Abstract 998: Pursuing leadership in literacy to ameliorate head and neck cancer disparities

Abstract Overview of Proposed Research. Head and neck cancers are a deadly cancer that ranks among the six most common cancers worldwide. (American Cancer Society, 2021). Studies have shown greater disease burden among minority populations for head and neck cancer, higher mortality rates and lower oral cancer knowledge, but limited evidence has defined the underlying causes of late stage diagnoses and access to the healthcare system (Suzuki et al, 2019). More specifically, in comparison to the national rates, South Carolina is among the top ten for head and neck cancers (Community Outreach, Hollings Cancer Center, MUSC, 2019). Dental and primary care play a critical role delivering quality patient education, prevention, risk reduction and treatment regimes. However, there is a paucity of information published on the value of designing and implementing a health literacy program to prioritize head and neck cancer screening and prevention. Rural communities face unique challenges to achieving optimal oral health, impacted mainly by geographic location and socioeconomic status (IOM&NRC, 2011). More specifically, rural southern states such as SC continues to have a tremendous shortage of primary care providers. SC currently has 44 of 46 counties designated as geographic Primary Care and Dental Health Professional Shortage Areas and approximately 25% of SC citizenry are living in rural areas (HRSA, 2018). Because the vast majority of the state has challenges with availability of primary care and dental providers, this potentially exacerbates access to care inequities for rural and underserved minority populations. To enhance the quality and equity of oral cancer prevention in rural SC, it is critical that we prioritize strategies to elevate the significance of head and neck cancer risks. Therefore, the need to design and deliver innovative strategies to increase opportunities that intersect the healthcare system and community is inevitable. In this regard, we propose PULL A-HEAD, Pursuing Leadership in Literacy to Ameliorate HEAd and neck cancer Disparities. PULL A-HEAD is aimed to develop and implement a community-centered approach design for increasing the health literacy and efficacy of navigating the healthcare system for early detection of head and neck cancers. In this presentation we will share outcome and impact results of a community-centered, health literacy program in collaboration with our Regional Medical Library - Region 2 (RML2), National Library of Medicine partners at the Medical University of South Carolina. The program (i.e. PULL A-HEAD) will emphasize the delivery of health literacy education and health systems navigation tools to improve the early detection of head and neck cancers.

Disseminating oral health educational content and evaluating its use on non-dental safety net clinic websites.

Safety net clinics (SNC) provide healthcare to vulnerable populations and SNC websites are an important information source. In North Carolina (NC), all 100 counties are Dental Health Professional Shortage Areas, yet 91 of 317 SNCs are non-dental (ND-SNC). Our goals were to: (1) assess the presence and type of oral health (OH) information on ND-SNC websites; (2) develop and distribute an OH education webpage to ND-SNCs and track its use. The website search function was used with common dental terms to evaluate the presence of OH content on each ND-SNC website. Key representatives from ND-SNCs were surveyed to assess patient care and willingness to implement an OH webpage. Webpage topics included oral hygiene and a map of NC dentists that provide services to low-income patients. Google Analytics was used to track consumer webpage engagement including acquisition source (AS), average time on page (AT), and unique page views (UPV). Of the 91 ND-SNCs websites, none contained OH education; 15% had information about nearby dental providers. For the 40 ND-SNCs using our webpage, January-December 2022, the primary AS for new webpage users was referrals; 72.5% of users visited directly from ND-SNC websites. Statewide AT was 2 min and 30 s (SD = 58 s), 2.88 times longer than the 52-s threshold marketing experts use to establish genuine user engagement. There were 1364 UPVs statewide for 2022. Our results suggest a need for OH education content on ND-SNC websites, as users are searching for and engaging with this information.

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

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. 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. 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. 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.

