This study compared the extent to which having an intellectual or developmental disability (IDD) is associated with the rates at which newly Iowa Medicaid-enrolled children ages 3–8 had a first dental recall visit. We used survival analytic techniques to test our hypothesis that children with an IDD would have later first dental recall visits than children without an IDD. Our results suggest no significant difference in the time to first dental recall for children by IDD status (p=.99). After adjusting for covariates, the only factor associated with earlier first dental recalls was the length of time from enrollment in Medicaid to the first comprehensive dental visit. Children for whom it took >13 months to see a dentist for their first comprehensive dental visit were 1.68 times as likely to have an earlier first dental recall as children who had their first comprehensive dental visit within 4 months of enrolling in Medicaid (p<.0001). We found that having an IDD was not associated with later first dental recall visits for newly Medicaid-enrolled children ages 3–8 in Iowa. Future work should identify other factors associated with poor oral health for Medicaid-enrolled children with an IDD.
