Medicaid Dental Benefits for Pregnant People and Dental Care Use Among Very Young Children.

OBJECTIVES: The aim of this study was to examine the association between Medicaid dental benefits for pregnant people and dental care use among very young children in Medicaid. We hypothesized that children living in states with more generous dental benefits for Medicaid-enrolled pregnant people would be more likely to have a recent dental visit. METHODS: This national cross-sectional study used pooled 2017-2019 data from the National Survey of Children's Health, as well as state Medicaid policy data. The study sample included children aged 0-2 enrolled in Medicaid. Multivariable logistic regression models estimated the association between Medicaid dental benefit generosity for pregnant people and the child having a dental visit in the past year. RESULTS: Children in states with emergency-only dental coverage for pregnant people were 2.5 times as likely to have had a dental visit than children in states with extensive coverage (OR 2.48, 95% CI 1.35-4.53). In supplemental analyses excluding children living in Texas, there was no longer an association between dental coverage for pregnant people and dental utilization among young children (OR 1.52, 95% CI 0.82-2.83). CONCLUSIONS FOR PRACTICE: Young children in states that provided emergency-only dental benefits for pregnant people in Medicaid had significantly higher odds of dental utilization than young children in states with more generous dental benefits for pregnant people. This relationship disappeared after excluding the state Texas, which had the highest rate of child dental utilization in the country and provided emergency-only dental benefits for pregnant people in Medicaid.

Effect of silver nanoparticles associated with fluoride on the progression of root dentin caries in vitro.

OBJECTIVES: To assess the anti-proteolytic effect and potential to inhibit dentin root caries progression of a silver nanoparticle and fluoride solution (CNanoF) in comparison to silver diamine fluoride (SDF). METHODS: 48 specimens of root dentin artificial caries lesion were treated with 38% SDF, CNanoF, CNano or F (n = 6 per group). Ph cycling with demineralization and remineralization solutions simulated caries lesion progression. In addition, specimens were incubated with or without bacterial collagenase in the remineralization solution to induce dentin proteolytic degradation. Dentin degradation was assessed by weight loss rate and hydroxyproline (Hyp) release. Changes in cross-sectional microhardness, and lesion permeability and collagen integrity as determined by confocal laser scanning microscopy indicated potential for further demineralization inhibition. The effect of the solutions on the activity of metalloproteinases (MMP) -2 and -9 was also investigated. Statistical analysis consisted of ANOVA, Kruskal-Wallis, and linear mixed models with post-hoc pairwise Tukey, Dunn, and t-tests (α = 0.05). RESULTS: Treatment with SDF resulted in lower weight loss rate than did other solutions, but all groups showed similar Hyp release (p = 0.183). SDF resulted in greater microhardness at superficial layers of the caries lesions (p<0.05), while there were no differences among CNanoF, CNano, and F. Lesion permeability was similar among all groups after pH cycling (p>0.05), with or without the use of collagenase (p = 0.58). No statistically significant difference was noted among solutions regarding collagen integrity after pH cycling; however, SDF-treated dentin had a significant decrease in collagen integrity when collagenase was used (p = 0.003). Interestingly, only SDF was able to completely inactivate MMP-2 and -9. CONCLUSIONS: CNanoF and SDF both potentially prevent dentin degradation during caries lesion progression in vitro; however, SDF was more effective at inhibiting further tissue demineralization.

Triad multisystem phenotype with high risk for developing temporomandibular disorders-characteristics and potential pathophysiology results from the Orofacial Pain: Prospective Evaluation and Risk Assessment dataset.

ABSTRACT: A multisystem phenotype with the Triad of bodily pain, psychological distress, and sleep disturbance was found to have high risk for developing initial onset of painful temporomandibular disorders (TMDs) in the multicenter Orofacial Pain: Prospective Evaluation and Risk Assessment dataset. In this study, we systemically examined phenotypic characteristics and explored potential pathophysiology in quantitative sensory testing and autonomic nervous system domains in this multisystem Triad phenotype. Secondary analysis was performed on 1199 non-Triad and 154 Triad TMD-free Orofacial Pain: Prospective Evaluation and Risk Assessment enrollees at baseline. Results indicated that before developing TMDs, the Triad phenotype demonstrated both orofacial and systemic signs and symptoms that can only be captured through multisystem assessment. In addition, we found significantly lower resting heart rate variability and higher resting heart rate in the Triad phenotype as compared with the non-Triad group. However, pain sensitivity measured by quantitative sensory testing was not different between groups. These findings highlight the importance of whole-person multisystem assessment at the stage before developing complex pain conditions, such as TMDs, and suggest that, in addition to a "tissue damage monitor," pain should be considered in a broader context, such as a component within a "distress monitoring system" at the whole-person level when multisystem issues copresent. Therefore, the presence or absence of multisystem issues may carry critical information when searching for disease mechanisms and developing mechanism-based intervention and prevention strategies for TMDs and related pain conditions. Cardiovascular autonomic function should be further researched when multisystem issues copresent before developing TMDs.

