, simplifying surgical techniques, and esthetic improvement [ 5 ]. It is well known that oral implantology is a prosthetically driven field with a major surgical component [ 6 ]. Therefore, the current state of the art in implant dentistry represents advances in both surgical and prosthodontic techniques [ 5 ].

Keeping pace with research development, the aim of this systematic review was to investigate contemporary issues in oral implantology research and to perform a topical trend analysis of clinical studies published in the time period from 2001 to 2012.

2. Material and Methods

2.1. search strategy.

A MEDLINE electronic literature search was conducted, limited to clinical studies on dental implants published between 2001 and 2012. The search term “dental implant,” sorted by “year of publication” was used in order to capture all relevant articles [ 7 ]. Additional hand searching was performed to examine six main journals in the field: The International Journal of Maxillofacial Implants , Journal of Oral Implantology , Clinical Oral Implant Related Research , Implant Dentistry , European Journal of Oral Implantology , and Clinical Oral Implant Research . Two reviewers independently identified all trials [ 8 ]. The PubMed search initially identified 15,695 publications, and 5048 additional results were identified by hand search. These studies were screened for their relevance based upon a threshold set [ 9 ]:

• inclusion criteria: prospective and retrospective studies, cross-sectional studies, case-control studies, case reports with at least 10 patients
• exclusion criteria: non-English publications, statistical studies, animal studies, finite element analyses, in vitro studies, review articles, and case series with fewer than 10 patients.

A total number of 3695 articles were subjected to abstract review. Where the abstract provided little information, a full text analysis was performed. Authors of potentially relevant publications, which were not available or lacked data, were contacted and asked for cooperation. Ultimately, 2875 clinical studies were identified as meeting the inclusion criteria. Our goal was to investigate how trends change over time as regards the topics examined in modern implant dentistry research. In this respect, we have determined that 31 topics were appropriate: 23 of them concerned surgical issues and 8 dealt with prosthodontic issues ( Table 1 ). First, all relevant publications were screened for the topics listed in Table 1 independently by two reviewers. Thereafter, the results were verified, and all doubtful publications were discussed before the final decision was taken.

Topics sorted by literature coverage. Absolute numbers of publications per year as well as the total percentage of all clinical papers 2001–2012 (* indicates prosthodontic topics).

2.2. Statistical Analysis

As mentioned above, 2875 publications were analyzed. In order to find statistical trends in respect to the relevant topics between 2001 and 2012, Poisson regression analysis was performed, taking the level of significance as p ≤ 0.05, using R-project statistical software version 3.1.0. This statistical test was used to model count data, which in this case was the number of publications. p -values were calculated for every topic, taking into account the relative number publications per topic from the total number of publications.

The surgical and prosthodontic topics of interest were computed as percentages of the total number of publications ( Table 1 ). Among the most covered surgical topics in the literature were immediate loading (14.3%), bone substitutes (11.6%), immediate implant placement (7.5%), simultaneous implant placement with bone augmentation (6.4%), onlay grafting (4.3%), medically compromised patients (4.0%), healing modality (3.7%), transcrestal sinus floor elevation (3.0%), flapless surgery (2.7%), socket grafting (2.6%), and guided surgery (2.4%). Immediate loading (14.3%), cross-arch implant bridges (8.0%), early loading (4.5%), and platform switching (1.7%) were ranked as the most prevalent prosthodontic issues in current oral implant research.

The surgical issues were the more prevalent topics, demonstrating an increasing rate of publications over the time in terms of mean coverage (0.53 ± 0.01) per publication ( Figure 1 ), as compared to prosthodontic issues (0.33 ± 0.05 hits). The mean coverage values were estimated based on yearly ratios: the number of prosthodontic/surgical publications per year in relation to the total number of publications per year. The significant increase in publications on surgical issues over the years was demonstrated by Poisson regression analysis ( p = 0.002).

Literature coverage of surgical (s) versus prosthodontic (p) issues: x-axis indicates year of publication, y-axis indicates the ratio of numbers of publications (surgical/prosthodontic) to the total number of publications per year.

