Sociodemographic Changes and Oral Health Inequities: Dental Workforce Considerations.

By midcentury, the US population will be remarkably more racially and ethnically diverse, with a dramatic increase in the proportion of older adults. This report addresses ongoing oral health disparities and inequitable access to care related to these changes, with emphasis on implications for the workforce, taking note of effects of the COVID-19 pandemic. Considering that social determinants shape health behaviors, reflection on the most effective type of dental workforce should take into account population characteristics and the relationship of oral health with overall health and general well-being. The dental workforce composition will need to mirror changing demographics, and effective dental health teams will be characterized by cultural competence, humility, readiness, and capacity to adapt to changes. In addition, the influence of social histories and the pandemic on health and dental care utilization is important. Equally important are the inclusion of oral health literacy in treatment planning and disease prevention, as well as oral health-related quality of life in considering outcomes of care. Providing patient-centered care for a diverse population requires tailored treatment modalities, as well as intra- and interprofessional approaches. In this way, the whole person can be cared for, including those with special health care needs, whether related to chronic disease, mental health conditions, or behavioral, physical, and social differences. Changing demographics will affect the delivery of oral health care, including who can best provide care and how, what the needs are, and in what ways prevention and treatment can most effectively be accomplished. The education of dentists must address unmet population needs, including for those with special health care concerns and older adults. These population groups are influenced by a variety of social determinants, and provision of services may need to occur in alternative care delivery settings. Identifying and addressing the needs of every patient within this broad array of new requirements will challenge dental professionals to redefine what it means to be a health care practitioner. This article describes how sociodemographic changes in the United States will challenge the dental workforce in new ways and points to research and practice needs to address these challenges. Oral health disparities and the changing oral health care needs of patients from diverse and underserved groups are discussed, with a focus on the implications for delivery of care and policies that are needed to improve oral health outcomes for all.

Oral Care Knowledge, Attitudes, and Practices of Black/African American Caregivers of Autistic Children and Non-Autistic Children.

Oral health is a vital component of overall health. Children from underserved, minoritized populations (i.e., Black/African Americans, autistic children) are at even greater risk for experiencing oral health disparities. This study aims to illuminate the oral health knowledge, attitudes, and practices of Black/African American caregivers of autistic and non-autistic children. Black/African American caregivers of children (4-to-14 years) on the autism spectrum (n = 65) or not on the autism spectrum (n = 60), participated in a survey, with input from literature reviews, interviews, previous research, and reviews by experts. Caregivers demonstrated basic knowledge of oral health with significantly lower scores for caregivers of autistic children. Caregivers care about oral health and would like to increase their knowledge. Significant differences in oral care practices were found between the autistic and non-autistic groups. Caregivers reported they can access dental services with relative ease, including finding their child a dentist, scheduling a dental appointment, and accessing transportation (personal or public) to attend the visit. Black/African American caregivers of autistic children and children without autism seem to have foundational knowledge about oral health and basic practices; however, they are interested in learning more. Therefore, tailored oral health education programs may help mitigate oral health disparities for Black/African American families.

Oral health inequities: Recommended public policies to achieve health equity.

In the United States (US), racial and ethnic minority populations experience poorer oral health than the general population. Social and commercial determinants of health embedded in structural and institutional racism and/or discrimination generate and exacerbate oral health inequities. We provide examples of oral health disparities (including oral health status and workforce issues) among selected racial and ethnic minority groups in the US. In addition, we compiled four priority areas based on research over the last two decades to guide actions to improve oral health equity. These four priority areas aim to improve health care models, interventions, and policies to help close gaps and reduce disparities in oral health and access to dental care.

Variation in General Dentists' Patterns of Sealant Use in Children with Elevated Caries Risk.