Patterns of fluoride intake from 6 to 17 years of age: The Iowa Fluoride Study.

OBJECTIVES: This article reports on estimated daily fluoride intake from water, other beverages and selected foods, dentifrice, and dietary fluoride supplements by both individual sources, and all sources combined, among 787 children participating in the Iowa Fluoride Study (IFS) from 6 to 17 years of age. METHODS: Total daily fluoride intake (mg F) and fluoride intake per kilogram bodyweight (mg F/kg bw) were estimated using responses to questionnaires sent every 3-6 months. Dietary assessments included frequencies and amounts of beverage intake for the previous week from water, milk, ready-to-drink beverages, beverages made by adding water to concentrate or powder, and selected foods with substantial water content. Descriptive statistics and bivariate and multivariable analyses with linear mixed models were used to assess associations with each of mg F and mg F/kg bw. RESULTS: Mean combined dietary fluoride (mg F) from all sources examined in the study increased slightly with age, whereas the fluoride intake per kg bw decreased with age. Age, sex, and socioeconomic status were significantly associated with fluoride intake (mg F and mg F/kg bw). Each year increase in age was associated with a 0.02-mg increase in fluoride consumption, on average, after adjusting for the effects of covariates. CONCLUSIONS: Daily mean fluoride intakes from single and combined sources were relatively stable, while the intake of fluoride per kg bw decreased from 6 to 17 years of age. Fluoridated water was the major source of ingested fluoride, contributing over 50% of total daily intake at all ages.

Fracture resistance of defective amalgam restorations repaired with a resin-based composite material.

BACKGROUND: Repair is used to increase the longevity of defective restorations, such as large amalgams. The aim of this study was to investigate the fracture resistance and fracture modes of mesio-occlusodistal (MOD) amalgam molar restorations with extensive cuspal fracture repaired or replaced using a bulk-fill resin-based composite material. METHODS: Amalgam restorations were placed in 84 permanent extracted molars and randomly assigned (n = 14) to groups: (1) MOD amalgam, (2) composite repair of 1-cusp fracture and adjacent proximal box, (3) composite repair of 1-cusp fracture, (4) composite repair of 2-cusp fracture, (5) replacement of 1-cusp defect and existing MOD amalgam, (6) replacement of 2-cusp defect and MOD amalgam. Each molar was prepared to simulate the assigned fracture and either repaired or replaced. Specimens were aged and then loaded to fracture. Fracture resistance and fracture modes were recorded. RESULTS: The authors found significant differences (P < .001) between group 4 (1,652.3 N) and groups 5 (3,095.0 N), 1 (2,669.8 N), 6 (2,658.6 N), and 2 (2,442.9 N) as well as between group 3 (2,133.5 N) and group 5 (3,095.0 N). The results of the Fisher exact test showed differences among groups (P < .001), with group 5 having the highest number of nonrestorable fractures as well as higher fracture resistance on average. CONCLUSIONS: Composite material is a viable option for the repair and replacement of cuspal defects, especially in the case of a 1-cusp fracture and 1-cusp fracture involving the adjacent proximal box. PRACTICAL IMPLICATIONS: Within the limitations of this study, the repair of cusp fractures in existing MOD amalgam-restored molars is an appropriate treatment option, although replacement of the defect and existing restoration with resin-based composite will withstand higher forces.

Dentist attitudes toward an annual benefit maximum in Iowa's adult Medicaid program.

