Association between low fluoride exposure and children's intelligence: a meta-analysis relevant to community water fluoridation.

OBJECTIVES: Previous meta-analyses have mainly focused on studies conducted in endemic fluorosis areas with relatively high fluoride concentrations. These are impoverished rural communities in China, India, and Iran, and the findings cannot be generalised to developed countries. Therefore, we investigated the association between fluoride concentrations relevant to community water fluoridation and children's cognition measured with IQ scores by synthesising effect sizes reported in observational studies. METHODS: A previous meta-analysis and the National Toxicology Program database that included a search of multiple databases and the authors' search of PubMed, Google Scholar, and Mendeley provided the data. Cross-sectional and cohort studies examining the association between fluoride and children's cognition and intelligence scores were selected. Two reviewers abstracted data using standard procedures. We performed three meta-analyses to synthesise the effects using the random effects models. RESULTS: Eight studies of standardized mean difference in IQ scores from non-endemic fluorosis areas found no statistically significant difference between recommended and lower levels of fluoride (standardized mean difference = 0.07; 95% confidence interval: -0.02, 0.17; I2 = 0%), and no significant fluctuation in IQ scores across the differences in fluoride concentrations by non-linear modeling with restricted cubic spline (P = 0.21). Meta-analyses of children's and maternal spot urinary fluoride associated pooled regression coefficients (Betachildren = 0.16; 95% confidence interval: -0.40, 0.73; P = 0.57; I2 = 0%, Betamaternal = -0.92; 95% CI: -3.29, 1.46; P = 0.45; I2 = 72%) were not statistically significant. Further regression analysis by standardizing absolute mean IQ scores from lower fluoride areas did not show a relationship between F concentration and IQ scores (Model Likelihood-ratio test: P-value = 0.34.) CONCLUSIONS: These meta-analyses show that fluoride exposure relevant to community water fluoridation is not associated with lower IQ scores in children. However, the reported association observed at higher fluoride levels in endemic areas requires further investigation.

Payment Methods and Demographics Influence Patterns of Dental Service Utilization.

OBJECTIVE: To describe the patterns of specific dental service utilization among the various sociodemographic groups in North Carolina served by the East Carolina University School of Dental Medicine (ECU SoDM). DESIGN: This was a descriptive study utilizing self-reported patients' sociodemographic information, payment method history, and CDT codes of procedures performed. Deidentified clinical data recorded for 26 710 patients and 534 983 procedures from 2011 to 2020 were extracted from a centralized axiUm database. Data were analyzed using IBM SPSS Statistics, version 25.0. Cross-tabulations between dental service utilizations, patients' demographics, and payment method were performed using chi-square analysis. SETTING: Nine dental clinic sites across the state of North Carolina. PARTICIPANTS: In total, 26 710 adults 23 years to older than 65 years were included in the sample for this study. MAIN OUTCOME MEASURES: In total, 534 983 procedure codes completed for the eligible patients were cross-tabulated with payment method. RESULTS: Payment method was significantly related to individual characteristics including location of service, age, race, ethnicity, and untreated decay ( P < .001). Payment method is associated with the dental service type utilized by an individual ( P < .001). Patients who received Medicaid benefits were more likely to receive restorative procedures, removable prosthetics, or oral surgery. Despite NC Medicaid covering preventive procedures, patients who received Medicaid benefits showed lower utilization of preventive procedures than expected. Privately insured or self-paying individuals demonstrated a greater variety of service option utilization, as well as more frequent usage of more specialized procedure options such as endodontics, periodontics, fixed prosthodontics, and implants. CONCLUSIONS: Payment method was found to be related to patients' demographics and type of dental service utilized. Adults older than 65 years demonstrated a higher proportion of self-payment for dental care, indicating a lack of payment options for this population. In the interest of providing care for underserved populations in North Carolina, policy makers should consider expanding dental coverage for adults older than 65 years.

County-level correlates of dental service utilization for low income pregnant women. Ecologic study of the North Carolina Medicaid for Pregnant Women (MPW) program.