Strong evidence supports use of dental sealants to prevent tooth decay, and professional guidelines recommend use in children with elevated caries risk. However, not all children indicated for sealants receive this preventive intervention, even when they use routine dental care. The aim of this study was to explore the extent to which dentists' use of sealants varied in pediatric patients with elevated caries risk. Claims and enrollment data from a private dental program were used to identify a cohort of 6- to 17-y-olds with elevated caries risk (N = 27,677) and general dentists (N = 818) who provided services to the children. Children were identified as having elevated caries risk based on history of restorative treatment over a 5-y period (2010-2014). The 2 outcomes of interest were whether a dentist provided any sealants to children with elevated risk and, if so, the extent to which these were used during a 2-y observation period (2013-2014). A 2-stage hurdle model was used for multivariable analysis to identify dentist characteristics associated with sealant use. Over the observation period, 13.3% (n = 109) of dentists did not provide any sealants to their elevated risk patients from the study cohort. Logistic regression found that female dentists were significantly more likely to have used sealants (odds ratio = 2.27); dentist age and practice in an isolated small rural town were negatively associated with any sealant use. However, among dentists who did place sealants (n = 709), female dentists, older dentists, dentists in solo practice, and those working full-time were significantly more likely to provide sealants to a child. Overall, substantial variation in practitioners' use of sealants was observed. This is the first study to explore provider-level variation in sealant use, representing a critical step in future efforts to increase routine use of sealants by dentists and eliminate oral health disparities. Findings from this study can be used to design targeted policy and behavioral interventions to increase sealant use by general dentists. This study provides foundational evidence for future research that explores motivation and barriers to routine use of preventive dental interventions by clinicians.

Are We Getting Any Better? A Critical Analysis of Selected Healthy People 2020 Oral Health Indicators in 1999-2004 and 2013-2016, USA.

Oral health disparities are prevalent in the American population and are influenced by various social determinants. This study aimed to analyze oral health disparities in the US between 1999–2004 and 2013–2016 according to sociodemographic characteristics. This analytic cross-sectional study analyzed five oral health indicators from Healthy People 2020. A binomial test was used to compare proportions between baseline and follow-up. Only the indicator for non-treated cavities among children reached its goal. White children had the greatest decrease (−15.4%; p = 0.0428) in dental caries. Higher income determined better outcomes for adolescents (−27.54%; p = 0.00032 dental caries) and adults (−15.96%; p = 0.0143 tooth extractions). However, adults 35–44 years with the highest income had a significant increase (40.74%, p = 0.0258) in decayed teeth. This study provides evidence to suggest that some progress has been made towards reducing oral health disparities in the US, primarily among children. However, trends for certain indicators remain disparate between different racial/ethnic and income groups. Applications for the findings of this study should address the intersectional nature of social determinants of health and should center on improving the equity of services offered by public oral healthcare.

Oral Health Service Access in Racial/Ethnic Minority Neighborhoods: A Geospatial Analysis in Washington, DC, USA.

Previous studies on individual-level variables have improved our knowledge base of oral health service use. However, environmental or contextual variables are also important in understanding oral health disparities in racial and ethnic neighborhoods. Based on Bronfenbrenner’s ecological framework, this study examines the geographic availability of oral health providers in Washing-ton DC, U.S.A. Census tract-level data were drawn from the American Community Survey, joined with tract-level shapefiles, and overlaid with the geographic location of dental services throughout the city. Visual maps, descriptive statistics, and spatial lag regression models showed that census tracts with higher concentrations of African Americans were significantly farther from their nearest oral health providers (r = 0.19, p < 0.001), after controlling for neighborhood poverty rate, median age, and gender. Such findings confirm that in urban areas with highly di-verse populations such as Washington DC, racial disparities in oral health care access are signifi-cant. The study highlights that identifying neighborhoods with limited oral health care providers should be a priority in diminishing racial disparities in oral health service access. Improving access to racial/ethnic minority communities, especially African American neighborhoods, will require changes in health policies and programs, workforce development, resource allocation, community outreach, and educational programs.

Immigrant Status and Oral Health Disparities among Asian Americans in the United States

OBJECTIVES: To explore the roles of household language, foreign-born status, and citizenship on disparities in dental care, and oral health status among Asians in the U.S.&#x0D; METHODS: Based on the National Health and Nutrition Examination Survey (NHANES) 2011-2018, the author applied weighted nested logistic regression to describe the effects of household language, foreign-born status, and citizenship on dentist visits and self-rated oral health. Weighted negative binomial regression was used to explore the effects of immigrant status on the number of missing teeth. Socioeconomic status and demographic characteristics were controlled for. &#x0D; RESULTS: Asians who do not speak English at home present 1.428 times higher likelihood of irregular dentist visits, and 1.487 times higher self-rated fair/poor oral health. Respondents with no citizenship are more likely (OR=1.752) to present irregular dentist visits. Foreign-born Asians present more missing teeth (OR=1.361) than their U.S.-born counterparts.&#x0D; CONCLUSIONS: Despite the fact that Asians are often regarded as “model minorities” and/or “successful immigrants”, those with lower immigrant statuses illustrated higher risk for irregular dentist visits and disadvantaged oral health status.