Cost-effectiveness of Dental Workforce Expansion Through the National Health Service Corps and Its Association With Oral Health Outcomes Among US Children

Despite considerable efforts to improve oral health for all, large disparities remain among US children. A dental professional shortage is thought to be among the determinants associated with oral health disparities, particularly for those residing in underserved communities. To evaluate the cost-effectiveness of expanding the dental workforce through the National Health Service Corps (NHSC) and associations with oral health outcomes among US children. A cost-effectiveness analysis was conducted to estimate changes in total costs and quality-adjusted life years (QALYs) produced by increasing the NHSC funding for dental practitioners by 5% to 30% during a 10-year period. A microsimulation model of oral health outcomes using a decision analytic framework was constructed based on oral health and dental care utilization data of US children from 0 to 19 years old. Data from the nationally representative National Health and Nutrition Examination Survey (NHANES, 2011-2016) were linked to county-level dentist supply and oral health professional shortage areas (HPSAs) information. Changes in prevalence and cumulative incidence of dental caries were also estimated. Sensitivity analyses were conducted to assess the robustness of results to variation in model input parameters. Data analysis was conducted from August 1, 2021, to November 1, 2022. Expanding dental workforce through the NHSC program. Changes in total QALYs, costs, and dental caries prevalence and cumulative incidence. This simulation model informed by NHANES data of 10 780 participants (mean [SD] age, 9.6 [0.1] years; 5326 [48.8%] female; 3337 [weighted percentage, 57.9%] non-Hispanic White individuals) found that when funding for the NHSC program increased by 10%, dental caries prevalence and total number of decayed teeth were estimated to decrease by 0.91 (95% CI, 0.82-1.00) percentage points and by 0.70 (95% CI, 0.62-0.79) million cases, respectively. When funding for the NHSC program increased between 5% and 30%, the estimated decreases in number of decayed teeth ranged from 0.35 (95% CI, 0.27-0.44) to 2.11 (95% CI, 2.03-2.20) million cases, total QALY gains ranged from 75.76 (95% CI, 59.44-92.08) to 450.50 (95% CI, 434.30-466.69) thousand QALYs, and total cost savings ranged from $105.53 (95% CI, $70.14-$140.83) to $508.23 (95% CI, $598.91-$669.22) million among children residing in dental HPSAs from a health care perspective. Benefits of the intervention accrued most substantially among Hispanic children and children in low-income households. This cost-effectiveness analysis using a decision analytic model suggests that expanding the dental workforce through the NHSC program would be associated with cost savings and a reduced risk of dental caries among children living in HPSAs.

Participation in the CARES Act Provider Relief Fund policy by dentists in South Carolina's safety net.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act appropriated $100billion to the Provider Relief Fund, allowing for direct payments to health care providers due to COVID-19. Few studies have evaluated participation in the Provider Relief Fund (PRF), and none have specifically looked at dental providers in the safety net. We conducted a retrospective, secondary data analysis using a quasi-experimental cohort design of South Carolina dentists who received PRF payments, comparing those who did and did not participate in the safety net. Safety net practice was operationalized as those participating in Medicaid, and whether they provided care in dental health professional shortage areas, or rural communities. Of the 628 dental providers in South Carolina who received PRF payments, 34% were identified as Medicaid providers while 66% did not participate in Medicaid; we found no statistical difference between payments to Medicaid versus non-Medicaid dental providers. Of PRF payments to dental providers participating in South Carolina's Medicaid program, we found no difference between payments to rural and urban providers but did find that practices offering services in dental care shortage areas received less than providers practicing in counties not designated as a shortage area. The PRF achieved its goal of distributing financial support to providers affected by the COVID-19 pandemic. But without policy imperatives linked to need-based allocations or incentives for PRF recipients to serve safety net populations, we may later learn this was a missed opportunity for PRF.

Opioid Prescriptions Prior to Emergency Department Dental Visits: A Comparison of Dental Health Professional Shortage Areas (DPSAs) and Non-DPSAs Using Electronic Health Records.

Although prior research has linked dental conditions and opioid prescribing in the U.S., it is not yet known whether the receipt of opioid prescriptions prior to seeking emergency care for dental conditions differs in geographical areas that are underserved by health care professionals (Dental Professional Shortage Areas, DPSAs) compared to other areas. Using Indiana's state-wide electronic health records from January 1, 2016 to October 31, 2020, we examine if patients from DPSAs presenting at the emergency department (ED) for dental conditions are more likely to have received opioid prescriptions in the 30 days prior to their visit, compared to patients from other areas. A higher rate of opioid receipt among DPSA individuals may indicate an association between lower availability of dental professionals and the use of opioids as a coping strategy. We note that our study design has several limitations (such as a lack of data on prescription use after the ED visit) and does not prove causation. We find that individuals experiencing dental condition ED visits in DPSAs are 16% more likely (than those in non-DPSAs) to have filled an opioid prescription in the 30 days prior to the ED visit, after controlling for age, gender, and race/ethnicity. This result is statistically significant at the 1% level. The baseline rate of opioid filling in the 30 days prior to the ED visit is 12% in DPSAs. These correlational results suggest that unmet dental needs might be substantially connected to opioid prescriptions, although further research is needed to establish whether this relationship is causal.

