A closer look at disparities in earnings between white and minoritized dentists.

OBJECTIVE: To examine the factors that account for differences in dentist earnings between White and minoritized dentists. DATA SOURCES: We used data from the American Dental Association's Survey of dental practice, which includes information on 2001-2018 dentist net income, practice ZIP code, patient mix between private and public insurance, and dentist gender, age, and year of dental school graduation. We merged the data on dentist race and ethnicity and school of graduation from the American Dental Association masterfile. Based on practice ZIP code, we also merged the data on local area racial and ethnic composition from the American Community Survey. STUDY DESIGN: We used a linear Blinder-Oaxaca decomposition to assess observable characteristics that explain the gap in earnings between White and minoritized dentists. To assess differences in earnings between White and minoritized dentists at different points of the income distribution, we used a re-centered influence function and estimated an unconditional quantile Blinder-Oaxaca decomposition. DATA EXTRACTION METHODS: We extracted data for 22,086 dentists ages 25-85 who worked at least 8 weeks per year and 20 hours per week. PRINCIPAL FINDINGS: Observable characteristics accounted for 58% of the earnings gap between White and Asian dentists, 55% of the gap between White and Hispanic dentists, and 31% of the gap between White and Black dentists. The gap in earnings between White and Asian dentists narrowed at higher quantiles of the income distribution. CONCLUSIONS: Compared to other minoritized dentists, Black dentists have the largest earnings disparities relative to White dentists. While the level of the explained component of the disparity for Black dentists is comparable to the explained part of the disparities for other minoritized dentists, the excess percentage of the unexplained component for Black dentists accounts for the additional amount of disparity that Black dentists experienced. Persistent income disparities could discourage minoritized dentists from entering the profession.

Dentists Who Participate in Medicaid: Who They Are, Where They Locate, How They Practice.

Low utilization of dental services among low-income individuals and racial minorities reflects pervasive inequities in U.S. health care. There is limited research determining common characteristics among dentists who participate in Medicaid or the Children's Health Insurance Program. Using detailed Medicaid claims data and a provider database, we estimate that among dentists with 100 or more pediatric Medicaid patients, 48% practice in high-poverty areas, 10% practice in rural areas, and 29% work in large practices (11 or more dentists). Among those with zero Medicaid patients, 18% practice in high-poverty areas, 4% practice in rural areas, and 11% work in large practices. We found that dentist race/ethnicity has an independent effect on Medicaid participation even when adjusting for community characteristics, meaning non-White dentists are more likely to treat Medicaid patients, regardless of the median income or racial/ethnic profile of the community.

Practice patterns of postgraduate trained dentists in the United States.

OBJECTIVE: Postgraduate dental (PGD) primary care training has grown significantly. This study examines the individual, educational, community, and policy factors that predict practice patterns of PGD-trained dentists. STUDY DESIGN: Individual dentist records from the 2017 American Dental Association Masterfile, with indicators of Medicaid participation and practice in a Federally Qualified Health Center (FQHC), were linked to postdoctoral training, community/practice location, and state policy factors. Generalized logistic models, adjusted for these factors, were used to predict PGD-trained dentists: (1a) serving Medicaid children, (1b) accepting new Medicaid patients, and (2) working in an FQHC. RESULTS: Individual attributes that predicted serving Medicaid children included all race/gender combinations (vs. White females), and foreign-trained dentists and contractors/employees/associates (vs. practice owners). Black women are most likely to work in an FQHC. Residency attributes that predicted serving Medicaid children and working in an FQHC were Health Resources and Services Administration postdoctoral funding and being community based. Dentists practicing in rural or high-poverty communities were more likely to serve Medicaid children and work at FQHCs. States with higher levels of graduate medical education investment, higher Medicaid rates, and more generous adult dental Medicaid benefits increased the likelihood of serving Medicaid children, while states with more expansive adult dental Medicaid benefits increased the likelihood of working in an FQHC. CONCLUSION: Federal training investment in PGD education combined with Medicaid payment and coverage policies can strongly impact access to dental care for vulnerable populations. Yet, oral health equity cannot be achieved without increasing dentist workforce diversity.

Trends in postgraduate dental training in the United States.