BACKGROUND: Dental care utilization for low income pregnant women is met with challenges in the traditional dentist-centered model of care. County-level measures provide insights for policy and roles for stakeholders that extend beyond the dentist-patient relationship. We examined county-level data to generate hypotheses about factors that influence utilization of dental services in North Carolina's Medicaid for Pregnant Women (MPW) program. METHODS: County-level Medicaid utilization data for dental services for 2014-2016 were pooled to get mean county estimates of dental utilization in the MPW program. Descriptive statistics and multivariate regression models of dental utilization and county-level measures are presented. Data used were collected by NC Child and the Robert Wood Johnson Foundation's County Health Rankings Reports. USDA Economic Research Service data were used to categorize counties in terms of Farming, Recreation, Persistent Poverty, and metro/non-metro status using Rural Urban Continuum Codes. RESULTS: Dental utilization ranged from 1-26% with a median of 8.5% across the 100 counties of North Carolina. Strong patterns linking utilization of dental services in the MPW program to contextual social measures of well-being emerged, specifically, increased reporting of child abuse and neglect, elevated infant mortality, poor quality of life, and worse ranking in years of potential life lost. Counties with persistent poverty had lower rates of dental utilization. CONCLUSIONS: Utilization of dental services in the MPW program is generally low. Patterns identify the potential for enhancing community-clinical linkages to improve birth outcomes and care coordination for pregnant women to enhance dental utilization in this population. Dental coverage in the Medicaid program in most states is administered separately from medical coverage. The separation of the funding mechanisms adds a further layer of complexity to care integration. Efforts to enhance dental care for pregnant women in the Medicaid program may benefit from policy that aligns incentives for care coordination within the community. Policy that extends the window of eligibility for dental benefits to 24 months after the birth of the child will help women complete the dental treatment that is needed. This also leverages the value of care coordination for community stakeholders from diverse child health sectors.

A Technical Assistance Curriculum for Expanding Sustainable School-Based Oral Health Programs in the Carolinas' Dental Safety Net.

PURPOSE: School-based oral health programs (SBOHPs) provide opportunities to address oral health inequities by providing convenient access points for care. No published guidelines on SBOHP implementation existed. Our work describes how philanthropic, public, and academic organizations partnered to support dental safety net providers with designing comprehensive SBOHPs in North and South Carolina. DESCRIPTION: A multi-sector leadership team was established to manage a new SBOHP philanthropic-funded grant program organized into two phases, Readiness and Implementation, with the former a 6-month planning period in preparation of the latter. Readiness included technical assistance (TA) delivered through coaching and 15 online learning modules organized in four domains: operations, finance, enabling services, and impact. Organizations could apply for implementation grants after successful TA completion. Process evaluation was used including a Readiness Stoplight Report for tracking progression. ASSESSMENT: Ten Readiness grantees completed the TA. A variety of models resulted, including mobile, portable and fixed clinics. Descriptive analysis was conducted on the readiness stoplight reports. Components of the operation and finance domains required were the most time-intensive, specifically the development of policy manuals, production goals, and financial performance tracking. CONCLUSION: The program's structure resulted in (a) a two-state learning community, (b) SBOHP practice and policy alignment, and (c) coordinated program distribution. TA improvements are planned to account for COVID-19 threats, including school closures, space limitations, and transmission fears. Telehealth, non-aerosolizing procedures, and improved scheduling and communication can address concerns. Organizations considering SBOHPs should explore similar recommendations to navigate adverse circumstances.

Improving predoctoral education related to caries risk assessment in adults.

