Treatment outcomes and costs of dental sealants among children enrolled in Medicaid

Objectives. This retrospective cohort analysis of children enrolled in the North Carolina Medicaid program compared the likelihood of restorative treatments and associated cumulative Medicaid expenditures for teeth with or without dental sealants, Methods. We assessed the dental experience of the cohort of 15438 children from 1985 to 1992 on the basis of enrollment and claims files. We conducted regression analyses for outcomes (cariesrelated services involving the occlusal surface [CRSOs] of permanent first molars) and cumulative expenditures, controlling for characteristics of the child, the treating dentist, and the child's county of residence. Results. Overall, 23% of children received at least 1 sealant and 33% at least 1 CRSO. Sealants were effective in preventing CRSOs, although the degree of effectiveness was highest for children with the greater levels of CRSOs before sealant placement. Estimated cumulative Medicaid expenditures indicated expenditure savings from sealants within 2 years of application for children with 2 or more prior CRSOs. Conclusions. Sealant placement was associated with expenditure savings to Medicaid for certain highrisk children, so Medicaid and, more broadly, society will benefit by providing for sealant placement in these children.