The Progress of the New South Wales Aboriginal Oral Health Plan 2014–2020: A Scoping Review

There are major disparities in oral health between Aboriginal and Torres Strait Islander and non-Aboriginal and Torres Strait Islander people. The New South Wales (NSW) Aboriginal Oral Health Plan 2014–2020 was developed to improve the oral health of Aboriginal people. This scoping review describes programs that have been undertaken to implement the NSW Aboriginal Oral Health Plan 2014–2020. The methodology by Arksey and O’Malley was used to guide this review. Academic and grey literature were searched using a structured Medline, Lowitja and advanced Google searches. Articles were included if they aligned with the strategic directions of the Plan. Key information, including the aims of the study, methodology and results were recorded in a template on Microsoft Excel software. A total of 31 articles were included in this review. This included 25 articles from the academic literature and six initiatives from the grey literature. Included articles were categorised according to the six strategic directions in the NSW Aboriginal Oral Health Plan. Four studies were related to the first strategic direction, six related to strategic direction two, four related to strategic direction three, six initiatives related to strategic direction four, five related to strategic direction five, and eight related to strategic direction six. While there has been significant progress in achieving the strategic directions of the NSW Aboriginal Oral Health Plan, there is scope for continued collaboration between oral health service providers, universities and Aboriginal communities to improve oral health outcomes for Aboriginal people in NSW.

Dental Service and Resource Needs during COVID-19 among Underserved Populations.

Introduction:In response to the coronavirus disease 2019 (COVID-19) outbreak, dental services in British Columbia, Canada, were restricted to urgent and emergency cases between March 16 and May 18, 2020. It is unclear how the curtailment of oral health services has affected underserved populations who already often have limited access to dental care due to cost, fear, stigma, and discrimination.Objectives:To explore the experiences of underserved populations and their community organizations when accessing oral health services and information in British Columbia and identify their coping mechanisms employed during the curtailment of oral health care services.Methods:Semistructured, remote interviews were conducted with 13 staff and 18 members from 6 community-based organizations. These organizations serve men and women with a history of incarceration and/or experiencing poverty and homelessness, persons living with human immunodeficiency virus/AIDS, adults living with mental illness, and older adults in long-term care facilities. The interviews were audio-recorded, transcribed verbatim, and coded for emerging themes using NVivo 12 software. Thematic analysis was performed.Results:The pandemic raised concerns and hesitancy among underserved populations and further reduced access to care. In turn, those with unmet dental needs resorted to coping mechanisms, including turning to community support or medical services, self-management of dental issues, and not dealing with dental issues altogether. Community organizers and members outlined needed resources such as assistance navigating the dental care system, having a contact for dental-related questions, and member preparation for dental service changes, while emphasizing the importance of positive relationships with dental providers.Conclusion:Underserved populations who already face barriers to oral health care services experienced increased difficulty in addressing their oral health needs and concerns during the beginning of the COVID-19 pandemic. Strategies aimed at reaching out to this population and those who support them are needed to help mitigate negative coping strategies and increased oral health disparities.Knowledge Transfer Statement:This study depicts ways of addressing unmet oral health–related issues during the COVID-19 pandemic for underserved populations and their community organizations with policy implications as well as practical strategies.

Impact of Parents' Oral Health Literacy on Their Own and Their Children's Oral Health in Chinese Population.

BackgroundOral health literacy (OHL) has been recognized as a component of oral health disparities; however, the precise relationship between literacy and oral health outcomes has not been established. To explore the role of parents' OHL for their own subjective oral health, related behavior, and for the proxy assessment of their child's oral health, oral health-related behavior.MethodsSurvey data were collected from 406 parents of 4- to 7-year-old children in Beijing, China. The background characteristics, oral health assessment, oral health-related behavior, knowledge and attitudes, and diet-related questions of parents and their children were surveyed by a questionnaire. OHL was assessed with the Hong Kong Rapid Estimate of Adult Literacy in Dentistry (HKREAL-30) Scale and a revised version that asked the respondents to indicate if they understood the words (HKREALD-30-Understand).ResultsThe HKREALD-30 responses correlated with the HKREALD-30-Understand responses. The higher the parents' HKREALD-30-Understand scores, the better they described the health of their own teeth and gums, the greater their child's diet was influenced by the protein, sugar and calories of the food, and the more positive their oral health-related attitudes were. The higher the parent's HKREALD-30 scores, the healthier they described their child's teeth and gums.ConclusionsBoth the HKREALD-30 and HKREALD-30-Understand Scores correlate with parents' self and proxy oral health-related responses. Chinese parents could understand that the word would add predictive value to the prediction of how parents' oral health literacy affects their own oral health care, children's oral health and other related aspects.