A total of eight topics showed significant trends ( p < 0.05) over the years 2001 to 2012 ( Table 2 ). Immediate loading demonstrated the highest increase with a positive change of +6.3% and p = 0.001 ( Figure 2 a). Platform switching (+2.9%, p = 0.001) was the second topic showing a significant increase; however, only one relevant article was detected between 2001 and 2006 ( Figure 2 b). These topics were followed by guided implant surgery (+1.9%, p = 0.011), growth factors (+1.4%, p = 0.014), piezoelectric surgery (+1.3%, p = 0.015), and restorative materials (+0.7%, p = 0.011). The green line represents the percentage of the total number of publications for every year. The black trend line reveals the relationship between the year of publication (x-variable) and the percentage of the total number of publications (y-variable). Since there were no publications on platform switching between 2002 and 2005, there is a negative trend line intercept starting from 2001 ( Figure 2 b). Decreasing scientific interest and a corresponding downward trend were recorded for the topic onlay grafting (−0.3%, p = 0.042).

Trend curves (percentage out of the total number of publications per year) for ( a ) immediate loading; ( b ) platform switching; ( c ) flapless implant surgery; ( d ) guided implant surgery; ( e ) growth factors; ( f ) piezoelectric surgery; ( g )restorative materials; and ( h ) onlay grafting.

Topics demonstrating a significant increase (positive) or decrease (negative change) of scientific interest in the years 2001–2012.

4. Discussion

Comparisons of published clinical trials per year revealed a trend of increasing interest in conducting clinical trials, starting with 137 relevant articles in the year 2001 and reaching the number of 446 publications in the year 2012. However, even the total number of 3695 articles is smaller than the total number of 4655 clinical studies published between 1989 and 1999 reported by Russo et al. [ 10 ]. Given that the number of publications increased with every year, it was considered more appropriate to perform Poisson regression analysis related to percentage-based values rather than related to absolute values for all topics.

Immediate loading proved to be the most studied topic in the last decade ( Figure 2 a). This avid scientific interest can be explained by several advantages it offers, such as shortened treatment protocols, immediate rehabilitation of the function, and high patient satisfaction. Meta-analyses on single-tooth implant placement have shown encouraging results for the immediate loading protocol as a promising alternative to conventional loading, as it may be equally successful and may not significantly affect marginal bone resorption and implant success rates [ 11 , 12 , 13 ]. Another meta-analysis by Papaspyridakos et al. [ 14 ] reported that there was no significant difference between immediate, early, and conventional loading in edentulous patients with fixed prostheses, and all three protocols showed a high level of success. However, other reviewers disagree with this assessment of the unimpaired success of the immediate loading protocol. A meta-analysis of clinical studies comparing the immediate and conventional loading of single tooth implants discovered that immediate loading has a significantly higher risk of implant failure [ 15 ]. Schimmel and coworkers [ 16 ] concluded that, despite the high implant survival rates, the conventional and early loading protocols are superior to immediate loading as better documented protocols, providing better results in the first year of loading. A survey among implantologists from 16 countries all over the world stated that immediate loading was the treatment protocol most accepted by dentists in Australia and Europe [ 17 ]. Based on these controversial statements in the literature, it can be concluded that there is still a lack of well-designed RCTs concerning loading protocol [ 18 ] and immediate loading may well retain its place as a hot topic of discussion over the coming years.

The platform-switching concept arose in 1980 with the introduction of the wide diameter implants. Due to the lack of commercially available matching components for wide diameter implants, the standard-diameter abutments were used. Later, it was found that “platform-switched” implants demonstrated osseointegration with less initial crestal bone loss and were thus superior to the “platform-matched implants” [ 19 ]. However, the first introduction of this concept appeared in 2005 [ 20 ]. Radiographic observation over a period of 13 years demonstrated that platform switching resulted in little or no crestal bone loss as compared to the conventional implants, whereas marginal bone resorption of 1.5 mm on average was accepted as one of the criteria for success of the dental implant [ 21 ]. Our study shows that the increasing publication rate of clinical studies happened to coincide with the first official introduction of this concept, with a positive linear trend for this topic starting in 2005 ( Figure 2 b). Since guided surgery is performed in combination with the flapless procedure in most cases, [ 22 ] the similarity in literature coverage, illustrated in both scatter plots, does not come as a surprise ( Figure 2 c,d).

