Oral Health Disparities Across the Life Span

Exploring masticatory performance: a bibliometric analysis of studies published in the Web of Science database from 1950 to 2024

Objectively evaluating an individual's capacity for food fragmentation (masticatory performance) is crucial for understanding oral physiology and dental rehabilitation processes. Our aim was to conduct a bibliometric analysis of the literature focusing on masticatory performance. We conducted a survey in Web of Science up to August 31, 2024, applying specific category filters. Two calibrated reviewers manually tabulated the data, extracting information on title, authorship, keywords, institutions, countries, number of citations, year of publication, journal title, study design, masticatory test, population, and dentition status. VosViewer software generated collaborative network maps, while JAMOVI was used to perform ANOVA and Poisson regression analyses. The selection process resulted in 814 articles published between 1950 and 2024, with a recent increase to at least 50 articles per year. The average impact factor was 3.16, with around 30 citations per article. Citations were significantly influenced by the masticatory performance technique, publication year, and journal impact factor. The comminution test was the most prevalent (n = 411). Most studies focused on adults (n = 420) and older adults (n = 361), in which natural dentition (n = 404) and complete dentures (n = 214) were the most widely assessed parameters. The most frequent study designs were cross-sectional (n=489) and prospective (n = 145). The leading countries were Japan (n=202), Brazil (n=134), and the Netherlands (n = 69), and the Journal of Oral Rehabilitation was the most recurrent journal (n = 162). This study highlights the growing interest in evaluating masticatory performance, with a significant increase in publications over the years. This study highlights the need for further research involving children and longitudinal study designs, as well as studies evaluating rehabilitations with removable partial denture and implant-supported prostheses.

Partnering with periodontal patients and care providers to establish research priorities for patient engagement in specialized periodontal care: A study protocol

INTRODUCTION

Periodontitis is highly prevalent and disproportionately affects vulnerable populations, including older adults, racial and ethnic minorities, and low-income individuals. While periodontal therapies are largely effective, patient engagement in periodontal care is problematic. The study describes in this protocol aims to identify the top ten research priorities or uncertainties for specialized periodontal care (SPC) that are most important to periodontal patients and care providers.

METHODS

The James Lind Alliance approach will guide the priority-setting partnership (PSP), which involves several steps: forming a PSP steering committee, gathering potential research uncertainties, summarizing the research uncertainties, verifying unanswered uncertainties, completing an interim priority setting survey, and facilitating a priority setting workshop. Study participants will be periodontal patients (n ~ 150) and care providers (n ~ 120), including general dentists, periodontists, and dental hygienists in Alberta, Canada. A steering committee representing the four stakeholder groups will oversee the study. Data on uncertainties from these groups will be gathered through two online surveys and focus groups. Demographic data (e.g., age, sex) will be collected to describe participants and ensure representation of all stakeholder groups. Uncertainties submitted by participants will be evaluated against the existing evidence gathered through a scoping review to determine if they have already been addressed. Unanswered uncertainties will be taken to a workshop where participants (n ~ 20) representing all the stakeholder groups will set the top ten research priorities. Data analysis will include descriptive statistics and content analysis. The study is expected to conclude in August 2026.

CONCLUSION

Study findings will be disseminated to raise awareness among researchers and funders on research priorities that matter most to patients and dental care providers regarding patient engagement in SPC.

Pacific oral health: a scoping review

Introduction

A growing body of literature reports on the oral health of Pacific peoples but a synthesis of the existing knowledge on Pacific oral health epidemiology is absent. This scoping review aims to summarise the evidence on Pacific oral health epidemiology. The findings of this review may help identify knowledge gaps and issues requiring health policy prioritisation.

Methods

The review followed the PRISMA-ScR guidelines for scoping reviews and included reports published prior to July 2023 on Pacific oral health, regardless of design. Searches were conducted across four databases, and the grey literature.

Results

An analysis of 95 sources, primarily from 2000 to 2023 and predominantly New Zealand-based, found that a high proportion of Pacific peoples (including children) were affected by poor oral health and challenges in accessing dental care services. Numerous studies have reported oral health disparities, with poorer oral health among Pacific peoples than other population groups. Epidemiological and health services data from Pacific Island nations show a high prevalence of dental conditions, along with limited healthcare resources and workforce shortages. Studies on the broader social determinants shaping these issues and health promotion strategies to address them were limited.

Conclusion

This review revealed significant unmet oral health needs, ethnic disparities in oral health, and barriers preventing care in Pacific populations. The findings emphasise the need for more research to address these gaps to help develop effective, culturally-informed oral health strategies for Pacific communities.

Oral Health Differences Between Middle-Aged and Older Adults in South Korea

INTRODUCTION AND AIMS

The oral health characteristics of middle-aged and older adults exhibit variations. This study identifies the various factors associated with oral health among middle-aged and older adults through a subgroup analysis by age group of data representative of the South Korean population.

