OBJECTIVE This study evaluated the association between patient medical history and the outcomes of restorative procedures performed under general anesthesia. METHODS The dental records of patients who had dental rehabilitation under general anesthesia at Children's Hospital in Boston (1990-1992) and Children's National Medical Center in Washington, DC (1994-1998) were examined. Data regarding restorative outcomes and the association between patient medical history and restorative failures were assessed using chi-square tests with correction for continuity. T-tests were performed on parametric data. RESULTS Significantly higher stainless steel crown failure rates were found in young patients diagnosed with developmental disabilities when compared to patients without such disabilities (p<0.025, x2 = 5.50). However, there was no difference in the failure rates of SSCs in young patients with significant medical histories compared to patients without significant medical histories. Regarding amalgam and composite restorations, there were no differences in failure rates among patients with and without significant medical histories, including developmental disabilities. CONCLUSIONS SSC failures were higher in young children with developmental disabilities compared to children without these disabilities.
