Implications for the Dental Care of Vulnerable Populations if Medicaid Is Cut Back

Immunorecognition of Streptococcus mutans secreted proteins protects against caries by limiting tooth adhesion

INTRODUCTION

Childhood caries, a prevalent chronic disease, affects 60-90 % of children in industrialized regions, leading to lesions in both primary and permanent teeth. This condition precipitates hospital admissions, emergency room visits, elevated treatment costs, and missed school days, thereby impeding the child's academic engagement and increasing the likelihood of caries into adulthood. Despite multiple identified risk factors, significant interpersonal variability remains unexplained. The immune system generates a unique antibody repertoire, essential for maintaining a balanced and healthy oral microbiome. Streptococcus mutans is a primary contributor to the development of caries.

METHODS

Employing mass spectrometry, we investigated the S. mutans proteins targeted by antibodies in children both with and without caries, delineating a fundamental suite of proteins discernible by the immune systems of a majority of individuals. Notably, this suite was enriched with proteins pivotal for bacterial adhesion. To ascertain the physiological implications of these discoveries, we evaluated the efficacy of saliva in thwarting S. mutans adherence to dental surfaces.

RESULTS

Antibodies in most children recognized a core set of ten S. mutans proteins, with additional proteins identified in some individuals. There was no significant difference in the proteins identified by children with or without caries, but there was variation in antibody binding intensity to some proteins. Functionally, saliva from caries-free individuals, but not children with caries, was found to hinder the binding of S. mutans to teeth. These findings delineate the S. mutans proteome targeted by the immune system and suggest that the inhibition of bacterial adherence to teeth is a primary mechanism employed by the immune system to maintain oral balance and prevent caries formation.

CONCLUSIONS

These findings enhance our knowledge of the immune system's function in oral health maintenance and caries prevention, shedding light on how immunoglobulins interact with S. mutans proteins.

CLINICAL SIGNIFICANCE

Targeting S. mutans proteins implicated in bacterial adhesion could be a promising strategy for preventing childhood caries.

Beneficiaries' perspectives on improved oral health and its mediators after Medicaid expansion in Michigan: a mixed methods study

OBJECTIVE

To investigate self-reported improved oral health and its mediators, and job-related outcomes, of Medicaid expansion beneficiaries in Michigan.

METHODS

This cross-sectional mixed-methods study of adult "Healthy Michigan Plan" (HMP) Medicaid expansion beneficiaries included qualitative interviews with a convenience sample of 67 beneficiaries enrolled for ≥6 months, a stratified random sample survey of 4,090 beneficiaries enrolled for ≥12 months; and Medicaid claims data. We examined unadjusted associations between demographic variables and awareness of dental coverage, self-reported dental care access, dental visits, and self-reported oral health; and between improved oral health and job seeking and job performance. Multivariate analysis examined factors associated with self-reported oral health improvement, adjusting for sociodemographic characteristics, prior health insurance, and having at least one dental visit claim.

RESULTS

Among surveyed beneficiaries, 60 percent received ≥1 dental visit and 40 percent reported improved oral health. Adjusted odds ratios (aOR) for improved oral health were higher for African-American beneficiaries [aOR = 1.61; confidence interval (CI) = 1.28-2.03] and those previously uninsured for ≥12 months (aOR = 1.96; CI = 1.58-2.43). Beneficiaries reporting improved oral health were more likely to report improved job seeking (59.9 percent vs 51 percent; P = 0.04) and job performance (76.1 percent vs 65.0 percent; P < 0.001) due to HMP. Interviewees described previously unmet oral health needs, and treatments that improved oral health, functioning, appearance, confidence, and employability.

CONCLUSION

Michigan's Medicaid expansion contributed to self-reported improved oral health, which was associated with improved job outcomes. Policymakers should consider the importance of Medicaid dental coverage in reducing oral health disparities and improving the health and socioeconomic well-being of low-income adults and communities when considering this optional benefit.

Entrustable Professional Activities in Oral Health for Primary Care Providers Based on a Scoping Review

Despite advances in oral health care, inequalities in oral health outcomes persist due to problems in access. With proper training, primary care providers can mitigate this inequality by providing oral health education, screening, and referral to advanced dental treatment. Diverging sets of oral health competencies and guidelines have been released or endorsed by multiple primary care disciplines. The aim of this study was to transform multiple sets of competencies into Entrustable Professional Activities (EPAs) for oral health integration into primary care training. A scoping review of the literature between January 2000 and December 2016 was conducted according to PRISMA methodology to identify all existing sets of competencies. The following primary care disciplines were included in the search: allopathic/osteopathic medical schools and residency programs in family medicine, internal medicine, and pediatrics; physician assistant programs; and nurse practitioner programs. Competencies were compared using the Health Resources and Services Administration Integration of Oral Health and Primary Care Practice competencies as the foundational set and translated into EPAs. The resulting EPAs were tested with a reactor panel. The scoping review produced 1,466 references, of which 114 were selected for full text review. Fourteen competencies were identified as being central to the integration of oral health into primary care. These were converted to seven EPAs for oral health integration into primary care and were mapped onto Accreditation Council for Graduate Medical Education residency competency domains as well to the Association of American Medical Colleges EPAs for graduating medical students. The resulting EPAs delineate the essential, observable work required of primary care providers to ensure that oral health is treated as a critical determinant of overall health.

Academic and Community Partnerships: Increasing Access Through Collaborative Care

Access to quality dental care for many adults and children remains a serious concern. Many communities throughout the U.S. are at great disadvantage for preventive care and treatment due to payment concerns, location and types of providers, and poor communication between dental providers and primary care professionals. Voids in shared technology and information also persist. Integrating primary care with oral health can boost both preventive care and interventions focused on increasing efficacy and efficiency between dental and primary care professionals in addressing the onset and duration of disease. Academic and community partnerships can help increase access to care and bring together the dental and medical communities for better integration and care coordination. Academic and community partnerships promote the sharing of information, facilitate provision of basic diagnostic services, and bring the bidirectional flow of knowledge, training, and skills to one another in a systematic and sustained manner.
