Pediatric and general dentists' participation in the North Carolina Medicaid program: trends from 1986 to 1992.

The purpose of this study was to report trends in dentists' participation in the North Carolina Medicaid program. Medicaid claims files for dental users younger than age 21 were analyzed for seven fiscal years (FY) from 1986 to 1992. Over the study period, the number of pediatric dentists filing any Medicaid claims remained constant but the number of participating general dentists decreased slightly. Intensity of participation, as measured by mean annual reimbursement and mean number of children treated per dentist, increased from FY 89 to 92 for both provider groups. The mean value of services provided for each dental users also increased slightly during the same period. The data revealed over time pediatric dentists treated a larger proportion of the youngest Medicaid dental users.