OBJECTIVES: The Dental Wellness Plan (DWP) provides dental coverage for adult Medicaid enrollees in Iowa. In September 2018, a $1000 annual benefit maximum (ABM) was implemented in the DWP program. The aim of this study was to explore private dentists' attitudes toward ABMs and factors associated with ABM attitudes. METHODS: The data source was a mailed survey administered in spring 2019 to all private practice dentists in Iowa. The two dependent variables were (1) attitude toward the $1000 ABM and (2) attitude toward any ABM generally. Independent variables included demographic and practice-related factors, and participation in and attitudes toward the DWP. Descriptive, bivariate, and multivariable analyses were conducted. RESULTS: While over half (56%) of providers reported a positive attitude toward "Any ABM," less than half (40%) reported a positive attitude toward the "$1000 ABM." Attitudes toward both "$1000 ABM" and "Any ABM" were significantly and positively associated with attitudes toward DWP overall and toward DWP structure. Independent variables that were significantly associated with both the "$1000 ABM" and "Any ABM" included overall attitude toward the DWP, attitude toward DWP structure, and practice busyness. CONCLUSIONS: Utilizing an ABM, particularly one set at $1000 for a Medicaid program, elicits mixed attitudes among dentists. Future research should evaluate the impact of Medicaid ABMs on long term dentist participation and patient's ability to receive needed care.

Development and validation of a nursing home mortality index to identify nursing home residents nearing the end of life in dental clinics.

BACKGROUND: Nursing home (NH) residents seek care at dental offices, yet many of them are at the end of life. The uncertain life expectancy further complicates the care of NH residents. This study aimed to develop and validate a Nursing Home Mortality Index (NHMI) to identify NH residents in the last year of life. METHODS: Logistic modeling was used to develop predictive models for death within 1 year after initial appointment by utilizing the new patient examination data and mortality data of 903 Minnesota NH residents. The final model was selected based on areas under the curve (AUC) and then validated using data from 586 Iowa NH residents. Based on the final model, the NHMI was developed with the estimated 1-year mortality for the low, medium and high risk group. RESULTS: One-year mortalities were 21% and 26% in the development and validation cohorts, respectively. Predictors included age, gender, communication capacity, physical mobility, congestive heart failure, peripheral vascular disease, cancer, cerebrovascular disease, chronic renal disease and liver disease. AUCs for the development and validation models were 0.73 and 0.68, respectively. For the validation cohort, the sensitivity and specificity were 0.79 and 0.53, respectively. The estimated 1-year mortality risks for three risk groups were 0%-10%, 11%-19%, and ≥20%, respectively CONCLUSION: The high mortality rate of NH residents following a dental exam highlighted a need to incorporate patients' prognoses in treatment planning along with normative needs and patients' preferences. The NHMI provides a practical way to guide treatment decisions for end-of-life NH residents.

A Social Media Intervention for Promoting Oral Health Behaviors in Adolescents: A Non-Randomized Pilot Clinical Trial.

Poor oral hygiene and excessive consumption of soda are among the main drivers of systemic health issues in adolescents in the United States. This non-randomized pilot clinical trial focused on the effects of a health text message system and smartphone-based intervention on adolescent tooth-brushing behavior and dietary choices, with a convenience sample of 94 participants aged 12 to 14 years old. A group of 75 participants agreed to use a tooth-brushing app and received a health text message; the other group of 15 agreed to use the tooth-brushing app, but did not receive a health text message. Saliva specimens were collected directly before and at the end of each experiment; changes in the salivary presence of cariogenic bacteria over the duration of the study were evaluated and compared with the demographics and behavioral variables. Within the text message group, 5% of participants increased the frequency of daily tooth brushing. Within the non-intervention group, 29% of participants increased the frequency of their daily tooth brushing. There were reductions in the total salivary bacteria and total streptococci in both groups (p < 0.001), but no change in the presence of cariogenic Mutans streptococci. Raising adolescents' consciousness of oral health behavior resulted in marginal to moderate improvements to oral hygiene and dietary choices, as well as reductions in total salivary bacteria.

Systematic review and meta-analysis of oral squamous cell carcinoma associated oral microbiome.