METHODS

We examined influencing factors: demographic, socioeconomic, dental, physical attributes, psychological, and mental attributes. Oral health was assessed using the Geriatric Oral Health Assessment Index. The participants were divided into two groups: those under 65 years of age (middle-aged) and those over 65 years of age (older adults). We used multiple linear regression analysis and dominance analysis to determine the dominant factors associated with oral health.

RESULTS

A total of 6369 participants were aged 69.2 ± 9.8 years on average, and 57.5% were women. Dominance analysis revealed that lower educational levels and activity difficulty caused by diseases were significantly associated with both groups. Moreover, depressive symptoms were the foremost adverse factor linked to oral health in the middle-aged (P < .001, standardized beta [β] = -4.30, general dominance index [GDI] = 19.00) and older (P < .001, β = -0.30, GDI = 10.70) adults. The number of teeth exhibited the most positive association with oral health in both middle-aged (P < .001, β = 0.20, GDI = 5.30) and older (P < .001, β = 0.23, GDI = 7.40) adults. However, cognitive function, dental visits, body mass index, severe pain, functional limitations, and cognitive function exhibited distinct patterns between the age groups.

CONCLUSION

Depressive symptoms and the number of teeth significantly influence oral health in middle-aged and older adults, though the impact varies by age. These findings stress the importance of tailored strategies considering age-specific attributes for effective oral health improvement.

CLINICAL RELEVANCE

Enhancing oral health requires healthcare providers to prioritize monitoring age-specific risk factors. Further, educational plans should highlight the importance of preventive oral care and regular dental visits.

Combined Phase 1/2a Initial Clinical Safety Trials and Proof-of-Concept Assessment of a Novel Antimicrobial Peptide KSL-W Anti-Plaque Chewing Gum

OBJECTIVES

The effective control of dental plaque is crucial for oral health, given that pathogenic bacteria in plaque are the primary cause of dental caries. Current antimicrobial agents, although effective, disrupt the oral microbiome and lead to oral dysbiosis, hindering efforts to curb dental caries. Novel antimicrobial peptides offer a promising solution due to their selective bactericidal activity against cariogenic bacteria. This study explores the initial safety and efficacy of KSL-W formulated into chewing gum through a Phase 1 and 2a clinical trial.

METHODS

The combined trial, approved by the FDA, follows a double-blind, randomized, placebo-controlled design. Phase 1 assessed safety with single doses (2-100 mg), whereas Phase 2a explored both safety and proof of concept in reducing oral bacteria with multiple doses (4-75 mg). Besides adverse events (Phase 1), outcome measures included whole-mouth plaque and gingival index scores and bleeding on probing (Phase 2a).

RESULTS

KSL-W demonstrated safety in both phases, with no severe adverse events. The proof-of-concept analysis revealed a decrease in plaque and gingival inflammation, particularly at doses ≥ 20 mg. The 30 mg dose appeared to yield optimal effects without any adverse reactions in subjects.

CONCLUSIONS

Results from this study indicate that KSL-W is safe for use in humans and provides initial evidence of its potential efficacy in reducing plaque and gingival inflammation. Further research is essential to determine optimal usage and ultimate safety, and to assess its potential in diverse populations.

TRIAL REGISTRATION

The trial is registered with the FDA (Trial Registration Number: NCT01877421). The clinical trials were registered in the clinicaltrials.gov database under the title "Safety and Tolerability of Antiplaque Chewing Gum in a Gingivitis Population" and the identifier number is NCT01877421. The URL for accessing the study in clinicaltrials.gov is https://clinicaltrials.gov/study/NCT01877421?intr=Antiplaque%20chewing&rank=1.

Socioeconomic vulnerability and access to community water fluoridation in Washington

BACKGROUND

The aim of the authors was to determine whether socioeconomic vulnerability is associated with community water fluoridation (CWF).

METHODS

The authors used US Census Bureau data to create 4 county-level vulnerability markers (percentages non-White, Hispanic or Latino, below the federal poverty threshold, education below high school), obtained county-level CWF data from the Washington State Department of Health, and evaluated associations using Spearman rank correlation coefficient and the Kruskal-Wallis rank sum test. The authors then interviewed 122 community members in Washington (December 2022-March 2023) and analyzed the interview data inductively.

RESULTS

A higher percentage of non-White people at the county level was associated with a significantly higher level of CWF (Spearman rank correlation coefficient, 0.55; 95% CI, 0.29 to 0.82; P < .001), whereas county-level poverty was associated with significantly lower CWF (Spearman rank correlation coefficient, -0.36; 95% CI, -0.70 to -0.03; P = .02). High school completion was not associated with county-level CWF. Significantly larger proportions of Hispanics and Latinos lived in counties with higher CWF (P < .05). From the interviews, more participants thought tap water was healthy than unhealthy, but 41% had mixed feelings. Similarly, more participants thought CWF was acceptable than unacceptable, with 35% reporting mixed feelings. Negative views about tap water and CWF were more common among non-White participants.