OBJECTIVE: This study examines the individual, educational, and policy factors that predict dentists pursuing postgraduate dental (PGD) training. METHODS: Individual dentist records from the 2017 American Dental Association Masterfile were linked with pre-doctoral training attributes and state-level dental policy factors. Generalized logistic models, adjusted for individual, educational, and policy factors, were used to predict: (1) attending any PGD program, and (2) primary (i.e., advanced general practice, pediatrics, or dental public health, per the Health Resources and Services Administration [HRSA]) versus specialty care. RESULTS: The majority of new PGD residency slots (77%) were in primary care. Women held 56% of primary care slots; men held 62% of specialty slots. Individual characteristics that predicted PGD primary care training included being Black, Hispanic, Asian, or other race; being male or older age reduced the odds. Pre-doctoral school characteristics that predicted PGD primary care training included having a pre-doctoral HRSA grant, affiliation with an academic medical center, and being a historically Black college/university; being a private school or in a small metro area lowered the odds. At the policy level, the strongest predictors of attending PGD primary care training are a residency requirement in the state you currently practice in and federal graduate medical education (GME) investment per residency slot. CONCLUSION: Pursuing PGD training is variable based on the race/ethnicity/gender of the dentist. Federal investments in pre-doctoral dental education and GME can drive equity, as they significantly increase the odds that dentists will go on to PGD training, as do state licensure requirements.

US dental health care workers' mental health during the COVID-19 pandemic.

BACKGROUND: This study was designed to assess the prevalence of anxiety and depression symptoms and understand factors influencing mental health among dental health care workers (DHCWs) during the COVID-19 pandemic. METHODS: Beginning in June 2020, 8,902 DHCWs participated monthly in an anonymous longitudinal, web-based survey (response rate, 6.7%). The Patient Health Questionnaire-4 was used to estimate rates of anxiety and depression symptoms. Changes in mental health over time and differences by demographic and practice characteristics, COVID-19 community transmission level, and COVID-19 vaccination status were tested using χ2 tests and multilevel multivariable logistic regression. RESULTS: Anxiety symptom rates peaked in November 2020 (28% of dental hygienists, 17% of dentists) and declined to 12% for both professions in May 2021. Depression symptom rates were highest in December 2020 (17% of dental hygienists, 10% of dentists) and declined to 8% in May 2021. Controlling for gender, age, race or ethnicity, and COVID-19 community transmission level, the authors found that dentists had significantly lower odds of anxiety symptoms (adjusted odds ratio [aOR], 0.82; 95% CI, 0.70 to 0.95) and depression symptoms (aOR, 0.79; 95% CI, 0.67 to 0.93) than dental hygienists. Compared with vaccinated respondents, those who were unvaccinated but planning on getting vaccinated had significantly higher rates of anxiety (aOR, 1.71; 95% CI, 1.20 to 2.44) and depression (aOR, 1.57; 95% CI, 1.07 to 2.29) symptoms. CONCLUSIONS: DHCWs' mental health fluctuated during the pandemic. Anxiety and depression in DHCWs were associated with demographic and professional characteristics as well as perceived risk of COVID-19. PRACTICAL IMPLICATIONS: Mental health support should be made available for DHCWs. This clinical trial was registered at ClinicalTrials.gov. The registration numbers are NCT04423770 and NCT04542915.

United States Dental Health Care Workers' Mental Health During the COVID-19 Pandemic.

Purpose: The purpose of this study was to assess the prevalence of anxiety and depression symptoms and understand factors influencing mental health among dental health care workers (DHCWs) in the United States (US) during the COVID-19 pandemic.Methods: Beginning in June 2020, dentists (DDS) and dental hygienists (DH) in the US were invited to participate monthly in an anonymous, longitudinal, web-based survey. The Patient Health Questionaire-4 (PHQ-4) was used to estimate rates of anxiety and depression symptoms. Changes in mental health over time and differences by demographic and practice characteristics, COVID-19 community transmission level and COVID-19 vaccination status were tested using χ2 tests and multilevel multivariable logistic regression.Results: A total of 8,902 DHCWs (DH, DDS) participated in the survey for a response rate of 6.7%. Anxiety symptom rates peaked in November 2020 (28% DH; 17% DDS) and declined to 12% for both professions in May 2021. Depression symptoms were highest in December 2020 (17% DH; 10% DDS) and declined to 8% in May 2021. Controlling for gender, age, race, ethnicity and community COVID-19 transmission levels, DDS respondents had lower odds of anxiety symptoms (aOR 0.82; 95% CI 0.70 to 0.95) and depression symptoms (aOR 0.79; 95% CI 0.67 to 0.93) than DHs. Compared to vaccinated respondents, DHCWs who were unvaccinated but were planning on getting vaccinated had significantly higher rates of anxiety (aOR 1.71; 95% CI 1.20 to 2.44) and depression symptoms (aOR 1.57; CI 1.07 to 2.29).Conclusions: The mental health status of DHCWs fluctuated during the COVID-19 pandemic. Anxiety and depression were associated with the demographic and professional characteristics of the DHCW as well as the perceived risk of COVID-19 infection. Mental health support should be made available for all DHCWs.