In contrast to the last decade of the 20th century, when the main progress in the field of oral implant research was made in alveolar bone resorption management to refine the different graft techniques [ 23 ], our findings show that in the 21st century there has been increasing interest in methods developed to overcome the grafting procedures and even a loss of interest in one of the most used augmentation techniques, i.e. , onlay bone grafting. It seems that dental implant scientific work is inspired more by the patient’s appraisals [ 24 ], seeking to improve minimally invasive surgical techniques [ 25 ], diminish patient morbidity, and shorten the treatment time. However, the role of industrial funding for conducting clinical studies should be taken into consideration. 32.4% of the clinical trials are supported by industry as a source of funding, which is a suitable way for companies not only to comply with safety and efficacy standards, but also to introduce their new products to the market [ 26 ]. This industry sponsorship may lead to biased reporting and pro-industry conclusions [ 27 ]. This does have the potential to reflect on ongoing trends in clinical research. In this connection for instance, the relatively innovative technique of guided implant surgery provides less painful and invasive treatment but at the same time is a more difficult and expensive procedure than conventional implant placement, demonstrating the same survival rate. However, a survey by Hof and coworkers [ 28 ] showed that the main priority for the patients when it comes to implant therapy remains the predictability of treatment success. The achievements brought about by ongoing clinical research, such as improved quality, ease of use of implant systems, as well as shorter treatment duration [ 29 ] may provide grounds for future researchers to face the challenge of preserving the perspectives of clinical implant research, and specifically, to enhance the relationship between private practice and science without involving marketing.

In order to adhere to ethical rules on explicit reporting, including also the disadvantages of any study, the researchers are obligated to report their study’s limitations. Undoubtedly, meta-analysis is the “gold standard” for performing any systematic review aiming at assessing treatment effects. Given that the variable investigated in the present study was the number of publications, the Poisson regression was selected as a statistical tool. The Poisson regression is used to model count data (in the present case this is the number of publications) and is an appropriate statistical method for predicting trends. Therefore, no methods estimating risk of bias, quality design, or heterogeneity of the studies provided by the meta-analysis were applied in this study.

A further limitation is presented by the use of only one database source. The findings in the present work are based on analysis, including studies from MEDLINE, and an additional hand search of six journals. However, the search strategy did not consider other databases such as EMBASE and the Cochrane Central Register of Controlled Trials.

In conclusion, the analysis of scientific literature on dental implants revealed several hot topics in the time period between 2001 and 2012. The most frequently covered surgical issues were bone substitutes (11.6%) and immediate implant placement, (7.5%), while the most prevalent prosthodontic topics involved immediate loading (14.3%) and cross-arch full bridges (8.0%). Given that the topics demonstrating the highest increase in interest were prosthodontic topics, i.e. , immediate loading (+6.3%) and platform switching (+2.9%), the interest in researching prosthodontic topics will most likely continue to increase.

350+ Presentation Topics That Will Appeal to Any Audience

I like building and growing simple yet powerful products for the world and the worldwide web.

Published Date : December 4, 2020

Reading Time :

A presentation can be nerve-wracking, may it be for first-timers or pros, as you must turn a critical issue into a dynamic, persuasive, and informative one. Before you enhance your oratory skills and overcome your fear of public speaking , you must brainstorm excellent, fun topics for your presentation.

When doing a presentation, you cannot start a thing without coming up with a presentation topic . It is harder to find the best subject than prepare the lecture, as you need to be specific about the topic you want to present.

Besides oratory skills and PowerPoint mastery, you need to have informative and fun topics for presentations that can influence the audience. Watch this and get more ideas about informative topics:

One of the best ways to nail a presentation is to choose the best presentation topics that fit your expertise and target audience.

How to Choose a Good Topic

Choosing the best one out of informative presentation topics can be daunting and confusing if you want to create an informative speech or lecture. Here are some considerations that you must know.

• Purpose. Deciding your goal determines what your audience will bring after your talk, especially for persuasive presentation topics. Here is a video on various topics about persuasion:

• Audience. Consider your audience’s demographic profiles and common ground when choosing presentation topics and connect them with their interests, beliefs, and social and cultural backgrounds.
• Interests. Determine what presentation topic ideas you are most passionate about and what you know the most. Interesting topics for presentation give a head start upon your research phase, ensuring a well-received discussion for the audience. Get useful guides on how to keep your audience interested in this video:

• Credibility. To convince your audience about the pieces of information that you will discuss, choosing a credible and well-backed lecture is another plus.

Tips on Turning a Boring Topic into an Engaging Presentation

You might have been feeling dejected as you had to prepare for a talk with no fun topics for presentation. It is hard to turn psychology discussions into engaging ones, knowing that this field has jargon and cases that can make your lecture dull.