CONCLUSIONS

People in racially and ethnically diverse communities in Washington appear to have greater access to CWF, whereas those in lower-income communities have poorer access.

PRACTICAL IMPLICATIONS

CWF is an important population-level strategy to prevent caries. Additional work is needed to improve access to CWF, especially for people from low-income communities.

Access to dental services in an elder population of African descent in Brazil

OBJECTIVES

We investigated access to dental services and associated factors in a community of Quilombola older people.

BACKGROUND

Quilombola populations are groups of individuals descended from black Africans subjected to slavery during part of Brazilian history. As marginalised and neglected individuals, they have high rates of negative indicators and require further attention to the social determinants that affect their health reality.

MATERIALS AND METHODS

A cross-sectional quantitative study was conducted in the Quilombola community of Castainho, in the Northeast region of Brazil. In this community, 34 older people aged between 65 and 74 resided. We collected self-report data on sociodemographic and economic characteristics, along with oral examinations by the researchers. The primary dependent variable was regular access to dental services. Statistical analysis used Fisher's exact test (P = .05).

RESULTS

Among the 32 participants in the final sample, 18.8% (n = 6) reported accessing dental services in the previous 6 months. Self-declared individuals of mixed race, with positive self-assessment of oral health, and those who did not self-perceive the need for treatment had lower rates of regular access to dental services (P < .05).

CONCLUSION

Use of dental services by older Quilombola people is low, and there are differences by ethnicity and individual perception of oral health.

Late-Stage Oral Cancer Detection After California and Illinois Restored Medicaid Dental Benefits

Objective

Previous research found an association between California's Medicaid dental coverage and oral cancer detection. However, this relationship has yet to be explored in other states or by subgroup populations.

Study Design

In addition to controlling for sociodemographic and tumor characteristics, this study implemented a traditional difference-in-differences design to compare distant-stage diagnosis trends in states restoring Medicaid dental benefits (California [CA] and Illinois [IL]) with trends in states with constant Medicaid dental benefits.

Setting

This retrospective, observational study analyzed oral cavity and pharynx cancer case data from The Surveillance, Epidemiology, and End Results program (2004-2017).

Methods

The outcome was a binary variable indicating whether a patient was diagnosed at a distant stage. Subgroup analyses were conducted by state, race/ethnic group, sex, age, and county-level household income.

Results

The sample included 109,997 adults diagnosed with cancer of the oral cavity and pharynx. Restoring Medicaid dental benefits was associated with a statistically significant 2.7%-point decline in the probability of a distant-stage oral cancer diagnosis. This estimate represented a 14% relative change from baseline rates. Results were consistent for CA and IL and by county-level median income. Estimates were significantly larger for adults under age 65, males, and adults identifying as Hispanic; non-Hispanic Black; American Indian; or Asian American or Pacific Islander.

Conclusion

Restoring Medicaid dental coverage improved early detection in both CA and IL, with the greatest reductions in distant-stage diagnoses occurring in younger adults, males, and minoritized racial/ethnic groups. Future research should investigate whether earlier detection reduces oral cancer mortality disparities.

The Global Prevalence and Severity of Dental Caries among Racially Minoritized Children: A Systematic Review and Meta-Analysis

Racially minoritized children often bear a greater burden of dental caries, but the overall magnitude of racial gaps in oral health and their underlying factors are unknown. A systematic review and meta-analysis were conducted to fill these knowledge gaps. We compared racially minoritized (E) children aged 5-11 years (P) with same-age privileged groups (C) to determine the magnitude and correlates of racial inequities in dental caries (O) in observational studies (S). Using the PICOS selection criteria, a targeted search was performed from inception to December 1, 2021, in nine major electronic databases and an online web search for additional grey literature. The primary outcome measures were caries severity, as assessed by mean decayed, missing, and filled teeth (dmft) among children and untreated dental caries prevalence (d > 0%). The meta-analysis used the random-effects model to calculate standardized mean differences (SMD) and 95% confidence intervals (95% CI). Subgroup analysis, tests for heterogeneity (I2, Galbraith plot), leave-one-out sensitivity analysis, cumulative analysis, and publication bias (Egger's test and funnel plots) tests were carried out. The New Castle Ottawa scale was used to assess risk of bias. This review was registered with PROSPERO, CRD42021282771. A total of 75 publications were included in the descriptive analysis. The SMD of dmft score was higher by 2.30 (95% CI: 0.45, 4.15), and the prevalence of untreated dental caries was 23% (95% CI: 16, 31) higher among racially minoritized children, compared to privileged groups. Cumulative analysis showed worsening caries outcomes for racially marginalized children over time and larger inequities in dmft among high-income countries. Our study highlights the high caries burden among minoritized children globally by estimating overall trends and comparing against factors including time, country, and world income. The large magnitude of these inequities, combined with empirical evidence on the oral health impacts of racism and other forms of oppression, reinforce that oral health equity can only be achieved with social and political changes at a global level.