The intersection between the human oral microbiome and oral health is an emerging area of study which has gained momentum over the last decade. This momentum has motivated a search for associations between the oral microbiome and oral cancer, in hopes of identifying possible biomarkers that facilitate earlier diagnosis and improved prognosis for patients with that disease. The present study examined the relationship between the microbiome in the human oral cavity and oral squamous cell carcinoma (OSCC). We searched the literature for case-control studies which focused on the relationship between the human oral microbiome and OSCC. We aggregated three types of data from these studies: bacteriome data at the genus level, predicted functional pathway data, and gene abundance data. From these data, we noted several microbial genera which may be associated with oral cancer status, including Fusobacterium. We also identified functional pathways which merit further investigation, including RNA degradation (ko03018) and primary immunodeficiency (ko05340). In addition, our analysis of gene abundance data identified the gene K06147 (ATP-binding cassette, subfamily B, bacterial) as being over abundant in OSCC samples. Our results are generalizations which identified some currents that we believe could guide further research. Our work faced several limitations related to the heterogeneity of the available data. Wide variation in methods for sample collection, methods for controlling for known behavioral risk factors, computing platform choice, and methods for case-control design all posed confounding factors in this work. We examined the current methods of data collection, data processing, and data reporting in order to offer suggestions toward the establishment of best practices within this field. We propose that these limitations should be addressed through the implementation of standardized data analytic practices that will conform to the rigor and reproducibility standards required of publicly funded research.

Development of Proanthocyanidin-Loaded Mesoporous Silica Nanoparticles for Improving Dental Adhesion.

Dentin biomodification is a promising approach to enhance dental tissue biomechanics and biostability for restorative and reparative therapies. One of the most active dentin tissue biomodifiers is proanthocyanidin (PAC)-rich natural extracts, which are used in the dental bonding procedure in combination with resin-based adhesives (RBAs). This study aimed to investigate the use of mesoporous silica nanoparticles (MSNs) for the sustained delivery of PACs for dentin biomodification as a novel drug-delivery system for dental applications. The effects of the incorporation of MSN functionalized with 3-aminopropyltriethoxysilane (APTES) and loaded with PAC into an experimental RBA were assessed by characterizing the material mechanical properties. In addition, the immediate and long-term bonding performance of an experimental resin-based primer (RBP) containing MSN-APTES loaded with PAC was also evaluated. For that, different formulations of RBA and RBP were prepared containing 20% w/v MSN-APTES loaded with PAC before or after functionalization (MSN-PAC-APTES and MSN-APTES-PAC, respectively). The incorporation of MSN-APTES-PAC did not negatively impact the degree of conversion or the overall mechanical properties of the RBA. However, adding MSN-PAC-APTES resulted in inferior mechanical properties of the experimental RBA. In the adhesion studies, APTES-functionalized MSN was successfully added to an experimental RBP for drug-delivery purposes without compromising the bond strength to the dentin or the failure mode. Interestingly, the sequence of surface functionalization with APTES resulted in differences in the bonding performance, with better long-term results for RBP containing MSN loaded with PAC after functionalization.

Conceptualizing the next patient interaction: A clinical skillset using an emulation model in critical thinking.

CONCEPTUALIZING: The next patient interaction is logical, essential, and largely done intuitively. MAIN PURPOSE: To design and test a succinct learning guide for student guidance and student-faculty interaction in conceptualizing the next patient interaction. METHODS: In 2021 and 2022, faculty scored questions from 1-5: Recognize deviation from the ideal? Articulate how and how much the situation deviated? Gage consequences of the situation? Assess own capabilities? To what extent does the student have a clear grasp of the procedural outcome? Faculty were also given open-ended questions. RESULTS: Forty-eight reports were completed, 25 D3 and 23 D4. Three hundred thirty-five faculty entries were made in the questions calling for a 1-5 response out of a possible 336 responses. Statistically significant differences were noted. Students were better able to recognize the situation as different from ideal than to articulate how and how much the situation deviated. Students were better able to grasp how and how much this situation differs from the ideal than to assess own capabilities. D4 students were better able to recognize deviation from the ideal and to articulate how and how much the situation deviated than were D3 students. For open-ended questions, more students were scored as "Prepared" than were scored as "Unsure" and "Missed" combined. CONCLUSIONS: The exercise is seen as a succinct and constructive (nonjudgmental) path to guide the student's conceptualization of the next patient encounter before the encounter begins. Next steps will be incremental for wider use in a clinical teaching environment.

A tool for incorporating interprofessional perspectives into dental students decision-making: A 2-year follow-up on this learning outcome.