The 2021 report on oral health in America: Directions for the future of dental public health and the oral health care system.

In the two decades between Oral Health in America: A Report of the Surgeon General and Oral Health in America: Advances and Challenges much good happened but intractable challenges persist. Inequity in oral health status, utilization, and access to care continue to negatively affect the health and economic wellbeing of Americans and their families, local, state, and federal health care systems, and American society overall. To move the nation forward, we argue that: more emphasis is needed in prevention; access to care must be improved to mitigate inequity; newer understandings of oral disease must be leveraged in the service of health and health care; the value that oral health brings to economic wellbeing must be elucidated; better policy choices must be made in all of the above; and more effective oral health care leaders in driving policy change must be trained.

COVID-19 Vaccine Intention and Hesitancy of Dental Hygienists in the United States.

Purpose: Vaccinations represent an important public health tool for mitigating dangerous diseases; nevertheless, there is concern and hesitancy regarding vaccinations including those for COVID-19. The purpose of this study was to determine the intentions and hesitancy among dental hygienists in the United States (US) toward COVID-19 vaccination.Methods: Dental hygienists in the US were surveyed from 1/4/21 to 8/16/21 regarding their intentions to get vaccinated and whether they received a COVID-19 vaccine. The vaccination questions were part of an anonymous, ongoing longitudinal web-based survey of dental hygienists' employment and infection control trends. Willingness or actual COVID-19 vaccination versus vaccine hesitancy were analyzed by differences in demographic characteristics using multivariable logistic regression and X2 and Fisher's exact tests.Results: Full COVID-19 vaccination rates in US dental hygienists rose sharply from 2/5/21 to 3/5/21 (26.0% to 53.9%) and leveled off to 75.4% by 8/30/21. The highest rates of vaccine hesitancy were among dental hygienists aged 26-39 years and those who had contracted COVID-19 during the time of the survey. The lowest vaccination hesitancy rates were seen among Non-Hispanic Asians and individuals 65+. When controlling for age, race/ethnicity, and years practiced, dental hygienists who had contracted COVID-19 had higher odds of being vaccine hesitant (adjusted Odds Ratio (aOR): 1.847, 95% Confidence Interval (CI): 1.274, 2.678). Having contracted COVID-19 was also associated with respondents changing from being hesitant to be vaccinated to being willing to be vaccinated (aOR: 4.071, 95% CI: 1.652, 10.030).Conclusion: Although vaccine acceptance is high among dental hygienists in the US, vaccine hesitancy remains an ongoing concern. Dental hygienists are key prevention specialists who should promote adherence to vaccination recommendations for the health of the public. Further education in virology, epidemiology, and vaccination education is recommended.

Employment Patterns of Dental Hygienists in the United States During the COVID-19 Pandemic: An update.

Purpose: Despite recovery in dental practices' patient volume, dentists in the United States (US) continue to report difficulties in hiring dental hygienists due to the COVID-19 pandemic. This study updates previous data on US dental hygienists' employment patterns and attitudes concerning returning to work.Methods: Licensed dental hygienists were invited to participate in monthly web-based surveys between September 2020 and August 2021. Employment questions included current and pre-pandemic work status as well as reasons for not currently working as a clinical dental hygienist. Descriptive statistics were used to describe dental hygienists' employment status and reasons for not currently working. Cross tabulation analysis included employment status and reasons for not working by age group.Results: As of August 2021, 4.9% (n=59) of the participants reported that they were not currently employed as a dental hygienist. Most reported that the reason for non-employment as a dental hygienist was voluntary (74.1%; n=43).Safety concerns for self and others were the primary reasons for not returning to work; participants also indicated retirement or that they no longer wished to practice due to the pandemic. However, the percentage of respondents citing insufficient childcare, wanting the COVID-19 vaccine but not obtaining it, and having an underlying health condition, decreased between the beginning and the conclusion of the study.Conclusion: A measurable degree of hesitancy among US dental hygienists to return to work has persisted over a year and a half into the pandemic and may continue despite some improvements in workplace safety and vaccine uptake. Future research should examine workforce levels after the pandemic resolves.

Infection Prevention and Control Practices of Dental Hygienists in the United States During the COVID-19 Pandemic: A longitudinal study.