Emergency Room Visits with a Non-Traumatic Dental-Related Diagnosis in Hawaii, 2016-2020.

The purpose of this study was to characterize the frequencies and patterns of emergency room (ER) visits with a non-traumatic dental-related diagnosis among adults (≥21 years old) in Hawaii, United States. This descriptive cross-sectional study used state-level inpatient and outpatient data recorded in Hawaii from 2016 to 2020. We identified dental-related ER visits using the diagnosis codes for non-traumatic dental-related conditions and summarized the frequency, rates, and cumulative total charges of the ER visits. The results show that approximately 30 thousand ER visits between 2016 and 2020 had a dental-related diagnosis. Sixty-seven percent of them had it as a principal diagnosis, amounting to USD 38.7 million total charges over the five years. A high proportion of these visits was found among those aged 21–44 years old (62%), Medicaid beneficiaries (49%), and Native Hawaiians/Part Native Hawaiians (26%). Compared to the proportions of ER visits with a secondary diagnosis, these groups had a higher proportion of ER visits with a principal diagnosis (ps < 0.001). A higher visit rate was found for those aged 21–44 years old and from less-populated counties. These results suggest that oral health disparities in age, socioeconomic status, and race/ethnicity exist in Hawaii. Our findings could provide insight in developing a framework to reduce oral health disparities, particularly among Medicaid beneficiaries and Native Hawaiians. Dental coverage with effective education in multiple dimensions is necessary to reduce non-traumatic dental-related ER visits.

Perceived racial discrimination partially mediates racial-ethnic disparities in dental utilization and oral health.

ObjectivesPerceived racial discrimination has been associated with poor health outcomes, yet its impact on oral health disparities is not understood. We examine the role of perceived racial discrimination in healthcare settings in explaining racial‐ethnic disparities in dental visits and tooth loss.MethodsWe used behavioral risk factor surveillance system (BRFSS) data for 2014 from four diverse states (AZ, MN, MS and NM) that included “reactions to race” module. Using Poisson regression to estimate risk ratios, we employed inverse odds ratio(IOR)‐weighted estimation for mediation analyses to estimate the role of perceived discrimination, after equalizing other confounders and risk factors.ResultsWe found that among those with similar risk factors, those who experienced racial discrimination were 15% less likely to visit a dentist, and 12% more likely to have tooth loss than those who were treated same as other races. Both Hispanics and non‐Hispanic Blacks were 26% less likely to visit a dentist (for Hispanics, RR = 0.74, 95%CI: 0.69–0.78; for non‐Hispanic Blacks, RR = 0.74, 95%CI: 0.70–0.79), and non‐Hispanic Blacks were 36% more likely to have tooth loss relative to non‐Hispanic Whites with similar risk factors (RR = 1.36, 95%CI: 1.28–1.45). Perceived discrimination appears to contribute to racial‐ethnic disparities in dental utilization among Hispanics, and disparities in tooth loss among non‐Hispanic Blacks, relative to non‐Hispanic Whites.ConclusionsPerceived racial discrimination partially explains the racial‐ethnic disparities in dental utilization and tooth loss among those who otherwise share the same risk factors for these outcomes. Addressing discrimination and systemic racism can reduce the racial‐ethnic disparities in oral health.

Addressing social determinants of oral health, structural racism and discrimination and intersectionality among immigrant and non-English speaking Hispanics in the United States.