OBJECTIVES: To analyze student performance when using a sustainable teaching tool developed to guide learning toward interprofessional perspectives. METHODS: This study compiled data about D4 students' performance when using an interprofessional education (IPE) teaching tool reported previously in this journal, during their 5-week Geriatric and Special Needs Program rotation in the academic years 2018-2019 and 2019-2020. Ninety-two students were introduced to IPE concepts and teaching tools during their orientation. Students were then asked a question regarding the perspective of each healthcare team member and whether they would contact these healthcare team members for collaboration during the provision of oral care with regard to various patient cases. Students were scored on whether they answered the question about the perspective of each health care team member. The same two independent evaluators also noted whether the student thought each member of the health care team should be contacted. RESULTS: A majority (90.2%-95.7%) of dental students applied their knowledge to questions regarding each health care team member's perspectives. The profession that dental students most often indicated they wished to contact for collaboration was primary care providers (n = 70; 76.1%), followed by family caregivers (n = 54; 58.7%), and pharmacists (n = 46; 50.0%). The results of the interrater agreement between the two-faculty scoring students were between 86.7% and 100%. CONCLUSIONS: The teaching tool is sustainable and succinct. Students considered the perspectives of each health care team member at a rate above 90%, and the interrater agreement was high among the faculty evaluators. Students considered contacting primary care providers, family caregivers, and pharmacists more often than the other health care team members. We see this model as one approach to begin the articulation of learning outcomes for IPP.

Perceived Didactic Curricular Effectiveness of In-Person vs. Virtual Formats amongst Fourth-Year Dental Students.

PURPOSE: The COVID-19 pandemic altered the methodologies of dental education delivery, resulting in both immediate and more enduring changes. To assess student perceptions of learning effectiveness, graduating dental students from the class of 2020 were surveyed to identify student comfort with technology and content retention, individual motivation and mental focus, and access to resources pertaining to an abrupt transition to a virtual learning didactic seminar approach in March 2020. METHODS: a voluntary, 18-question electronic survey was distributed to fourth-year dental students prior to graduation to assess perceptions of learning outcomes and preferences of a virtual seminar format relative to previous in-person didactic seminars experienced. RESULTS: 34 of 80 dental students (42.5%) completed the electronic survey. Comfort and retention of concepts through virtual learning were reported ≥ by 91% and 85% of the respondents, respectively. Increased distractions and multitasking were reported with virtual learning in 56% and 71%, respectively. Desires to have all teaching conducted through virtual learning platforms was reported at 21%. CONCLUSIONS: the positive student responses obtained when comparing virtual to in-person seminars in the survey assessment demonstrates the long-term potential for such delivery modalities to be intentionally incorporated into an evolving predoctoral curriculum in a hybrid nature.

Genome-Wide Scan for Parent-of-Origin Effects in a sub-Saharan African Cohort With Nonsyndromic Cleft Lip and/or Cleft Palate (CL/P).

OBJECTIVE: Nonsyndromic cleft lip and/or cleft palate (NSCL/P) have multifactorial etiology where genetic factors, gene-environment interactions, stochastic factors, gene-gene interactions, and parent-of-origin effects (POEs) play cardinal roles. POEs arise when the parental origin of alleles differentially impacts the phenotype of the offspring. The aim of this study was to identify POEs that can increase risk for NSCL/P in humans using a genome-wide dataset. METHODS: The samples (174 case-parent trios from Ghana, Ethiopia, and Nigeria) included in this study were from the African only genome wide association studies (GWAS) that was published in 2019. Genotyping of individual DNA using over 2 million multiethnic and African ancestry-specific single-nucleotide polymorphisms from the Illumina Multi-Ethnic Genotyping Array v2 15070954 A2 (genome build GRCh37/hg19) was done at the Center for Inherited Diseases Research. After quality control checks, PLINK was employed to carry out POE analysis employing the pooled subphenotypes of NSCL/P. RESULTS: We observed possible hints of POEs at a cluster of genes at a 1 mega base pair window at the major histocompatibility complex class 1 locus on chromosome 6, as well as at other loci encompassing candidate genes such as ASB18, ANKEF1, AGAP1, GABRD, HHAT, CCT7, DNMT3A, EPHA7, FOXO3, lncRNAs, microRNA, antisense RNAs, ZNRD1, ZFAT, and ZBTB16. CONCLUSION: Findings from our study suggest that some loci may increase the risk for NSCL/P through POEs. Additional studies are required to confirm these suggestive loci in NSCL/P etiology.