OBJECTIVES: This project examined patterns of adult patient management using a caries risk assessment (CRA) protocol at East Carolina University, School of Dental Medicine. Usage of the CRA protocol from 2014 to 2019 was assessed. Non-operative anti-caries treatments were measured against caries risk status (high, moderate, low, or none). Steps to improve the appropriate management of patients based on caries risk are presented to align with accreditation standards for predoctoral education programs. METHODS: The CRA protocol is based on the Caries Management by Risk Assessment approach. Risk-based patterns for two non-operative interventions were examined: (1) prescriptions for 0.12% chlorhexidine gluconate (CHX) mouth rinse and (2) prescriptions for 5000 ppm fluoride toothpaste (PreviDent 5000 [PreviDent]). Statistical analyses included chi-square tests and logistic regression. RESULTS: Over the study period only 16.4% of adult patients had completed the CRA form. Among 29,411 patients from nine community sites, treatment rates for PreviDent were 18.7% among high-risk patients, 11.6% for moderate-risk adults, and 6.4% for low-risk adults (p < 0.01). Treatment rates for CHX were 23.0%, 22.6%, and 17.1%, respectively (p < 0.05). Patients without a CRA status were least likely to receive any anti-caries treatments, indicating that CRA status affects clinical, non-operative care. CONCLUSIONS: Patterns for prescription of PreviDent and CHX are consistent with CRA status. Future efforts to improve usage of the CRA protocol using faculty calibration, tracking with quality improvement tools, and reassessment. Training in the community-based educational setting is enhanced through data-based tracking to assure evidence-based decision making.

Dental Caries and Preventive Dental Visits Among Children in the U.S.: The Impact of Race/Ethnicity and Immigration.

Introduction: National data on dental caries and dental service use among immigrant children in U.S. are limited. It is not known whether race/ethnicity would interact with immigration status to increase these disparities. Using a nationally representative sample, this study assessed the interaction effects of immigrant generation status and race/ethnicity on dental caries and dental visits among children in the U.S. Methods: Data were from the 2020 and 2021 National Survey of Children's Health. All data were self-reported by parents/guardians. The 2 outcomes were (1) dental caries (yes/no) in the past 12 months and (2) preventive dental visits (yes/no) in the past 12 months. Racial/ethnic groups included non-Hispanic White, Black, Hispanics, and Asian Americans. The analytical sample included 66,167 children aged 2-17 years, including 1,243 first-generation immigrant children; 11,017 second-generation immigrant children; and 53,907 nonimmigrant children. Study authors ran separate multiple logistic regression models for the 2 outcome variables. All analyses accounted for the survey design of National Survey of Children's Health. Results: First-generation immigrant children were more likely to have dental caries than nonimmigrant children (AOR=1.44). The interaction of race/ethnicity and immigrant generation status was significant (p=0.04) in the preventive dental visits model, indicating increased challenges in getting dental visits among minority immigrant children in comparison with that among non-Hispanic White immigrant children, especially among first-generation immigrant children of Asian Americans (AOR=0.41) and non-Hispanic Black immigrant children (AOR=0.37). Conclusions: First-generation immigrant children were less likely to see a dentist and more likely to have dental caries than nonimmigrants. Moreover, first-generation immigrant children from minority racial/ethnic groups were the least likely to seek dental services. To further reduce disparities in oral health and dental use among children in the U.S., culturally sensitive health promotion is warranted to improve oral health literacy and reduce barriers to dental care for immigrants, especially immigrant children of the minority groups.

Trends in dental visits among US adults from 1997 through 2019: Implications for policy reform.

BACKGROUND: Examination of serial cross-sectional national surveys from a representative sample of the population can identify patterns and help support policy development. METHODS: The authors used data from the National Health Interview Survey on US adults reporting a dental visit in the past 12 months to examine trends from 1997 through 2019. Groups analyzed were based on sociodemographic factors including residence in a metropolitan statistical area, race and ethnicity, family income level, and geographic region. RESULTS: Over the 23-year period, the authors found differences for family income level, living in a rural (nonmetropolitan vs metropolitan) area, race and ethnicity, and geographic region (P < .0001). When stratified by family income, racial disparities have diminished. Gaps in dental service use are long-standing for rural nonmetropolitan communities. CONCLUSIONS: Relative to urban locales, rural communities experienced persistent disparities in the use of the oral health care delivery system throughout the 23 years measured. Strategies to create innovative models of care are needed to address oral health needs in underserved rural communities. PRACTICAL IMPLICATIONS: Policy is needed to foster a shift toward population health that will incentivize a health care system that reduces financial barriers and enhances health outcomes for adult oral health, especially for rural areas.