A Systematic Review and Meta-Analysis on Oral Health Disparities Among the Indigenous Paediatric Population

There is a knowledge gap in the literature regarding oral health disparities (OHD) in minority and indigenous (IG) paediatric cohorts that needs to be addressed. Disparities in oral health among children are a pressing concern, highlighting inequities in access to dental care and meeting needs. The current systematic review aims to provide a comprehensive synthesis of the prevailing understanding of OHD in the minority and IG strata. A meticulous search strategy was formulated by a team of reviewers to identify pertinent studies from databases of PubMed, MEDLINE, Scopus, Google Scholar and EMBASE. Data extraction and article selection strictly adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The Newcastle-Ottawa Scale (NOS) was employed to evaluate the methodological quality of the studies included. Review Manager version 5.4 was used to synthesise quantitative data. A total of five cross-sectional studies were included in the final analysis. The findings consistently demonstrated the existence of racial and socioeconomic disparities in oral health across varying age groups and geographical locations in the defined population. Significant disparities in oral health outcomes were observed between IG and non-IG populations, with IG and minority groups exhibiting a heightened vulnerability to oral health challenges. Through a meta-analysis of the compiled data, a statistically significant association was established between children (being a member of a minority group) and unmet oral health needs. Socioeconomic status (SES) and maternal education were factors that showed a significant impact on oral health disparity. All studies were graded to be of the low-risk category based on the NOS risk of bias tool. This review successfully identified several influential factors contributing to oral health disparities, such as cultural practices, dietary patterns and access to oral healthcare services. Additionally, discernible differences in oral health status were evident between IG and non-IG children, with IG children enduring a greater burden of oral health difficulties. These findings underscore the imperative for targeted interventions and policy measures aimed at addressing the specific oral health needs of minority and IG paediatric populations, with the overarching goal of mitigating the existing disparities.

Oral Health Disparities and Inequities in Older Adults

The number of individuals 65 and older living in the United States is increasing substantially and becoming more racially and ethnically diverse. This shift will affect the demographics of the patient population seeking dental care. It will also impact the future treatment needs of older adults. In older adults, similar to the general adult population, oral health disparities continue to exist related to race, ethnicity, gender, and socioeconomic level. Dental practitioners must understand these changes in order to meet the challenges of providing oral health care to the increasing numbers of diverse, medically compromised, and cognitively impaired older adults.

Mixed methods evaluation of an oral health education program for pediatric dental, medical and nursing providers

PURPOSE

To evaluate the application of knowledge, attitudes, and skills learned in an oral health education program among pediatric dental and medical residents, and pediatric and family nurse practitioners (PNPs and FNPs).

METHODS

A mixed methods study design included a year-end online survey and focus groups. Eighty participants completed the survey (94%) and seven focus groups were conducted (n = 69) representing each of the four cohorts in 2020-2022. Analysis of variance was used to assess differences in survey responses by dental/medical specialty. Focus group audio recordings were analyzed using Atlas.ti.22 to identify common themes.

RESULTS

The program increased knowledge and skills in oral health core competencies and positive attitudes regarding oral health education. All PNPs (100%) and most pediatric medical residents (94%) and FNPs (91%) strongly agreed/agreed that the oral health program led to an increase in screening for early childhood caries, more confidence in applying fluoride varnish and providing oral health anticipatory guidance during patient visits. Most pediatric medical residents, PNPs and FNPS (98%) strongly agreed/agreed that primary care providers should incorporate oral health into their practice and provide referrals to dental professionals as part of well-child visits.

CONCLUSIONS

The program improved oral health-related knowledge, attitudes and skills among dental and medical primary care providers. Future oral health education programs for health care professionals can use this model to help bridge the gap between dental and primary care and ultimately improve access to preventive oral health care for children and families.

Caries risk and social determinants of health: A big data report

BACKGROUND

Oral health is influenced by social determinants of health (SDH), predisposing people and communities to greater risk of developing caries. This study evaluated the association between caries risk in adults and SDH such as ZIP Codes, systemic diseases, payment methods, and race or ethnicity.

METHODS

The BigMouth Dental Data Repository (n = 57,211) was used to extract clinical and SDH data from patients' dental electronic health records for 2019. Caries risk categories were used as ZIP Code data was merged with the Social Deprivation Index, a composite measure of area-level deprivation based on 7 demographic characteristics collected in the American Community Survey.

RESULTS

The results showed that the odds of being in the high caries risk group were higher for people in the 49- to 64-year age group (adjusted odds ratio [aOR], 2.24; 95% CI, 2.08 to 2.40; P ≤ .001), men (aOR, 1.19; 95% CI, 1.13 to 1.25; P ≤ .001), people who had comorbidities (diabetes: aOR, 1.16; 95% CI, 1.08 to 1.24; P ≤ .001; cardiovascular disease: aOR, 1.40; 95% CI, 1.32 to 1.50), and people with an Social Deprivation Index score above the 75th percentile (aOR, 2.39; 95% CI, 2.21 to 2.58; P ≤ .001). In addition, Hispanic and Black people had higher odds of being at high caries risk than other races or ethnicities (Hispanic: aOR, 3.05; 95% CI, 2.32 to 4.00; Black: aOR, 2.05; 95% CI, 1.02 to 4.01).