Qualitative evaluation of the pre-implementation phase of a rural dental clinic co-located within a health center in the Pacific Northwest of the United States.

The development of a dental clinic within an existing Rural Health Clinic (RHC) was proposed to improve access to dental care for Medicaid enrollees in Washington. This qualitative study assessed the implementation of a co-located dental clinic in a rural community during the pre-implementation phase. Additionally, we sought to determine the needs and expectations of community members living in this rural Washington county. This study took place in Jefferson County, Washington, aDental Health Professional Shortage Area.Semi-structured interviews were conducted with 42 participants, consisting of administrators (n=9), health providers (n=9) and community members (n=24). Administrators and health providers were interviewed by phone. Community members were interviewed in-person at Jefferson Healthcare primary care clinics or by phone. Interview data were deductively coded, and thematic analysis with a hybrid inductive-deductive approach was used to analyse coded data. Five themes were identified regarding local needs and expectations: dental care as a major need in the community, persisting barriers to dental care access, expecting more than a 'Medicaid experience', visions for a clinic that serves the community, and solutions outside the clinic to improve community oral health. By improving access to dental care, a co-located dental clinic is helping to address general dental care needs in rural communities. Policy-level solutions that address housing and food insecurity, improve public transportation, and retain and expand low-income adult Medicaid dental benefits may be needed to overcome persisting barriers to oral health.

Evaluating access to pediatric oral health care in the southeastern states

BackgroundIn this article, the authors addressed shortcomings in existing research on pediatric oral health care access using rigorous data and methods for identifying statistically significant disparities in oral health care access for children. MethodsThe study population included children, differentiated by insurance status (Medicaid, Children’s Health Insurance Program, private, none). The authors measured provider-level supply as the number of oral health care visits, stratified by provider type and urbanicity-rurality. The authors defined demand as the number of dental visits for children and derived demand and supply mainly from 2019 and 2020 data. Using statistical modeling, the authors evaluated where disparities in travel distance across communities or by insurance status were statistically significant. ResultsAlthough Dental Health Professional Shortage Areas are primarily rural, this study found that the proportions of rural, suburban, and urban communities identified for access interventions ranged from 24% through 66% and from 8% through 86%, respectively. For some states (Florida, Louisiana, Texas), rural and suburban communities showed a need for interventions for all children, whereas in the remaining states, the lack of Medicaid and Children’s Health Insurance Program access mainly contributed to these disparities. Variations in access disparities with respect to insurance status across states or by urbanicity-rurality were extensive, with the rate of communities identified for reducing disparities ranging from 1% through 100%. ConclusionsAll states showed a need for access interventions and for reducing disparities due to geographic location or insurance status. The sources of disparities were different across states, suggesting need for different policies and interventions across the 10 states. Practical ImplicationsThe study findings support the need for policies toward reducing disparities in oral health care access.

Geographic variations in dental sealant utilization by Medicaid enrollees.

To investigate geographical variations and their relationship to race/ethnicity in dental sealant utilization for first molars among Wisconsin Medicaid enrollees from 2010 to 2013. Wisconsin Medicaid dental claims for sealants in children aged 6-16 years were analyzed. County-level population density, urban influence code, presence of dental health professional shortage areas, and population-per-dentist ratio were considered as geographic predictors. Descriptive statistics and mixed effects Poisson regression models were used to examine the effect of county level covariates on the number of dental sealants received per person-year (PY) of eligibility adjusting for patient-level characteristics. Over-dispersion was modeled by a random residual effect, and all models adjusted for single-year age and gender interaction and race/ethnicity main effect. Medicaid claims for sealants on first permanent molars for 2010-2013 totaled 288,019 over 1,130,000 PY. The age- and gender-standardized rate of first molar sealant applications per 100 PY were 27.9, 25.7, and 16.6 for White, Hispanic, and Black children, respectively. County-specific rates ranged from a low of 8.9 per 100 PY to a high of 62.6 per 100 PY. In the multivariate analysis after adjusting for geography, compared to Whites, Hispanics had highest rates (rate ratio (RR)=1.33, 95% CI=1.30-1.37) of dental sealant utilization followed by Blacks (RR=1.25, 95% CI=1.21-1.29). Population density was the only significant geographic predictor (RR=0.56 per 10-fold increase, 95% CI=0.45-0.69). Substantial geographic variability in the utilization of sealants for first molars was identified. Lower population density was the main geographical predictor of high sealant utilization.