What does a perfect day with the family look like?

Imagine a day filled with laughter, shared meals, and playful adventures. Waking up refreshed, a family connects over breakfast, sharing dreams and creating plans. They explore together, be it a museum visit or a quiet picnic, finding joy in nature, or friendly competition. As the sun sets, reflections filled with gratitude paint the evening, solidifying the love and connection that makes the day perfect, not for its grandeur but for the simple treasures of being together.

What do you want to be when you grow up?

When asked, “What do you want to be when you grow up?” children explore a world of possibilities. Each child has unique dreams, from doctors to astronauts, artists to veterinarians. Their dreams may change as they grow, but nurturing their curiosity helps them find their true calling.

What’s one habit you want to eliminate and one you want to keep?

Aiming for personal growth, I’ll axe the time-sucking social media scroll and double down on the mood-boosting, energy-zinging exercise routine. Recognizing habits are key, I’ll actively fight for a more balanced and fulfilling life, one mindful step at a time.

Presentation topics are the key to a successful lecture, bringing more opportunities for your career. Choosing among tons of ideas out there can get confusing , but give it a serious thought as your topic impacts your overall presentation.

Our Copy Wins New Patients for Dentists

Welcome to Identiwrite Creative, a family-owned dental copywriting agency. Our team of talented professionals help dentists acquire new patients through content marketing and search engine optimization (SEO).

With over two decades of valuable experience in dental marketing, Owner Shauna Smith Duty understands clinical dentistry and technology, dental patients, and online marketing. Shauna personally trains our copywriters, editors, and SEO experts, so they, too, have a solid grasp on dental marketing.

We primarily work with website development companies, DSOs, dental consultants, and marketing agencies.

If you own a dental marketing agency, consultancy, or website marketing firm, we want to become your copywriting resource. White label our products! Avoid in-house employee costs and headaches like management, H/R, and payroll taxes. We will be your copywriting department.

Just read our reviews to see for yourself that we’re competent, efficient, and reliable.

Having worked with many agencies, Identiwrite has developed systems to manage projects and assignments, which allows us to meet deadlines and provide excellent, polished, professional dental copy. We can even interview your clients, if you so choose. Here’s what we want to do for you:

Dental Content Marketing

Experts agree, original, well-optimized content is key to successful online marketing. Google prioritizes informative information, so if you invest in publishing optimized content, your dental clients’ websites will be rewarded with higher rankings and more traffic, which means more new patients for your clients! (We love to make our clients look amazing.)

• Dental Blogging

Search-engine-optimized dental blogs boost a website to the top of search for targeted keywords, as well as long-tail keywords that may not have been identified in keyword research. Blogs are indexed quickly by Google, because they’re considered news. Weekly blogging has tremendous effects on a dentist’s visibility and traffic, which naturally leads to more new patient calls!

In content marketing, dental SEO is imperative! We teach our copywriters the essential elements of on-page search engine optimization, so dental SEO is worked into all the copy we compose for websites, blogs, articles, and social media. SEO is what brings your target patients to your website. The best way to achieve a great SEO strategy is through keyword research; original, well-optimized content; and evaluation of reports month-over-month and year-over-year.

Newsletters & Emails

The cost of acquiring a new patient is well over $200, minimum. For established dental practices, retention is just as important as getting more new patients. Newsletters and email campaigns help dentists stay in front of and in contact with current patients between preventive appointments. This brand repetition fosters loyalty, which keeps patient numbers and profitability up!

SEO Professional

Hi. My name is Joshua. Currently hailing from Delaware, I'm an SEO professional of 13 years with a knack for understanding computer & web technology. Since 2008, I've helped a few dozen businesses find their target customers through Google Search, spanning multiple markets and industries; from USA to Western Europe.

Think of me as a liaison between Googlebot and your business, OR as a "Search Engine Whisperer", who makes sure your website is compliant with Google's guidelines so that you have the best chance to appear in front of your target audience.

I'm a son of former orchestra musicians, a grandson of a guitarist, and nephew to two violinists, so would it surprise you to know that I have a bit of a passion for music? I love all kinds of music, and in fact, it's music that led me into the world of SEO.

I recognized the power of the internet early on and so desired to create a website that would allow me to teach music to others. But I quickly learned that just because you create a website that doesn't mean you'll generate traffic, especially if no one knows your website exists!