CONCLUSIONS

This study shows the association of caries risk with higher social deprivation, reinforcing the role of structural and upstream factors in oral health. This study is unique in using recorded ZIP Code information and assessing caries risk levels for those regions.

PRACTICAL IMPLICATIONS

The physical and structural environment should be considered contributors to caries risk in people.

Integrating Oral Health into Health Professions School Curricula

Oral health is essential to human health. Conditions associated with poor oral health involve all organ systems and many major disease categories including infectious disease, cardiovascular disease, chronic pain, cancer, and mental health. Outcomes are also associated with health equity. Medical education organizations including the Association of American Medical Colleges and National Academy of Medicine recommend that oral health be part of medical education. However, oral health is not traditionally included in many medical school, physician assistant, or nurse practitioner curricula. Several challenges explain this exclusion including lack of time, expertise, and prioritization; we therefore provide suggestions for integrating oral health education into the health professions school curriculum. These recommendations offer guidance for enhancing the oral health curriculum across institutions. We include key organizational and foundational steps, strategies to link oral health with existing content, and approaches to achieve curricular sustainability.

Subgingival Microbiome in Pregnancy and a Potential Relationship to Early Term Birth

Background

Periodontal disease in pregnancy is considered a risk factor for adverse birth outcomes. Periodontal disease has a microbial etiology, however, the current state of knowledge about the subgingival microbiome in pregnancy is not well understood.

Objective

To characterize the structure and diversity of the subgingival microbiome in early and late pregnancy and explore relationships between the subgingival microbiome and preterm birth among pregnant Black women.

Methods

This longitudinal descriptive study used 16S rRNA sequencing to profile the subgingival microbiome of 59 Black women and describe microbial ecology using alpha and beta diversity metrics. We also compared microbiome features across early (8-14 weeks) and late (24-30 weeks) gestation overall and according to gestational age at birth outcomes (spontaneous preterm, spontaneous early term, full term).

Results

In this sample of Black pregnant women, the top twenty bacterial taxa represented in the subgingival microbiome included a spectrum representative of various stages of biofilm progression leading to periodontal disease, including known periopathogens Porphyromonas gingivalis and Tannerella forsythia. Other organisms associated with periodontal disease reflected in the subgingival microbiome included several Prevotella spp., and Campylobacter spp. Measures of alpha or beta diversity did not distinguish the subgingival microbiome of women according to early/late gestation or full term/spontaneous preterm birth; however, alpha diversity differences in late pregnancy between women who spontaneously delivered early term and women who delivered full term were identified. Several taxa were also identified as being differentially abundant according to early/late gestation, and full term/spontaneous early term births.

Conclusions

Although the composition of the subgingival microbiome is shifted toward complexes associated with periodontal disease, the diversity of the microbiome remains stable throughout pregnancy. Several taxa were identified as being associated with spontaneous early term birth. Two, in particular, are promising targets of further investigation. Depletion of the oral commensal Lautropia mirabilis in early pregnancy and elevated levels of Prevotella melaninogenica in late pregnancy were both associated with spontaneous early term birth.

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.

Addressing Black men's oral health through community engaged research and workforce recruitment

BACKGROUND

Racism negatively affects the life experiences and subsequent health of Black men, including oral disease prevalence and outcomes. Few examples in the literature discuss how racism may affect successful, unsuccessful, and non-attempts to address Black men's oral health.

AIMS

This commentary describes anti-racism approaches to address Black men's oral health through community-based participatory research, oral health promotion, and workforce recruitment.

MATERIALS AND METHODS

Stakeholders from two organizations and one dental school share their experiences and key insights on how to strengthen efforts while minimizing the influence of racism on Black men's participation.

RESULTS

Common insights identified were a need to engage a diverse range of Black men within varying social and economic contexts, race and gender concordance among program leaders and participants, and the value of partnership to reach Black men in places where they feel comfortable and supported.

DISCUSSION AND CONCLUSION

These examples stress the imperative of addressing racism among Black men in the development and improvement of targeted oral health interventions. They also emphasize the value of commitment from institutional leadership, relationship building with Black men, and the empowerment of Black men to lead program development and implementation efforts.

Disparities in Dental Service Use among Adult Populations in the United States

OBJECTIVES

This article aims to examine the disparities in dental service utilization among 3 age groups: younger adults (20-49 y), middle-aged adults (50-64 y), and older adults (65+ y), among Whites, Hispanics, Blacks, Asians, American Indians or Alaska Natives (AIAN), and Native Hawaiian or other Pacific Islanders (NHOPI).