The most common types of nontraumatic dental conditions among emergency department visits in North Carolina before and during the COVID-19 pandemic.

BACKGROUND: This study aimed to identify the most common types of nontraumatic dental conditions (NTDCs) before and during the COVID-19 pandemic and assess the variations in the most common NTDCs by patient age groups and rural or urban locations and the impact of COVID-19 on emergency department (ED) visits for NTDCs in North Carolina. METHODS: The authors conducted a retrospective data analysis of ED data from the North Carolina Disease Event Tracking and Epidemiology Collection Tool. The authors estimated the proportions of NTDCs of all ED visits in 2019 and 2021 and ranked the proportions of the major categories of NTDCs by age groups and rural or urban locations. They used a multiple logistic regression model to assess the impact of COVID-19 on NTDCs. RESULTS: By the first diagnosis, the proportion of NTDCs dropped from 1.1% in 2019 to 0.99% in 2021 (P < .001). Caries was specified as the third most common NTDC. Oral infection was the top NTDC among young (≤ 17 years) and older patients (≥ 65 years). No significant differences were found in NTDCs between rural and urban areas (P = .68). Children younger than 2 years (adjusted odds ratio, 4.36) and adults aged 18 through 44 years (adjusted odds ratio, 4.54) were more likely to visit the ED for NTDCs than those 75 years and older. CONCLUSIONS: The proportion of NTDCs seen at the ED was lower during the COVID-19 pandemic in 2021 than in 2019. The common NTDCs varied by age group but were similar in rural and urban areas. The most common NTDCs were related to toothache, oral infection, and caries. PRACTICAL IMPLICATIONS: More efforts are needed to reduce ED visits for NTDCs.

Rural-Urban Differences in Use of Dental Services and Procedures Among Medicare Beneficiaries in 2018.

OBJECTIVE: Medicare beneficiaries in rural areas may face challenges in access to dental care. This study assessed rural-urban differences in the use of dental services and dental procedures by Medicare beneficiaries. METHODS: We obtained data from the 2018 Medicare Current Beneficiary Survey cost and use files. Outcome variables examined in this study were (1) dental visits (yes/no), whether the Medicare beneficiary had ≥1 dental visit in the past year, and (2) dental procedures-preventive (yes/no), restorative (yes/no), and surgical procedures (yes/no)-whether the beneficiary had the procedure in a dental visit. The independent variable was the beneficiary's residence (rural vs urban). We used multiple logistic regression to analyze data and accounted for the survey design of the Medicare Current Beneficiary Survey. The analytic sample included 7377 respondents aged ≥65 years. RESULTS: Approximately 57.0% (95% CI, 54.9%-59.0%) and 46.4% (95% CI, 41.6%-51.2%) of Medicare beneficiaries in urban and rural communities in the United States had a dental visit in 2018, respectively. Rural beneficiaries were significantly less likely than their urban counterparts to have preventive procedures (adjusted odds ratio = 0.51; 95% CI, 0.36-0.72) but significantly more likely to have restorative procedures (adjusted odds ratio = 1.30; 95% CI, 1.05-1.62). CONCLUSION: We found significant disparities in use of dental services by Medicare beneficiaries in rural communities. When Medicare beneficiaries in rural areas used dental care, they were less likely than beneficiaries in urban areas to have preventive procedures but more likely to have restorative procedures, suggesting a greater burden of oral health needs among them. Policy research is needed to identify models that can incentivize prevention and improve access to dental care for Medicare beneficiaries in rural communities.

Racial/ethnic disparities in preventive dental services use and dental caries among children.