Repair versus replacement of defective direct restorations: A cross-sectional study among US dentists.

BACKGROUND: Repair increases the longevity of restorations and is well-accepted by patients. In this study, the authors assessed the acceptance of dental restoration repair by dentists and determined the main variables of repair versus replacement of defective restorations. METHODS: A 15-item questionnaire was developed and distributed electronically to the American Dental Association Clinical Evaluators panel members (n = 785) during a 2-week period in 2019. Descriptive, bivariate, and multivariable analyses were conducted. RESULTS: Of the 387 respondents, 83.7% stated that they repair defective restorations, and 16% stated that they always replace them. Reasons to forego a restoration repair among dentists who perform repairs included defect size and carious lesion extension (42%) and negative personal experience or lack of success (37.9%). However, the latter was considerably higher for dentists who do not perform repairs (60.7%). The most commonly cited patient-related reason and tooth condition to repair restorations were limited patient finances (67%) and noncarious marginal defects (86%), respectively. Neither sex nor age group was significantly associated with the practice of restoration repair (P = .925 and P = .369, respectively). However, sole proprietors were more likely to perform repairs than those in an employee, associate, or contractor practice setting (P = .008). The most significant reason to forego restoration was negative experience or lack of success (P = .002). CONCLUSIONS: Restoration repair is considered a treatment option for managing defective restorations. Negative personal experience or lack of success and practice setting influenced the dentists' decision to repair or replace a defective restoration. PRACTICAL IMPLICATIONS: Understanding dentists' clinical challenges and practice environment is necessary when advocating for this approach.

Surgery start time and early implant failure: A case-control study.

OBJECTIVE: To evaluate the influence of surgery start time (SST) and other patient- and therapy-related variables on the risk for early implant failure (EIF) in an academic setting. MATERIAL AND METHODS: Data were extracted from the electronic health records of 61 patients who had at least one EIF and 140 age- and gender-matched, randomly selected, non-EIF controls. Bivariate and multivariable analyses were performed to identify relevant associations between EIF and different variables, such as SST. RESULTS: Incidence of EIF was not significantly associated with SST (HR: 1.9 for afternoon implant placement, 95% CI: 0.9-3.9; p = .105). Other factors that were associated with a significantly increased risk for EIF in a multivariable model were pre-placement ridge augmentation (HR: 7.5, 95% CI: 2.2-25.1; p = .001), intra-operative complications (HR: 5.9, 95% CI: 2.2-16.3; p < .001), simultaneous soft tissue grafting (HR: 5.03, 95% CI: 1.3-19.5; p = .020), simultaneous bone grafting (HR: 3.7, 95% CI: 1.6-8.8; p = .002), and placement with sedation (HR: 3.4, 95% CI: 1.5-7.5; p = .002). CONCLUSIONS: While SST was not associated with the occurrence of EIF in our cohort, other variables, such as ridge augmentation prior to implant placement, simultaneous bone or soft tissue grafting, intra-operative complications, implant placement with sedation, and number of implants in the oral cavity, were associated with an increased risk for this adverse event.

Students' perceptions and attitudes about digital dental technology is associated with their intention to use it.

PURPOSE/OBJECTIVES: To investigate factors associated with predoctoral students' intention to use dental technology in future practice using the theory of planned behavior. METHODS: A comprehensive survey was developed consisting of 29 questions grouped in three main domains: knowledge, perception, and suggestions. After students had completed their digital dentistry didactic courses in 2019, the University of Iowa-College of Dentistry and Dental Clinics D2, D3, and D4 classes completed the survey. The D1 class was excluded because they had not finished their digital dentistry didactic courses. The survey data were tabulated for each class separately to compare trends among classes. Each response was analyzed individually before creating scores for the various subdomains. A linear regression analysis was used to create the final model for the outcome variable (intention to use technology). RESULTS: The response rate was 95% (n = 232). The mean age of participants was 25.7 years (SD = 2.7). There were significant differences between the classes in their knowledge (p < 0.0001), perceived quality of training (p < 0.0001), and all perceptions related to digital dentistry. Controlling for significant covariates among higher level students, there were significant associations between intention to use dental technology and greater knowledge scores (p = 0.05), attitude (p < 0.0001), subjective social norms (p = 0.02), and perceived control on the future use of technology (p < 0.0001). CONCLUSIONS: Students may be motivated to use digital technology when they have good knowledge, feel that others are using it or endorsing its use, and perceive that they have control in their future practice.