METHODS

Weighted logistic regression models were conducted to analyze 9 waves of cross-sectional survey data (2002-2018) from the Behavioral Risk Factor Surveillance System. We estimated age group- and race/ethnic-specific prevalences of dental service utilization adjusting sociodemographics and self-rated health for each wave and compared with crude analysis. Next, we performed linear regression analysis of the trend of adjusted prevalences over time and the average level by race/ethnicity and age groups.

RESULTS

Racial/ethnic disparities increased with age, even though the adjusted prevalences of dental service utilization were less apparent than the crude analysis. The all-wave average prevalence was 71%. Black older adults had the lowest level of dental service utilization (65%) as compared with the 2 highest groups: White older adults (79%) and Asian older adults (76%). The general younger adult populations had low prevalences, with the lowest among Asian younger adults (65%). AIAN and NHOPI individuals from all age groups tended to have average or below average prevalences. In addition, a decreasing trend of dental service utilization was observed among White individuals of all age groups (0.2%-0.3% lower per year, P < 0.01) and AIAN younger adults (0.5% lower per year, P < 0.01).

CONCLUSION

Health policy, federal funding, and community-based programs should address the needs of dental service utilization for racial/ethnic minorities including Blacks, AIANs, and NHOPIs.

KNOWLEDGE TRANSFER STATEMENT

Our study offers insights into our understanding of disparities in dental service utilization among minority racial/ethnic groups. As health policy, federal funding, and community-based programs seek to improve oral health, there is a need to address access to and utilization of dental service for Blacks, American Indians or Alaska Natives, and Native Hawaiian or other Pacific Islanders.

Emergency department use for nontraumatic dental conditions among children and adolescents: NEDS 2014-2015

OBJECTIVES

Despite great efforts to improve paediatric dental care access in the last two decades, the use of emergency departments (ED) for dental conditions among children that are more appropriately addressed in dental offices remains a public health concern in the United States. We examined factors associated with ED visits for nontraumatic dental conditions or NTDCs and ED visits for any other reason among children and adolescents.

METHODS

A retrospective secondary data analysis of ED visits was conducted using the 2014-2015 Nationwide Emergency Department Sample (NEDS) data. NTDCs were further categorized as diseases of hard tissue (eg dental caries), pulp/periapical (eg root canal infections), gingival/periodontal (eg conditions that affect the supporting tissues) and other. We included patient/socioeconomic characteristics, disposition, time of visit, and the Grouped Charlson Comorbidity Index (GRPCI) in our analysis. Bivariate associations were tested using chi-squared test (α = 0.05).

RESULTS

There were 70 616 194 ED visits in 2014-15, with 465 353 (0.7%) visits for NTDCs. Statistically significant differences were observed for all patient characteristics tested, except for gender when comparing children visiting the ED for NTDCs and children visiting for any other reason. Medicaid was the expected payer for nearly 60% of all ED visits, and the uninsured shared a larger proportion of NTDC visits (19.4%) than other visits (8.8%). Late adolescents (aged 18-21) accounted for over 50% of NTDC visits but only one-fifth of all other types of ED visits. Late adolescents (18-21 years old) who were uninsured had a significantly higher proportion of NTDC visits. Of all NTDC visits, 19.1% were related to hard tissue disease, 25.3% pulp/periapical, 7.9% periodontal disease, and the remaining were grouped as other dental diseases.

CONCLUSIONS

The ED use for NTDCs is more common among late adolescents, Medicaid and uninsured groups. Examining and implementing new approaches that improve access to routine dental care for these groups may help in reducing inefficient ED use related to NTDCs.

Oral Health Disparities and Inequities in Older Adults

The number of individuals 65 and older living in the United States is increasing substantially and becoming more racially and ethnically diverse. This shift will affect the demographics of the patient population seeking dental care. It will also impact the future treatment needs of older adults. In older adults, similar to the general adult population, oral health disparities continue to exist related to race, ethnicity, gender, and socioeconomic level. Dental practitioners must understand these changes in order to meet the challenges of providing oral health care to the increasing numbers of diverse, medically compromised, and cognitively impaired older adults.

Self-Reported Oral Health, Oral Hygiene and Associated Factors in Lithuanian Adult Population, 1994-2014

This study aimed to examine 20-year trends (1994-2014) in self-reported oral health and oral hygiene and to assess the associated factors in a Lithuanian population aged 20-64 years. Nationally representative cross-sectional data on 8612 men and 11,719 women were obtained from 11 biennial postal surveys of Lithuanian health behavior monitoring. Dentate status was assessed by asking about the number of missing teeth. Over the study period, the proportion of men with all teeth increased from 17.5% to 23.0% and the same proportion increased in women-from 12.5% to 19.6%. The prevalence of edentulousness was 2.8% in 2014. The proportion of individuals brushing teeth at least twice a day increased from 14.6% to 31.9% in men and from 33.0% to 58.8% in women. Multivariate logistic regression analysis revealed that older age, lower education, living in rural areas, daily smoking, confectionary consumption (only in women), obesity, no visits to a dentist during the past year, toothache and brushing teeth less than twice a day increased the odds of missing six or more teeth. Efforts should be made to promote good oral hygiene habits, prevent and control behavioral risk factors and increase access to dental care among risk groups.