BackgroundThe Hispanic population is the largest (18.5%) and fastest growing non‐majority ethnic group in the United States (US), about half of whom are non‐US born, and bears one of the highest oral disease burdens. Most current knowledge around oral health disparities in Hispanic populations examine the individual factors of culture, acculturation, and socioeconomic status. However, the root causes of this inequity; oral health literacy (OHL), social determinants of health (SDOH), structural racism and discrimination (SRD) and the intersectionality among the three, have not been well‐studied. Addressing this critical gap will be central to advancing health equity and reducing oral health‐related disparities in the Hispanic population, especially among immigrant and non‐English speaking Hispanics.ResultsRecommendations for future OHL/SDOH/SRD‐related research in oral health targeting Hispanic populations should include: (1) examining the direct and indirect effects of OHL/SDOH/SRD‐related factors and intersectionality, (2) assessing the impact of SRD on oral health using zip‐code level measures, (3) examining the role of OHL and SDOH as potential effect modifiers on the relationship between SRD and oral health outcomes, (4) conducting secondary data analysis to identify demographic, social and structural‐level variables and correlations between and among variables to predict oral health outcomes, and (5) obtaining a deeper understanding of how OHL/SDOH and SRD factors are experienced among Hispanic immigrant and migrant populations.ConclusionIt is hoped these recommendations will lead to a better understanding of the mechanisms through which OHL, SDOH and SRD impact oral health outcomes among the largest minority population in the US so they can be addressed.

Community based participatory research approaches to combat oral health inequities among American Indian and Alaska Native populations.

American Indian and Alaska Native (AI/AN) communities have experienced a history of systemic racism and still face significant oral health disparities. These disparities extend to the youngest community members in the form of early childhood caries (ECC). Although behavior and biology contribute to ECC, the conditions where people live, grow, and work, and the systems and political and economic forces that shape individual health outcomes, are thought to greatly impact ECC among AI/AN populations. To address ECC in AI/AN communities, we used a community based participatory approach that incorporated social determinants of health. We found that implementing culturally‐tailored, culturally‐centered, and AI/AN‐created materials for ECC interventions is viewed favorably by community members and tribal leaders. Because of the complexity of ECC in AI/AN communities we adopted a bundled approach of best practices to reduce ECC including: (1) incorporating locally, contextually, and culturally relevant strategies to present recommended ECC prevention approaches; (2) employing AI/AN community members as educators; (3) utilizing motivational interviewing with expectant mothers; and (4) providing fluoride varnish. Our work underscores the importance of developing trusting partnerships with each other and with our communities, drawing upon the insights of community advisory board members, and eliciting formative assessment data from tribal members to gain a more holistic understanding of our participants' lived experience to design relevant intervention materials. Incorporating local knowledge and situating Western oral health prevention approaches within culturally aligned frameworks can enhance partnerships and create sustainable materials for community work.

Microbiology-Based Instruction during Prenatal Dental Visits Improves Perinatal Oral Health Literacy.

To improve oral hygiene education, we evaluated the perception and potential impact of microbiology-focused oral hygiene instructions (OHI) given to pregnant patients. Dental hygienists provided this supplemental education and administered Saliva-Check Mutans (SCM) tests to pregnant patients (n = 188) in Obstetrics and Gynecology (OB/GYN) settings. Patients reported their self-perceived understanding of the relationship between oral bacteria and dental disease and returned postdelivery to receive a second SCM test and follow-up questionnaire (n = 47). Prior to the hygienist instruction, 84% of participants understood that bacteria caused tooth decay, while only 36% understood they could transfer these bacteria to their children. After instruction, patient understanding increased to 97% and 95%, respectively. Participants attributed these increases to the hygienist’s explanation and SCM test. In postdelivery participants, >80% reported adherence to routine oral hygiene practices, and a significant decrease in patients with high-risk levels of salivary Streptococcus mutans was determined by SCM test (p = 0.0253). Participants agreed that the SCM test (89%) and microbiology explanation (95%) should be provided to every pregnant patient. Evaluation of patient perception of this intervention highlights how focused instruction on the infectious nature of dental disease can increase perinatal oral health literacy. Microbiology-focused education should be given to pregnant patients to reduce oral health disparities.

Association Between Mental Health and Oral Health Status and Care Utilization.