Purpose: The SARS-CoV-2 virus continues to mutate, and the COVID-19 pandemic remains a global health crisis. The purpose of this longitudinal study was to continue to analyze the use of infection prevention and control practices (IPC) and personal protective equipment (PPE) by dental hygienists in the United States (US) during the COVID-19 pandemic.Methods: Web-based surveys on COVID-19 related health, IPC, and PPE were administered monthly to a panel of US licensed dental hygienists (n=6,976) from September 2020 to August 2021. Trends over time and predictors of IPC and PPE use were estimated using Stata 17.0 xt commands and multilevel multivariable logistic regression. Linear regression modeling for trends in time and tests for changes in trends were conducted (Joinpoint Regression Program, Version 4.9.0.0).Results: Almost all practicing dental hygienists (99.9%, 14,926 observations) reported COVID-19 specific IPC in place at their primary dental practice. Consistently >96% of dental hygienists reported operatory disinfection and staff masking over the study period. Patient face masking and physical protections such as barriers or air filtration increased in use over time, then declined in spring 2021. Screening or interviewing patients before appointments, checking patient temperatures before treatment, checking staff temperatures at shift start, disinfecting frequently touched surfaces, and encouraging distance between patients were reported by >85% of respondents until March 2021, at which point significant decreases were observed. Wearing a mask or respirator and eye protection during patient care consistently rose over time from September 2020 (77.1%) to August 2021 (81.4%). Always wearing a N95 or equivalently protective respirators during aerosol generating procedures peaked in 2/2021 and declined thereafter. Dental practice setting, supply of respirators, COVID-19 vaccination, and COVID-19 community transmission level were significantly associated with IPC and PPE use.Conclusion: Most US dental hygienists reported always wearing masks and eye protection during patient care and a variety of IPC types have been instituted to reduce the risk of COVID-19 transmission in dental practice settings. However, the use of N95 or equivalent respirators and some additional IPC methods declined during 2021.

Time for Dental Care to Be Considered Essential in US Health Care Policy.

Training, service delivery, and financing are done separately in dentistry and general health care, which has influenced reimbursement structures, access to services, and outcomes. This article considers how medical and dental separation exacerbates health inequity and canvasses data demonstrating that oral health and dental services are the least affordable health services. This article also proposes how dental and general medical care coverage can be meaningfully integrated through better health policy to motivate health equity.

Comparative analysis of dental procedure mix in public and private dental benefits programs.

BACKGROUND: There is little published research on whether public and private dental benefits plans affect the types of oral health care procedures patients receive. This study compares the dental procedure mix by age group (children, working-age adults, older adults), dental benefits type (Medicaid and Children's Health Insurance Program, private), and level of Medicaid dental benefits by state (emergency only, limited, extensive). METHODS: The authors extracted public dental benefits claims data from the 2018 Transformed Medicaid Statistical Information System. To compare procedure mix with beneficiaries who had private dental benefits, the authors used claims data from the 2018 IBM MarketScan dental database. The authors categorized dental procedures into specific service categories and calculated the share of procedures performed within each category. They analyzed procedure mix by age, plan type (fee-for-service, managed care), and adult Medicaid benefit level. RESULTS: Aside from orthodontic services, the dental procedure mix among children with public and private benefits is similar. Among adults with public benefits, surgical interventions make up a higher share of dental procedures than routine preventive services. CONCLUSIONS: Children with public benefits have a procedure mix comparable with those with private benefits. There are substantial differences in procedure mix between publicly and privately insured adults. Even in states that provide extensive dental benefits in Medicaid, those programs primarily finance invasive surgical treatment as opposed to preventive treatment. PRACTICAL IMPLICATIONS: There is a need to assess best practices in publicly funded programs for children and translate those attributes to programs for adults for more equitable benefit design and care delivery across public and private insurers.

COVID-2019 among dentists in the United States: A 6-month longitudinal report of accumulative prevalence and incidence.