OBJECTIVE: To assess disparities in preventive dental service use in four major racial/ethnic groups and assess whether racial/ethnic and income-related disparities among children were reduced from 2016 to 2020. METHODS: Data were from the 2016 and 2020 National Survey of Children's Health (NSCH). The outcomes of interest were having dental sealants, fluoride treatment, and dental caries in the past 12 months. Racial/ethnic groups included non-Hispanic (NH) whites, blacks, Hispanics, Asians, and others. Family income level was categorized as below or above the 200% federal poverty level (low-income vs. high-income). Children ages 2-17 were included (N = 161,539). All data were self-reported by parents/guardians. We estimated the trends of racial/ethnic disparities in having fluoride treatment, dental sealants, and dental caries from 2016 to 2020 and tested two 2-way interactions (i.e., year by race/ethnicity, year by income) and one 3-way interaction (year by income by race/ethnicity) to assess the change in disparities from 2016 to 2020. RESULTS: Overall, no significant trends in receipt of fluoride treatment, dental sealants, or having dental caries were found from 2016 to 2020 among the racial/ethnic groups, except for a decreasing trend in dental sealants for Asian American children (p = 0.03). Overall, NH white children were more likely to have received preventive dental services than children from minority groups (all p < 0.05); Asian American children (AOR = 1.31) were more likely to have dental caries than NH white children. CONCLUSION: Disparities in receipt of evidence-based preventive services by children persisted. Continuous efforts are needed to promote the use of preventive dental services among children of minority populations.

The use of teledentistry in clinical oral and maxillofacial pathology practice: an institutional experience.

Background: Although there has been a slight increase in dental professionals since 2011, 98 of North Carolina's 100 counties are designated as Dental Health Professional Shortage Areas by the Heath Resources and Service Administration. This shortage significantly increases disparities and access to primary and specialized oral health care. Also, dental professionals in these remote locations may feel the access and referrals to oral and maxillofacial pathologists cumbersome. In 2020, the COVID-19 pandemic prompted an inevitable surge in the use of digital technology due to the social distancing norms and lockdowns, which forced dental education institutions and practitioners to adjust to new ways of meeting, teaching, and providing dental care. In the present manuscript, we report our institutional experience delivering specialized dental care in rural areas. Materials and methods: We conducted a retrospective case series of diagnosis, management, and outcomes of patients who underwent synchronous or asynchronous virtual and remote examination of oral lesions at ECU School of Dental Medicine and one satellite clinic over seven years. For those cases that concluded on surgical sampling, the clinical impressions, differential diagnoses, and the final diagnosis were compared to assess the accuracy of the clinical exam through teledentistry. Results: The total study population consisted of 71 patients. Most of the remote consultations were done asynchronously. Also, most virtual clinical consultations were initiated due to clinical suspicion of malignancy and infectious/reactive conditions, accounting for 42% and 25.3% of all encounters. Conclusions: The presented data suggest how teledentistry can support clinical practice in rural areas to achieve optimal care for the patient in rural or remote communities. Also, it significantly decreases the travel required, the number of appointments, and increases the speed of diagnosis. Teledentistry is an excellent tool available to all clinicians and can dramatically aid in diagnosing oral mucosa lesions.

Racial and ethnic disparities in periodontal health among adults seeking dental care in rural North Carolina communities: A retrospective study.

