Abstract

Abstract: Transforming Children's Oral Health: The Impact of Oral Healthcare Policies on Virginia Medicaid Dental Health Outcomes.

Objectives: This dissertation uses Department of Medical Assistance Services (DMAS) administrative files at the individual and provider level from fiscal years (FY) 2011 to 2021 to systematically study the effect of recently implemented oral health policies (EBD guidelines on sealants, CMS updated quality measures, expansion of Medicaid oral healthcare for qualifying pregnant women) on oral health outcomes of Virginia Medicaid-enrolled children.

Methods: The studies employ a difference in differences regression methods (negative binomial, Poisson, and logistic) to examine the effects of oral health care policies at the institution, state, and federal level on oral health outcomes of children enrolled in the Virginia Medicaid Dental Program.

Results: The results indicate that the policies had a significant positive effect in sealant delivery rates among providers in rural areas, a significant increase in first permanent sealant receipt among Medicaid-enrolled children with an elevated risk of caries, and a significant increase in preventive services among children enrolled in the Virginia Medicaid Dental Program with mothers that received oral health care via the expansion of Medicaid for qualifying pregnant women.

Conclusion: The policies were effective in improving the oral health of children enrolled in the Virginia Medicaid Program. However, the success varied among participants of differing racial and ethnic groups and those living in urban and rural areas.