BACKGROUND: In 2020, the Centers for Disease Control and Prevention and the America Dental Association released COVID-19 infection control interim guidance for US dentists, advising the use of optimal personal protection equipment during aerosol-generating procedures. The aim of this longitudinal study was to determine the cumulative prevalence and incidence rates of COVID-19 among dentists and to assess their level of engagement in specific infection control practices. METHODS: US dentists were invited to participate in a monthly web-based survey from June through November 2020. Approximately one-third of initial respondents (n = 785) participated in all 6 surveys, and they were asked about COVID-19 testing received, symptoms experienced, and infection prevention procedures followed in their primary practice. RESULTS: Over a 6-month period, the cumulative COVID-19 infection prevalence rate was 2.6%, representing 57 dentists who ever received a diagnosis of COVID-19. The incidence rates ranged from 0.2% through 1.1% each month. The proportion of dentists tested for COVID-19 increased over time, as did the rate of dentists performing aerosol-generating procedures. Enhanced infection prevention and control strategies in the dental practice were reported by nearly every participant monthly, and rates of personal protection equipment optimization, such as changing masks after each patient, dropped over time. CONCLUSIONS: US dentists continue to show a high level of adherence to enhanced infection control procedures in response to the ongoing pandemic, resulting in low rates of cumulative prevalence of COVID-19. Dentists are showing adherence to a strict protocol for enhanced infection control, which should help protect their patients, their dental team members, and themselves. PRACTICAL IMPLICATIONS: COVID-19 infections among practicing dentists will likely remain low if dentists continue to adhere to guidance.

COVID-19 Prevalence and Related Practices among Dental Hygienists in the United States.

Purpose: Throughout the COVID-19 pandemic, health care professionals have been challenged to provide appropriate preventive and therapeutic measures while using precautions to minimize disease transmission. The purpose of this study was to estimate the prevalence of COVID-19 among United States (US) dental hygienists, describe infection prevention and control procedures and any associated trends in mental health.Methods: Registered dental hygienists (RDHs) licensed in the US were invited to participate in a 30-question web-based survey. COVID-19 infection items included probable and confirmed results, COVID-19 related symptoms experienced in the last month, and level of concern about COVID-19 transmission to patients and themselves. The validated Patient Health Questionnaire 4 screened respondents for depression or anxiety. Personal protective equipment (PPE) use when treating patients was assessed. The research protocol and survey were approved by the American Dental Association IRB and registered at clinicaltrials.gov (NCT04542915). Kruskal-Wallis and X2 tests were used to test for associations between PPE use, PPE supply, mental health symptoms, and concern about COVID-19 transmission.Results: As of October 8, 2020, a total of 4,776 dental hygienists from all 50 states and Puerto Rico participated in the study. Respondents reported elevated symptoms of anxiety and depression. Of the respondents, 3.1% (n=149) had ever tested positive or been diagnosed with COVID-19. The majority of respondents (99.1%; n=3,328) who practiced dental hygiene reported their primary dental practice had enhanced infection prevention or control efforts in response to the pandemic. PPE use was significantly associated with years of experience as a dental hygienist, level of concern about COVID-19, and level of PPE supplies available (p-values<0.01), but not type of dental practice (p-value 0.1).Conclusion: As of October 2020, the estimated prevalence rate of dental hygienists in the US having had COVID-19 was low. There is a need for further support for dental hygienists' use of PPE and mental health.

Employment Patterns of Dental Hygienists in the United States During the COVID-19 Pandemic.

Purpose: The COVID-19 pandemic has led to drops in patient volume and staffing in dental practices in the United States (US). This study aimed to provide insights on dental hygienists' employment patterns as well as their attitudes toward working as dental hygienists during a pandemic.Methods: Licensed dental hygienists were invited to participate in a web-based 30-question survey between September 29 and October 8, 2020. Employment questions included current and pre-pandemic work status, reasons for not currently working as a dental hygienist, and estimated levels of personal protective equipment (PPE) in the primary work location. All statistical analysis was conducted in Qualtrics Core XM; cross tabulation was used to examine dental hygienist working patterns and attitudes by age, practice PPE supply, and other factors.Results: The COVID-19 pandemic has led to an estimated 8% reduction in dental hygienist employment. The majority (59.1%, n=205) of this reduction is voluntary, with the main reason being general concerns over COVID-19 (48.3%, n=100). Other reasons include issues surrounding childcare and concerns over safety measures in the workplace. Dental hygienists aged 65 and older were most likely to have left the workforce voluntarily. More than half of respondents reported that their work locations had more than a two-week supply of most PPE items, although about 10% did not know supply levels. Dental hygienists working in settings with lower supplies of PPE were more concerned with COVID-19 transmission risk to themselves or to patients.Conclusion: COVID-19 has led to a reduction in the dental hygienist workforce that is likely to persist until the pandemic passes.The dental hygienist labor market has tightened and employers may continue to experience difficulties in filling vacant dental hygienist positions until the pandemic subsides. There is also likely to be a longer term, yet smaller, impact on dental hygiene employment levels.