The Impact of Title VII Dental Workforce Programs on Dentists' Practice Location: A Difference-in-Differences Analysis.

To examine the potential impact of Health Resources and Services Administration (HRSA) funding (predoctoral [PD] and postdoctoral [PDD] programs) on dentists' practice location in the United States. The authors linked 2011-2015 data from HRSA's Electronic Handbooks to 2015 data from the American Dental Association Masterfile, dental health professional shortage areas, and rural-urban commuting area codes. They examined the associations between PD and PDD funding and dentists' practice location between 2004 and 2015 using a difference-in-differences analysis and multiple logistic regressions, adjusting for covariates. From 2004 to 2015, 21.2% (1,588/7,506) of dentists graduated from institutions receiving PD funding and 26.8% (2,014/7,506) graduated from institutions receiving PDD funding. Among dentists graduating from institutions receiving PDD funding, after adjusting for covariates, those graduating between 2011 and 2015 were more likely to practice in a rural area than those graduating between 2004 and 2010 (odds ratio [OR] = 1.98; 95% confidence interval [CI] = 1.04-3.76). The difference-in-differences approach showed that PD and PDD funding significantly increased the odds that a dentist would practice in a rural area (respectively, OR = 2.70; 95% CI = 1.31-5.79/OR = 2.84; 95% CI = 1.40-5.77). HRSA oral health training program funding had a positive effect on dentists choosing to practice in a rural area. By increasing the number of dentists practicing in rural communities, HRSA is improving access to, and the delivery of, oral health care services to underserved and vulnerable rural populations.

Impact of the Health Resources and Services Administration’s state oral health workforce grant program on dental workforce density and access to oral health care

BackgroundThe Health Resources and Services Administration’s Grants to States to Support Oral Health Workforce Activities, otherwise known as the State Oral Health Workforce Program (SOHWP), help states develop and implement innovations that address the workforce needs of dental Health Professional Shortage Areas in a manner appropriate to the states’ individual needs. AimThis cross-sectional study explores the broad impact of the SOHWP by comparing measures of dental workforce density and access to oral health care in states with multiple years of funding versus states with few or no years of funding. MethodsWe used data for 2006–2016 SOHWP awardees together with data from the 2016–2017 Area Health Resources Files and the 2016 Behavioral Risk Factor Surveillance System to compare numbers of dentists per 100,000 population and age-adjusted prevalence of annual dental visits among adults for long-term SOHWP-funded states versus states with few or no years of funding. ResultsMulti-year SOHWP funding is associated with higher workforce density and greater access to oral health care, especially in the Midwest and West. ConclusionAllowing states funding utilization flexibility may result in improved outcomes. This finding can help inform planning and policy about whether and how to scale future training and workforce programs to achieve greater impact.

Determinants of emergency department utilization for non-traumatic dental conditions in Massachusetts.

