Dentists Who Participate in Medicaid: Who They Are, Where They Locate, How They Practice.

Low utilization of dental services among low-income individuals and racial minorities reflects pervasive inequities in U.S. health care. There is limited research determining common characteristics among dentists who participate in Medicaid or the Children's Health Insurance Program. Using detailed Medicaid claims data and a provider database, we estimate that among dentists with 100 or more pediatric Medicaid patients, 48% practice in high-poverty areas, 10% practice in rural areas, and 29% work in large practices (11 or more dentists). Among those with zero Medicaid patients, 18% practice in high-poverty areas, 4% practice in rural areas, and 11% work in large practices. We found that dentist race/ethnicity has an independent effect on Medicaid participation even when adjusting for community characteristics, meaning non-White dentists are more likely to treat Medicaid patients, regardless of the median income or racial/ethnic profile of the community.
