Abstract
INTRODUCTION: Variation in dentists' provision of types of dental services based on patients' insurance may impact population access to comprehensive care. The aim of this study was to describe differences in the types of services provided to adult patients with Medicaid versus private insurance among private practice general dentists. METHODS: The data source was a 2019 survey of private practice dentists in Iowa, and the study sample included general dentists with current or recent participation in Iowa's Medicaid program for adults (n = 264). Bivariate analyses were used to compare differences in the types of services provided to privately insured and publicly insured patients. RESULTS: Dentists reported the greatest differences in services provided to patients with public versus private insurance for prosthodontic procedures, including complete dentures, removable partial dentures, and crown and bridge services. Endodontic services were the least frequently provided category of services provided by dentists for both patient groups. Patterns were generally similar among both urban and rural providers. CONCLUSION: Access to dental care for Medicaid members should be evaluated not only on the proportion of dentists who see new Medicaid patients but also on the types of services dentists provide to this population.