To study the determinants of emergency department (ED) utilization for non-traumatic dental conditions (NTDCs) by adults in Massachusetts. We analyzed patient-level factors associated with ED utilization for NTDCs in Massachusetts during 2013, using the Massachusetts All Payer Claims Dataset. The primary independent variables of interest were use of preventive dental service in the year preceding the ED visit and dental insurance coverage. Key covariates included age, gender, income, day of the ED visit, payer type, and residing in a geographically designated dental health professional shortage area (DHPSA). A multilevel logistic regression model was used to estimate the odds of NTDC ED visits as compared to two other categories of ED visits. 1.1 percent of all ED visits in Massachusetts were for NTDCs in 2013. Preventive dental service use in the preceding year decreased the odds (OR = 0.72) of a NTDC ED visit, whereas having dental insurance coverage increased the odds (OR = 1.1) of a NTDC ED visit. Other patient-level characteristics that significantly increased odds of a NTDC ED visit included being between 26 and 35 years of age (OR = 1.2), male (OR = 1.3), uninsured (OR = 1.7) or enrolled in Medicaid (OR = 1.2), and visiting on a weekend (OR = 1.3). Increased access to preventive dental services may lower likelihood of ED use for NTDCs. Interventions that target younger adults, Medicaid enrollees, and the uninsured, may be the most efficient way to lower NTDC ED use.

Estimating Demand for and Supply of Pediatric Preventive Dental Care for Children and Identifying Dental Care Shortage Areas, Georgia, 2015.

Demand for dental care is expected to outpace supply through 2025. The objectives of this study were to determine the extent of pediatric dental care shortages in Georgia and to develop a general method for estimation that can be applied to other states. We estimated supply and demand for pediatric preventive dental care for the 159 counties in Georgia in 2015. We compared pediatric preventive dental care shortage areas (where demand exceeded twice the supply) designated by our methods with dental health professional shortage areas designated by the Health Resources & Services Administration. We estimated caries risk from a multivariate analysis of National Health and Nutrition Examination Survey data and national census data. We estimated county-level demand based on the time needed to perform preventive dental care services and the proportion of time that dentists spend on pediatric preventive dental care services from the Medical Expenditure Panel Survey. Pediatric preventive dental care supply exceeded demand in Georgia in 75 counties: the average annual county-level pediatric preventive dental care demand was 16 866 hours, and the supply was 32 969 hours. We identified 41 counties as pediatric dental care shortage areas, 14 of which had not been designated by the Health Resources & Services Administration. Age- and service-specific information on dental care shortage areas could result in more efficient provider staffing and geographic targeting.

Geographic access to dental care varies in Missouri and Wisconsin.

To examine geographic access to dental providers for the general population and children with public insurance in Missouri and Wisconsin. Using a newly constructed dentist office database from the American Dental Association master file and other sources, we use the two-step floating area catchment area method to calculate population to provider ratios at the census block group level. These ratios are used to determine potential geographic dentist shortage areas. We utilize street network data to estimate travel times and catchment areas between population centers and dental offices. This methodology accounts for the actual spatial distribution of dental providers and potential dental patients. Within and across Missouri and Wisconsin, there is some variation in geographic access to dental offices for the general population and publicly insured children. More than 90 percent of publicly insured children have access to dental providers within 30 minutes. Among the states examined, Missouri has more geographic disparities to dental care. The Health Resources and Services Administration, which designates dental health professional shortage areas, relies on administrative boundaries to calculate population to dental provider ratios. These boundaries may not reflect actual or "real-time" dental care markets. The methods employed in this paper may give policymakers a template to better determine geographic dentist shortage areas.

Differences in utilization of dental procedures by children enrolled in Wisconsin Medicaid and Delta Dental insurance plans.

Few studies have directly compared dental procedures provided in public and private insurance plans for enrollees living in dental health professional shortage areas (DHPSAs). We examined the rates for the different types of dental procedures received by 0-18-year-old children living in DHPSAs and non-DHPSAs who were enrolled in Medicaid and those enrolled under Delta Dental of Wisconsin (DDW) for years 2002 to 2008. Medicaid and DDW dental claims data for 2002 to 2008 was analyzed. Enrollees were divided into DDW-DHPSA and non-DHPSA and Medicaid-DHPSA and non-DHPSA groups. Descriptive and multivariable analyses using over-dispersed Poisson regression were performed to examine the effect of living in DHPSAs and insurance type in relation to the number of procedures received. Approximately 49 and 65 percent of children living in non-DHPSAs that were enrolled in Medicaid and DDW received at least one preventive dental procedure annually, respectively. Children in DDW non-DHPSA group had 1.79 times as many preventive, 0.27 times fewer complex restorative and 0.51 times fewer endodontic procedures respectively, compared to those in Medicaid non-DHPSA group. Children enrolled in DDW-DHPSA group had 1.53 times as many preventive and 0.25 times fewer complex restorative procedures, compared to children in Medicaid-DHPSA group. DDW enrollees had significantly higher utilization rates for preventive procedures than children in Medicaid. There were significant differences across Medicaid and DDW between non-DHPSA and DHPSA for most dental procedures received by enrollees.