Studies have shown that mental health and oral health may be correlated, with associations demonstrated between mental health problems and tooth loss, periodontal disease, and tooth decay. The COVID-19 pandemic had alarming implications for individuals' and communities' mental and emotional health. This study examined the associations between mental health status, oral health status, and oral healthcare utilization and highlighted the impact of COVID-19 on mental health. Additionally, this study examines specific sociodemographic factors that may amplify oral health disparities. A nationally representative survey was conducted to capture attitudes, experiences, and behaviors related to oral health, mental health, and unmet oral health needs. Eighteen percent of respondents were categorized as having poor mental health. Visiting the dentist in the last year was more common amongst individuals with good mental health. From the logistic regression model, mental health status, age group, race/ethnicity, education, and last dental visit were all significantly associated with of oral health status. Mental health status, age group, and income groups were all significantly associated with unmet oral health need. Future work should focus on the mental-oral health association, including determining ways to improve oral healthcare utilization and oral health status among people with poorer mental health.

Training and educational programs that support geriatric dental care in rural settings: A scoping review.

Access to dental care for older adults is challenging, especially for those living in rural areas. People living in rural areas are less likely to visit the dentist, have greater oral health needs, and face significant oral health disparities. Given the projected increase in the older adult population, the aim of this study was to conduct a scoping review (SR) to identify the current landscape of geriatric dental training in rural healthcare settings. Four guiding concepts (i.e., dental workforce, education/training, rural setting, and older adult population) were searched in PubMed, Embase (Elsevier), Dental and Oral Sciences Source (EBSCO), and ERIC (EBSCO) following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. EndNote and Covidence were used for de-duplication algorithms and title/abstract screening. Seventy-nine citations were identified for the final full-text review based on inclusion and exclusion criteria, and ten articles were eligible for data extraction as applicable to the research question. Three themes emerged from the review: geriatric dentistry inclusion within dental school curricula, clinical training at rural/remote locations, and improving geriatric oral health knowledge through interprofessional training. This SR highlights the limited number of currently trained geriatric dentists, as well as, the paucity of dental programs/curricula offered to produce competent dental geriatricians with an advanced skill set for practicing in rural settings. Our review indicates the need to expand the dental workforce, curricula, and training to better position dentists to serve the older and underserved population in rural and remote areas.

“I feel like the worst mother in the world”: Neoliberal subjectivity in Indigenous Australian oral health

Neoliberalism gained popularity during the post-Cold War period as a set of dominating ideologies, practices and policies that underpinned the movement towards globalisation. Neoliberalism champions competitive private markets, deregulation that facilitates economic activity, personal responsibility, and reduced public expenditure on infrastructure. A decade after the initial rise of neoliberalism, health inequities became concerns on the global stage. Oral health inequities aptly reflect social injustices due to the unique relation between material circumstances, access to health services and structural inequities. In Australia, Indigenous children experience early childhood caries at alarmingly higher rates than non-Indigenous children. Recently, neoliberalism has been suggested as an overwhelming contributor to Indigenous oral health disparities. This qualitative research is an extension of a single-blind parallel-arm randomised control trial that aimed to identify factors related to the increased occurrence of dental caries in Indigenous children. The objective of this constructivist grounded theory study was to generate an understanding of how neoliberal subjectivity exists for Indigenous peoples in the context of oral health in Australia. Experiences of ownership, guilt, failure, embarrassment, shame, and judgment were key in participants’ experiences of neoliberal subjectivity; these feelings were exacerbated by experiences of bullying, financial limitations, and institutional racism. We argue that individual responsibility for health, as a tenet of neoliberal ideologies, furthers Indigenous oral health inequities and that neoliberalism as a societal discourse perpetuates colonial values by benefitting the privileged and further oppressing the disadvantaged.

Oral Health, Health Service Utilization, and Age at Arrival to the U.S. among Safety Net Patients.

Background: Immigrants’ oral health disparities have not been adequately investigated using a lifecourse approach, which investigates the cumulative effects of risk and protective exposures among other considerations. Methods: We examined self-reported oral health outcomes and health care appointment outcomes among a sample of patients enrolled at a federally qualified health center in Richmond Virginia (N = 327) who were categorized into three groups by approximate age at arrival to the U.S. Results: Study participants who arrived to the U.S. prior to age 18 had better retention of natural dentition, better oral health related quality of life, and a lower proportion of dental appointments to address pain than those who arrived after age 18 or were born in the U.S. Conclusions: Im/migrants’ differentiated oral health outcomes by age at arrival to the U.S. suggest the relevance of lifecourse factors, for example the cumulative effects of risk and protective exposures, and confirm the merits of lifecourse studies of im/migrants’ oral health.