So it was time for me to use my special powers to learn everything I could about Google, Bing and other search engines. The rest is history.

The Trumpification of Kristi Noem

The South Dakota governor’s new teeth are just the latest step in a very MAGA makeover.

By Vanessa Friedman

Vanessa Friedman has been chronicling the use of image as a communication device in politics since the Bush v. Gore election of 2000.

Kristi Noem, the governor of South Dakota, is readying for her national close-up. How else to interpret her recent controversial trip to Texas to “fix” her smile, documented in a lengthy video ?

You know, the one she posted on X, Facebook and Instagram, singing the praises of Smile Texas, the cosmetic dental clinic that remedied what she said had been a problem incurred long ago in an accident while bicycling with her children. The one that chronicled her journey to, she said, “a smile that I can be proud of and confident in.”

The result seemed so much like a promotional infomercial that Travelers United, a consumer advocacy group, is suing Ms. Noem for misleading advertising, claiming she was effectively acting as a travel influencer. Vanity Fair wrote that the whole exercise was “blowing up in her face.”

Except for one thing. The teeth story is about a lot more than teeth.

As the race to be Donald J. Trump’s running mate heats up, Ms. Noem’s new smile reflects a tactical move that has as much to do with politics and psychology as it does with appearance.

“It’s all about her appeal to an audience of one,” Ron Bonjean, a Republican strategist, said. “The whole teeth thing almost looks like it was done for Trump to see. She is showing him she works well in front of the camera, that she has that star power he wants onstage with him, while fitting into the mode of women in the Trump universe.”

Mr. Trump was, after all, the president who often identified his staff members, especially members of the military, as coming from “central casting .” He now dresses almost entirely in the colors of the American flag. He reportedly liked women to “dress like women ” — and, as Richard Thompson Ford, a law professor at Stanford University and the author of “Dress Codes: How the Laws of Fashion Made History,” said, “We know what that means to him.” It is reflected in the profile of almost every woman in the Trump orbit, including his family members and his former press secretary Kayleigh McEnany.

In this, Ms. Noem’s dental upgrade is simply the most recent step in what appears to be a yearslong makeover that has transformed her, more than any other woman on Mr. Trump’s shortlist, into what Samantha N. Sheppard, a professor of cinema and media studies at Cornell University, called “the perfect ornament for Trump.” Even beyond her popularity and credentials as a governor, and her MAGA platform, she offers an example of a certain kind of “Miss America-like white femininity,” Ms. Sheppard said, also reflected in Fox News anchors and that involves cascading hair, extensive eyelashes and a blinding smile.

How does Mr. Trump know she’s part of his team? All he has to do is look.

The story is told in the imagery. Back in 2010, when she was first running for Congress, Ms. Noem had a haircut that looked like a cross between “the Rachel,” the layered, straightened haircut Jennifer Aniston made famous on “Friends,” and the power bob favored by Hillary Clinton and Nancy Pelosi. When she won re-election in 2012, she had chopped it into a short look that Ms. Sheppard compared to the signature haircut of Kate Gosselin from “Jon & Kate Plus 8,” albeit slightly more corporatized.

After Mr. Trump won the presidency and the MAGA movement took off, Ms. Noem adopted a new look. Her hair got longer and longer, with tousled waves kissed by the curling iron, her part moved to the center. She began to resemble a doppelgänger for Kimberly Guilfoyle, Donald Trump Jr.’s fiancée. Or a dark-haired version of Lara Trump, Eric Trump’s wife and the new co-chair of the Republican National Committee. Even Ms. Noem’s clothes changed, from the khaki shirtdress she wore to CPAC in 2011 to the bright blue sheath she chose for her State of the State address this year.

There is no better example of her transformation than the cover photo on her new book , “No Going Back: The Truth on What’s Wrong with Politics and How We Move America Forward,” which features a portrait of Ms. Noem with lips glossed, eyelashes thick and one hand seemingly playing with her wavy locks as she sits in her desk chair in a blazer and dress before the American flag.

“She practically looks like a member of the Trump family,” Mr. Bonjean said. “Maybe a cousin.”

And while her Trumpification could be a coincidence, Ms. Noem has revealed herself to be sensitive to the effects and uses of costuming, as seen in recent ads in which she dressed up as a dental hygienist, an electrician and a highway patrolman, the better to convey the idea that “South Dakota is hiring.” (“We have over 20,000 open jobs,” she says in one ad. Plus no individual income tax!)