BACKGROUND: Population studies consistently demonstrate a greater prevalence of chronic diseases, including oral diseases, among underrepresented minorities. This retrospective study aimed to measure and describe the prevalence and extent of periodontitis among adults seeking dental care within an academic practice-based network in rural North Carolina. METHODS: This study used de-identified electronic health record (EHR) data from 2011 to 2017 of adult dentate patients (aged ≥30 years) seeking dental care who received a comprehensive periodontal examination at one of nine networked clinical centers. Periodontitis prevalence was calculated using CDC/AAP case definitions, along with extent (%) scores for periodontal parameters. Comparisons focused on age, sex, race, ethnicity, tobacco use, diabetes status, payer or insurance status, plaque scores, and the number of teeth. RESULTS: EHR data for 10,544 adult patients (60.5% female) indicated 79.8% had some form of periodontitis. This patient population was diverse: 22.6% Black, 4.4% American Indian, and 53.8% White, with 4.8% self-identified as Hispanic. Patients 50 years and older showed greater mean extent scores for clinical attachment levels relative to patients 30 to 49 years. Males exhibited greater periodontitis than females (p = 0.001). Blacks showed significantly (p < 0.001) greater periodontitis prevalence relative to Whites. Hispanics also showed a greater prevalence of periodontitis (p < 0.001) relative to non-Hispanics. Significantly greater periodontitis was also noted for tobacco users (p < 0.001) but not for diabetes or payer status. A multiple logistic regression analysis of periodontitis prevalence confirmed significant associations for periodontitis for age, sex, race, ethnicity, tobacco use, high plaque scores, and the number of teeth (p < 0.001), but not diabetes or payer status. CONCLUSIONS: The data document that racial and ethnic inequalities in periodontal health occur within the population of adults residing in rural communities in North Carolina and seeking dental care.

High sugar intake from sugar-sweetened beverages is associated with prevalence of untreated decay in US adults: NHANES 2013-2016.

OBJECTIVES: To assess the association between sugar from sugar-sweetened beverages (SSBs) and untreated decay in permanent teeth and calculate the cost burden of sugar from SSBs on untreated decay in US adults. METHODS: Cross-sectional data from the 2013-2014 and 2015-2016 cycles of the National Health and Nutrition Examination Survey (NHANES) were analysed in 2020 (n = 9001 adults aged ≥20). Multivariable analyses assessed sugar intake from SSB consumption with the presence of untreated decay in permanent teeth and number of untreated decayed teeth. Population attributable risk was used to estimate the cost burden arising from SSBs on untreated decay in US adults. RESULTS: One fourth (25.1%) of US adults had untreated dental decay, and higher prevalence was observed among those with low income, low education and race/ethnicity of non-Hispanic Black. Overall, 53% of adults reported no intake of SSBs. For the remaining 47%, the median 24-h intake was 46.8 g of sugar from SSBs. The adjusted prevalence ratio (PR) for untreated decay was 1.3 (95% confidence interval [CI] 1.1-1.5) for consumption of 46.8 g or more of sugar from SSBs compared to those reporting no sugar from SSBs. Number of untreated decayed teeth increased with sugar intake from SSBs from lowest to highest tertile: 0.1, (p = .35); 0.4, (p = .006); and 0.6, (p < .001). The cost burden of untreated decay attributable to SSBs in US adults is estimated conservatively at $1.6 billion USD. CONCLUSIONS: Community level interventions directed at sugar from SSBs are justified to address disparities in the burden of untreated dental decay.

Rural-Urban Differences in Dental Service Utilization and Dental Service Procedures Received Among US Adults: Results From the 2016 Medical Expenditure Panel Survey.

PURPOSE: To assess rural-urban differences in dental service use and procedures and to explore the interaction effects of individual- and county-level factors on having dental service use and procedures. METHODS: Data were from the 2016 Medical Expenditure Panel Survey (MEPS). We assessed rural-urban differences in 3 outcome variables: number of dental visits (1, 2, or 3+ visits), preventive care procedures (Yes/No), and treatment procedures (Yes/No). The study sample included 8,199 adults ≥ 18 years of age who reported at least 1 dental visit in the past year. Sampling weights embedded in MEPS were incorporated into all the analyses. FINDINGS: A significant interaction between residential location and race/ethnicity (P = .030) suggested limited access to dental visits for minority groups, especially for blacks in the more rural areas. Adults from a more rural area were less likely to have received a preventive procedure (AOR = 0.55, 95% CI: 0.35-0.87) than those from an urban area. Adults of racial/ethnic minority groups, with lower SES, and without dental insurance were less likely to have received a preventive procedure (all P < .01) but were more likely to have received a treatment procedure (all P < .05). CONCLUSIONS: The study showed rural adults were less likely to have received preventive dental procedures than their urban counterparts. Racial/ethnic minority groups living in a more rural area had even more limited access to dental services. Innovative service delivery models that integrate telehealth and community-based case management may contribute to addressing these gaps in rural communities.