Types of dental procedures provided to adults with autism spectrum condition: A descriptive study.

PURPOSE/AIM: To investigate demographic and systemic health characteristics, and the types of dental procedures performed for adults with autism that had sought care at a dental school. MATERIALS AND METHODS: De-identified data were collected from the records of patients aged 18+ who have self-reported autism. Each patient's age, gender, BMI, mental health, heart disease, xerostomia, tobacco use, alcohol use, diabetes, use of drugs, seizures, and total number of medications, as well as the type and number of dental codes used in the care of that patient within each code category were included as variables. RESULTS: The sample was composed by 244 patients. Mean age was 29.8 years (±12.3), 64.8% were males, and mean BMI was 29.9 (±8.1). Mental health condition was reported by 79.9%, heart disease by 25.4%, xerostomia by 21.7%, 20.9% reported using tobacco, 18.9% reported using alcohol, 14.8% reported having diabetes, 10.2% reported using drugs, and 3.7% reported having seizures. The median number of dental procedures per patient was nine, and exams, preventive, operative, and surgical procedures were the most common ones. CONCLUSIONS: Adult patients with autism were overweight/obese young males. Most common dental procedures were exams, followed by preventive, operative, and surgical procedures.

COVID-19 pandemic and its impact on dental students: A multi-institutional survey.

PURPOSE/OBJECTIVES: To investigate dental students' perceptions and concerns regarding the COVID-19 pandemic, their coping strategies and support resources, and their perceived stress levels. METHODS: A customized 19-item survey and the perceived stress scale (PSS) were applied to undergraduate dental students from the US, Spain, Ireland, Chile, India, and Brazil between April 10 and July 5, 2020. Linear modeling and mediation analysis were used to explore the relationships among demographics, stressors, coping mechanisms, social support, and stress RESULTS: A total of 4475 students responded to the survey. The majority (72.4%) were women, and 52.3% had no COVID-19 training at the time of the survey. The students reported that they had to accommodate to changes in patient care (96.6%) and didactic learning (95.2%) activities, while 88.5% of the respondents indicated at least one of their courses moved online. Transition to online courses went "smoothly with some troubles" for 51.8% of the respondents, and 48.3% perceived the faculty as prepared for the online transition; however, 45.9% reported feeling extremely concerned about the impact of COVID-19 on their education. The average PSS score was 21.9 of 40 (moderate stress). Multivariate models were built for participants with full data (n = 3899). Being male, having completed more dental coursework, and perceiving a smoother transition were associated with lower PSS scores; more concern about academic progress was associated with higher PSS. Faculty support mediated the relationship between a smoothness of transition and concern about academic progress and PSS scores CONCLUSION: Stress caused by the pandemic may be alleviated by smoother transition and good faculty support.

Cluster randomized control trial of nursing home residents' oral hygiene following the Mouth Care Matters education program for certified nursing assistants.

AIMS: The purpose of this study was to determine if the number of certified nursing assistants (CNAs) trained with the Mouth Care Matters (MCM) oral health educational program had an impact on nursing facility (NF) resident oral health. MATERIALS AND METHODS: Three NFs participated in a cluster randomized control trial. In NF-A: all CNAs were offered the MCM program, NF-B: 3 CNAs were offered the MCM program, and NF-C: Control (no CNAs were offered the MCM program). Demographic information, systemic health data, and oral health data at baseline, 3-month, and 6-month intervals were collected and analyzed using Kruskal-Wallis, Wilcoxon signed-rank and Wilcoxon rank-sum tests. A total of 24 dentate residents participated in this study. Plaque control record scores for NF-A were significantly reduced compared to NF-B and NF-C (P < .001 and P = .002 respectively) and gingival bleeding index for NF-A were significantly reduced compared to NF-B and NF-C (P = .002 and P < .001 respectively). CONCLUSION: Increasing the number of CNA's trained in the Mouth Care Matters educational program positively impacted NF residents' oral hygiene.
