ObjectivesTo assess the relation between Medicaid reimbursement rates and access to dental care services in the context of dentist density and dentist participation in Medicaid in each state.MethodsData were from Early and Periodic Screening, Diagnostic, and Treatment reports for 2014, Medicaid reimbursement rate in 2013, dentist density in 2014, and dentist participation in Medicaid in 2014. We assessed patterns of mediation or moderation.ResultsReimbursement rates and access to dental care were directly related at the state level, but no evidence indicated that higher reimbursement rates resulted in overuse of dental services for those who had access. The relation between reimbursement rates and access to care was moderated by dentist density and dentist participation in Medicaid. We estimate that more than 1.8 million additional children would have had access to dental care if reimbursement rates were higher in states with low rates.ConclusionsChildren who access the dental care system receive care, but reimbursement may significantly affect access. States with low dentist density and low dentist participation in Medicaid may be able to improve access to dental services significantly by increasing reimbursement rates.