Working collaboratively across schools to promote oral health education through interprofessional education

PURPOSE

The Association of American Medical Colleges and American Dental Education Association have identified oral health knowledge, skills, and attitudes shared by both medical and dental professionals. Although oral health was deemed an essential competency for medical practitioners, our state struggled to ensure learners received proper training. This training deficit resulted in conducting a needs assessment and implementing an oral health interprofessional module at our schools.

METHODS

First-year medical students and clinical faculty were emailed surveys in 2016 to obtain baseline information. A team of faculty and students from the Schools of Medicine and Dentistry reviewed the curriculum to determine where to augment oral health content. An oral health module to teach a basic head, neck, and oral examination to first-year medical students during their patient-centered care small-group sessions was implemented and evaluated.

RESULTS

Only 13.6% of faculty respondents were aware of national oral health competency recommendations, and <50% rated oral health important for primary care physicians (PCPs) to include in history, physical exam, or oral health counseling. On baseline, ≤25% of PCP respondents reported integrating the listed skills in their practice, and most indicated lacking expertise to teach oral health. Teaching sessions were rated helpful by students and faculty. After the teaching sessions, ratings on the importance of including oral health significantly increased from baseline.

CONCLUSION

Collaboration between Schools of Dentistry and Medicine successfully integrated oral health into medical school curriculum and improved the tutors' attitudes of its importance.

Feasibility and acceptability of an oral pathology asynchronous tele-mentoring intervention: A protocol

Introduction: Oral cancer remains prevalent, despite being largely preventable. The widespread use of technology at chairside, combined with advances in electronic health record (EHR) capabilities, present opportunities to improve oral cancer screening by dentists, especially for disadvantaged patients with severe health needs. Design and methods: Using a mixed-methods approach, we will evaluate the feasibility and acceptability of integrating a telementoring component into the identification of oral lesions using the following 3 methods: 1) administering provider surveys that consist of a checklist of 10 key components of the intervention based on process, and asking the dental provider subjects if each one was covered; 2) conducting semi-structured interviews informed by the Consolidated Framework for Implementation Research and the Implementation Outcomes Framework with dental resident subjects to assess specific barriers to sustaining the intervention and strategies for addressing these barriers to facilitate integration of the intervention into the routine workflow of the dental clinics; and 3) administering brief exit interviews with patient subjects regarding the acceptability of the intervention to assess satisfaction with the use of intra-oral cameras at chairside to screen for and refer patients with oral lesions and identification of these oral lesions via EHR and secure e-mail tele-mentoring with an oral pathology expert. Expected impact of the study for public health: If successful, then later clinical trials will maximize the external validity of the intervention and facilitate the widespread implementation and dissemination of the model for the teaching of dentists and residents, with the ultimate goal of improving patient care.

Nutritional problems in childhood and adolescence: a narrative review of identified disparities

To inform programmes and policies that promote health equity, it is essential to monitor the distribution of nutritional problems among young individuals. Common nutritional problems include overall low diet quality, the underconsumption and overconsumption of certain dietary components, unhealthy meal and snack patterns, problematic feeding practices and disordered eating. The objective of the present narrative review was to summarise recent evidence of disparities among US children (2-19 years) according to age, sex, socio-economic status, ethnicity/race and rural-urban location. Searches in PubMed® and MEDLINE® were completed to identify peer-reviewed research studies published between January 2009 and January 2019. Findings from the ninety-nine reviewed studies indicate adolescent females, young individuals from lower socio-economic households and individuals who identify as non-Hispanic Black race are particularly vulnerable populations for whom targeted strategies should be developed to address evidence of increased risk with regards to multiple aspects of nutritional wellbeing. Limitations of the existing evidence relate to the accuracy of self-reported dietary data; the need for consistent definitions of disordered eating; the focus on individual dietary components v. patterns; the complexities of categorising socio-economic status, ethnicity/race, and rural and urban areas; and the cross-sectional, observational nature of most research designs. There is an urgent need for research to address these limitations and fill a large gap in evidence on rural-urban differences in nutritional problems. It will further be important for future studies to build greater understanding of how nutritional problems cluster among population groups.

Gingivitis and plaque scores among residents of low-income senior housing

OBJECTIVES

The purpose of this paper is to present Gingival Index (GI) and Plaque Scores (PS) of older and disabled adults living in low-income senior housing and their association with sociodemographic, health status and oral health behaviours.

METHODS

Participants were recruited from six low-income senior housing residences in Connecticut. Primary outcome measures were Gingival Index (GI) and Plaque Scores (PS). Surveys assessed sociodemographic characteristic, beliefs and behaviours. Logistic regression analysis was used to model the binary outcomes of probability of unfavourable GI status (>=0.34) and unfavourable PS (>=74%) against variables including demographic characteristics, oral hygiene behaviours and health status.