“It’s absolutely strategic,” Mr. Ford said. Ms. Noem is “signaling that she’s going to be Trump’s kind of woman. And, at the same time, that she isn’t going to challenge him.”

This approach to political image-making has its roots in the pantomimed femininity of Phyllis Schlafly and Sarah Palin, where the promise of a powerful woman was defanged by her participation in the pageantry of traditional gender cosplay.

The teeth simply finish the picture, as does the fact that Ms. Noem used the opportunity to talk up the dentist who did the procedure. If anyone would recognize the value of using power to push product it is Mr. Trump himself. And perhaps, in doing so, recognize a kindred spirit.

The governor may sell herself in part as a grass-roots cowgirl, but Ms. Noem is speaking Mr. Trump’s language, proving that she belongs and that she is all in with his vision. That she is going to “get in line and stay in line,” Ms. Sheppard said. “That she knows how to conduct herself and be who he needs her to be.”

In any case, he has clearly noticed. A few days after the tooth news broke, Ms. Noem joined Mr. Trump at a rally for the Senate candidate Bernie Moreno in Vandalia, Ohio. After she spoke — they were wearing matching MAGA hats — Mr. Trump announced : “You’re not allowed to say it, so I will not. You’re not allowed to say she’s beautiful, so I’m not going to say it.”

What could she do but smile?

Second-half surge powers No. 11 NC State to unlikely Final Four berth with defeat of Duke

DALLAS — One of the great postseason runs in men’s college basketball history keeps on going. Next up for the NC State show? The Final Four. 

For the first time since 1983 — the year they won it all with Jim Valvano running around The Pit in New Mexico hugging anyone he could find — NC State is back on the sport’s biggest stage. 

And to make it even sweeter, the Wolfpack beat rival Duke to get there on Sunday in an all-ACC matchup, dominating the second half of the South Regional final to mint a 76-64 victory that will live forever in NC State lore. 

NC State, a team that finished 10th in the ACC regular season and stood at 17-14 when the conference tournament began, has now rattled off nine straight wins and will face No. 1 seed Purdue on Saturday in Glendale, Arizona, for a spot in the national championship game. They’re the sixth team in tournament history to reach the Final Four as a No. 11 seed.

And the main reason the Wolfpack have been transformed over the past three weeks? It’s DJ Burns, Jr., the charismatic 6-foot-9 center with a feathery touch and passing skills that do not seem possible for someone carrying well over 300 pounds (he’s officially listed at 275).

FOLLOW THE MADNESS: NCAA basketball bracket, scores, schedules, teams and more.

With Duke choosing to use just only defender most of the time to guard him — just as they did in two earlier meetings this season — Burns ate the Blue Devils' defense alive with 29 points on 13-of-19 shots. 

NC State also got timely outside shooting from senior guard DJ Horne, who scored 18 and sparked second half in which the Wolfpack made 19-of-26 shots. 

Duke, meanwhile, could never get settled on offense, shooting 32 percent overall and 5-of-20 from the 3-point line. The Blue Devils got poor games from sophomore big man Kyle Filipowski (11 points on 3-of-12 shooting) and sophomore guard Tyrese Proctor (0 points, 0-for-9) and simply could not mount a response once NC State began to get its second-half rhythm. 

NC State seemed to be in foul trouble early in the second half when Burns picked up his third with 15:11 remaining and Mohamed Diarra, its other big man, was called for his fourth with 12:41 left. 

But NC State coach Kevin Keatts managed to nurse his rotation just enough to keep Burns on the floor most of the time, and it paid off with easy looks at the rim out of their halfcourt sets. 

The first half finished with both teams struggling to unlock their offense. NC State made just 9-of-34 field goals, struggling both from the 3-point line (1-of-7) and finishing at the rim where they continually ran into a wall of resistance.

Duke also shot poorly (8-of-26) and committed five turnovers but managed to get to the foul line with more frequency, making all nine to account for their 27-21 lead.  

But Duke’s lead was a mirage: Possession by possession, NC State was sharper, more aggressive and never looked back once Horne gave the Wolfpack a 40-38 lead on a runner with 11:39 left. 

NC State is making its fourth trip to the Final Four in school history. It won the national championship in 1974 and 1983, the latter of which is considered one of the great longshot runs in tournament history as a No. 6 seed.