Risk Indicators of Urgent and Extensive Dental Treatment Needs in U.S. Air Force Recruits.

INTRODUCTION: Dental Readiness Classifications (DRCs) enable the Military Health System to prioritize dental care in garrison, minimizing dental emergencies and mission degradation during deployments. Over half (52.4%) of 2008 military recruits presented with high-priority urgent needs classified as DRC3 upon initial dental examination and 18.1% required extensive treatment, needing 7 or more restorations, in order to achieve operational dental readiness. The purpose of this study is to identify risk indicators for urgent and extensive dental treatment needs in current U.S. Air Force (USAF) recruits so that Dental Corps leadership can target interventions to maximize oral health, prioritize resources, and reduce health expenditures in this patient population. MATERIALS AND METHODS: A secondary data analysis was performed of deidentified survey and clinical exam data from the 2018 to 2019 USAF Recruit Oral Health Surveillance study conducted at Lackland Air Force Base from February 2018 to February 2019. Select demographic and self-reported variables were analyzed with two outcome variables: urgent (DRC3) and urgent and extensive (DRC3 + 7) dental treatment needs. Univariate log binomial regression was performed to determine relative risk of DRC3 and DRC3 + 7 by independent variable. The Uniformed Services University of the Health Sciences institutional review board approved the study as an exempt protocol. RESULTS: Among the 1,335 recruits studied, the overall prevalence of urgent dental needs was 21.5%, whereas 5.5% of participants had both urgent and extensive needs. The study group included participants who were mostly male (69%), were non-Hispanic white (60%), aged 17 to 19 years (48%), were high school educated (47%), had private dental insurance coverage (50%) and self-reported: no need for dental care in the past year (65%), excellent or good condition of teeth (63%), were toothbrushing more than once a day (58%), and had daily consumption of one to three servings of sugary beverages (62%) and foods (69%). Statistically significant differences in relative risk for DRC3 were found for all independent variables except gender and education level. Risk indicators significant for DRC3 and DRC3 + 7 were aged 25 to 29 years; Other and Black race/ethnicity; Medicaid insurance; uninsured; self-reported fair, poor, or unsure current condition of teeth; and past year needed care but did not go (P < .05). The majority of DRC3 and DRC3 + 7 cases were in the small subset of recruits who self-reported fair, poor, or unknown current condition of teeth or need for dental care in the past year without a dental visit. CONCLUSIONS: Among USAF recruits, oral health disparities are observed in certain groups. The study findings can inform targeted utilization of resources and interventions to efficiently optimize oral health and operational dental readiness and decrease dental expenditures. Additionally, a two-question screening tool is proposed to facilitate priority assignment for dental examination during boot camp. This tool has the potential to correctly identify nearly 90% of those with urgent and extensive dental treatment needs at half the typical workload.

Collaborating and teaching a synchronous, multi-university, virtual course: Health policy and access to dental care.

PURPOSE: In response to COVID-19, dental educators have been tasked with maintaining the quality of education while reducing cost, increasing efficiency, and leveraging technology. METHODS: This collaborative, multisite virtual health policy course used the Staged Self-Directed Learning Model (SSDL) to lead a diverse group of students studying health policy. Twelve Core sessions were offered with three additional sessions in August or December for a total of 15 total synchronous Zoom sessions that covered policy issues on supply, demand, and need for dental care. RESULTS: Twenty-eight students, seven lead instructors, and two course directors from six schools reported positive feedback on the course format, use of technology and the SSDL model, and breadth of topics presented. Participation by universities in four states with differing health policies stimulated virtual classroom discussions. CONCLUSION: In conclusion, collaborative interinstitutional virtual teaching and learning is cost effective, efficient, and engaging for students. This model has the potential to continue even when institutions are no longer affected by COVID-19.