Travel distances by Wisconsin Medicaid enrollees who visit emergency departments for dental care.

Prior studies document increased numbers of nontraumatic dental condition (NTDC) visits to U.S. emergency departments (EDs). However, the influence of travel distance on ED use for NTDCs, particularly for Medicaid enrollees has hitherto received little attention. The authors examined the effect of travel distance on Wisconsin Medicaid enrollees' NTDC visits to EDs after adjustment for covariates. NTDC-related visits claims data for Wisconsin Medicaid (2001-2009) was analyzed. For each enrollee, travel distance to the nearest of 130 EDs in Wisconsin was determined. The number of NTDC visits per person-year was aggregated by ZIP+4 of residence. Negative binomial regression adjusting for the expected number of visits based on race, sex, age of the residents and calendar year was used to evaluate the effect of travel distance, urbanicity, and dentist-population ratio on rate of visits. Enrollees residing in rural counties, entire dental health professional shortage areas, areas with dentist population ratios >20,000: 1 and non-Hispanic Whites travelled the furthest, compared to nearest mean ED distance of 2.9 miles. Enrollees residing 3 miles away or further had significantly lower rates of NTDC visits to EDs. This study demonstrates that distance is a barrier to making NTDC-related visits to EDs. Rates of NTDC visits decreased as travel distance to the nearest ED increased for Medicaid enrollees.

County-level determinants of dental utilization for Medicaid-enrolled children with chronic conditions: How does place affect use?

Little is known about how place affects childrens’ access to dental care. We analyzed data for 25,908 Iowa Medicaid-enrolled children with chronic conditions to identify the county-level determinants of dental utilization. Our analyses suggest that higher levels of poverty and designation as a dental health professional shortage area at the county-level are associated with lower probability of child-level dental use. There are significant interactions between child-level race/ethnicity and county-level poverty as well as between child-level disability and county-level unemployment. We present a new descriptive model on dental utilization that emphasizes county-level factors as well as interactions between county-level and child-level factors.

Exploring the potential for foreign-trained dentists to address workforce shortages and improve access to dental care for vulnerable populations in the United States: a case study from Washington State

BackgroundTo address dental workforce shortages in underserved areas in the United States, some States have enacted legislation to make it easier for foreign dental school graduates to become licensed dentists. However, the extent to which foreign dental school graduates will solve the problem of dental workforce shortages is poorly understood. Furthermore, the potential impact that foreign-trained dentists have on improving access to dental care for vulnerable patients living in dental Health Professional Shortage Areas (HPSAs) and those enrolled in public insurance programs, such as Medicaid, is unknown. The objective of this paper is to provide a preliminary understanding of the practice behaviors of foreign-trained dentists. The authors used Washington State as a case study to identify the potential impact foreign dental school graduates have on improving access to dental care for vulnerable populations. The following hypotheses were tested: a) among all newly licensed dentists, foreign-trained dentists are more likely to participate in the Medicaid program than U.S.-trained dentists; and b) among newly licensed dentists who participated in the Medicaid program, foreign-trained dentists are more likely to practice in dental HPSAs than U.S.-trained dentists.MethodsThe authors used dental license and Medicaid license data to compare the proportions of newly licensed, foreign- and U.S.-trained dentists who participated in the Medicaid program and the proportions that practiced in a dental HPSA.ResultsUsing bivariate analyses, the authors found that a significantly lower proportion of foreign-trained dentists participated in the Medicaid program than U.S.-trained dentists (12.9% and 22.8%, respectively; P = 0.011). Among newly licensed dentists who participated in the Medicaid program, there was no significant difference in the proportions of foreign- and U.S.-trained dentists who practiced in a dental HPSA (P = 0.683).ConclusionsLegislation that makes it easier for foreign-trained dentists to obtain licensure is unlikely to address dental workforce shortages or improve access to dental care for vulnerable populations in the United States. Licensing foreign dental school graduates in the United States also has ethical implications for the dental workforces in other countries.