RESULTS

331 participants volunteered for the study. Mean baseline GI was 0.38 (SD: 0.3), and mean PS was 71.7% (SD: 18%). Logistic regression showed that males were more likely to have higher GI and plaque scores than females. Those with less formal education were more likely to have worse GI scores and high PS compared to those with college educations. Those with lower incomes and those who rated their oral health poor/fair were more likely to have higher PS.

CONCLUSION

Participants had remarkably good gingival health regardless of relatively high PS. Males and less educated individuals should receive special attention when implementing oral hygiene interventions because of their relatively poor oral hygiene status.

A qualitative study of the multi-level influences on oral hygiene practices for young children in an Early Head Start program

BACKGROUND

Individual child-level risk factors for Early Childhood Caries (ECC) have been studied, but broader family- and community-level influences on child oral hygiene behaviors are less well understood. This study explored multiple levels of influence on oral hygiene behaviors for young children in Early Head Start (EHS) to inform a future behavioral intervention targeting children from low-income families.

METHODS

Twenty-four semi-structured interviews were conducted with mothers of children under 4 years old, enrolled in the home visitor (HV) component of one EHS program in Los Angeles, CA, who participated in the BEhavioral EConomics for Oral health iNnovation pilot study (BEECON) in 2016-7. Audio-recordings of interviews were translated if needed, and transcribed in English, and coding and analysis was facilitated by Dedoose qualitative software. This investigation used general thematic analysis guided by the Fisher-Owens child oral health conceptual framework to identify influences on oral hygiene behaviors for the young children.

RESULTS

Many mothers reported brushing their children's teeth twice/day, and concern that most children frequently resisted brushing. They identified children being sick or tired/asleep after outings as times when brushing was skipped. Several child-, family-, and community-level themes were identified as influences on child oral hygiene behaviors. At the child-level, the child's developmental stage and desire for independence was perceived as a negative influence. Family-level influences included the mother's own oral hygiene behaviors, other family role models, the mother's knowledge and attitudes about child oral health, and mothers' coping skills and strategies for overcoming challenges with brushing her child's teeth. Overall, mothers in the EHS-HV program were highly knowledgeable about ECC risk factors, including the roles of bacteria and sugar consumption, which motivated regular hygiene behavior. At the community-level, mothers discussed opportunities to connect with other EHS-HV families during parent meetings and playgroups that HV coordinated. A few mothers noted that EHS-HV playgroups included brushing children's teeth after snacking, which can be a potential positive influence on children's hygiene practices.

CONCLUSION

Child-, family- and community-level factors are important to consider to inform the development of tailored oral health preventive care programs for families in EHS-HV programs.

Are There Alternatives to Invasive Site Development for Dental Implants? Part I

Edentulous sites are often characterized by inadequate bone volume for dental implant therapy. Bone augmentation procedures for site development involve longer healing period and are often invasive, costly, and associated with postoperative morbidity. This article discusses alternatives to invasive bone grafting procedures that are often used to develop implant sites. Owing to the broad nature of this topic, it is presented in two articles. In part I, the use of short and narrow-diameter implants are discussed. Part II reviews the use of tilted as well as fewer implants to support a prosthesis.

Socioeconomic inequalities in adult oral health across different ethnic groups in England

BACKGROUND

Ethnic inequalities in oral health among British adults remain largely unexplored. This study explored the role of socioeconomic position (SEP) in explaining ethnic inequalities in oral health; and the consistency of socioeconomic inequalities in oral health across ethnic groups.

METHODS

Data from 45,599 adults, aged 16 years and over, who participated in the Health Survey for England were pooled across 5 years. The seven ethnic groups included were White British, Irish, Black Caribbean, Indian, Pakistani, Bangladeshi and Chinese. Edentulousness and toothache were the outcome measures. A composite measure of SEP was developed based on education, social class, income and economic activity using confirmatory factor analysis. Ethnic inequalities in oral health were assessed in logistic regression adjusting for sex, age, survey year and SEP.

RESULTS

Indian (OR: 0.55, 95%CI: 0.40-0.76), Pakistani (0.56, 0.38-0.83), Bangladeshi (0.35, 0.23-0.52) and Chinese (0.41, 0.25-0.66) were less likely to be edentulous than White British after controlling for SEP. Irish (1.22, 1.06-1.39) and Caribbean (1.37, 1.19-1.58) were more likely and Bangladeshi (0.83, 0.69-0.99) were less likely to have toothache than White British after controlling for SEP. Socioeconomic inequalities in edentulousness were consistently found across almost all ethnic groups while socioeconomic inequalities in toothache were found among White British and Irish only.

CONCLUSION

This study shows that the role of SEP in explaining ethnic inequalities in oral health depended on the outcome being investigated. Socioeconomic inequalities in oral health among minority ethnic groups did not consistently reflect the patterns found in White British.