Trends of children being given advice for dental checkups and having a dental visit in the United States: 2001-2016.

INTRODUCTION: The objectives of this study were to describe trends of children being given dental checkup advice by primary care providers (PCPs) and having dental visits and to assess factors associated with being given dental checkup advice and having a dental visit. METHODS: Data were from the annual, cross-sectional Medical Expenditure Panel Survey (MEPS) from 2001 to 2016. The sample included 126,773 children ages 2-17 years. We used predictive margins to estimate the probability of being given dental checkup advice and having a dental visit. We examined time trends of the proportion of children being given dental checkup advice from PCPs, as well as trends in the proportion of children having a dental visit from 2001 to 2016. Multiple logistic regression was used to assess the association between being given dental checkup advice and having a dental visit. RESULTS: Overall, the proportion of children being given dental checkup advice increased from 31.4% in 2001 to 51.8% in 2016 (Trend P < 0.001). No significant increasing trend was found for having a dental visit among those being given dental checkup advice (Trend P > 0.05). Children being given dental checkup advice were more likely to have a dental visit (AOR = 1.54, P < 0.001). CONCLUSIONS: Although there was an increase in the proportion of children being given advice to have dental checkups by PCPs from 2001 to 2016, there was no significant increase in having a dental visit among children being given the advice. More research is needed to better understand how dental care advice from a PCP can effectively motivate and facilitate dental care for children.

Fluorides in dental public health programs.

The use of fluorides in dental public health programs has a long history. With the availability of fluoridation and other forms of fluorides, dental caries have declined dramatically in the United States. This article reviews some of the ways fluorides are used in public health programs and discusses issues related to their effectiveness, cost, and policy.

The influence of drill wear on cutting efficiency and heat production during osteotomy preparation for dental implants: a study of drill durability.

PURPOSE: The authors evaluated, under conditions simulating implant placement, the cutting efficiency, durability, heat production, and wear of implant drills. MATERIALS AND METHODS: Osteotomies were performed on bovine ribs using a surgical unit mounted in a testing apparatus. A software program controlled the apparatus and recorded temperatures, depths, and drilling times. Seven brands of drills were tested (Nobel Biocare, 3i/Implant Innovations, Steri-Oss, Paragon, Implamed, Lifecore, and ITI). Spade, twist, tri-flute, and TiN-coated drill designs were evaluated and compared during 100 successive osteotomies. Scanning electron microscopic and energy-dispersive x-ray spectroscopic examinations were performed, and hardness was measured. RESULTS: Two 2-mm drills (Nobel Biocare and 3i/Implant Innovations) had mean removal rates significantly greater than the others (P < .05). The 2-mm twist drill design with a low hardness (Implamed) exhibited plastic deformation at the cutting edge, loss of cutting efficiency, and drill fracture. The TiN-coated drills (Steri-Oss and Paragon) showed greater wear and significantly lower removal rates (P < .05) than noncoated drills. Temperature increases with different drills were not significantly different at depths of 5 or 15 mm or between 2-mm or 3-mm drills. With 1 exception (the 2.3-mm Paragon drill at a depth of 15 mm), the temperatures generated by the different types of drills were not significantly different. Clinically harmful temperatures were detected only at a depth of 15 mm during 5 osteotomies and coincided with a marked decrease in the rate of drill advancement with a resulting continuous drilling action. DISCUSSION: Temperatures generated at depths of 5 and 15 mm by the different drill types and diameters were not significantly different and, with only 5 exceptions, were clinically safe. Several differences between brands were noted in regard to cutting efficiency and durability, underscoring the importance of material selection and quality on drill performance. CONCLUSIONS: Drill design, material, and mechanical properties significantly affect cutting efficiency and durability. Coolant availability and temperature were the predominant factors in determining bone temperatures. Implant drills can be used several times without resulting in bone temperatures that are potentially harmful. Continuous drilling in deep osteotomies can produce local temperatures that might be harmful to the bone.
