The failure rates of restorative procedures for children undergoing dental rehabilitation under general anesthesia, performed by pediatric dental residents in advanced educational programs, were evaluated in order to determine treatment outcomes and best practices.
Retrospective review of 504 dental records of children receiving comprehensive dental treatment under general anesthesia at children's hospitals in Boston between 1990-1992 and in Washington, DC, between 1994-1998, were undertaken. Data regarding restoration outcomes were evaluated using chi square tests with correction for continuity. Only records of patients who returned for follow-up at least six months after their rehabilitations were evaluated. T-tests were performed on parametric data.
Two-hundred and forty-one (48%) of the records were evaluated. Stainless steel crowns (SSCs) had significantly lower failure rates than amalgams (P<0.001, chi2=63). The highest failure rates were seen in composites (P<0.001, chi2=112) and composite strip crowns (P<0.001, chi2=121).
SSCs are the most reliable restorations while composite restorations are the least durable. Failure of restorations appears to be related to follow-up length.
评估在全身麻醉下接受牙齿修复治疗的儿童患者中，由参加高级教育项目的儿科牙科住院医师实施的修复治疗程序的失败率，以确定治疗结果和最佳实践方法。
对1990 - 1992年在波士顿儿童医院以及1994 - 1998年在华盛顿特区儿童医院接受全身麻醉下综合牙科治疗的504名儿童的牙科记录进行回顾性研究。使用连续性校正的卡方检验评估修复结果的数据。仅评估修复后至少六个月返回进行随访的患者记录。对参数数据进行t检验。
共评估了241份（48%）记录。不锈钢冠（SSC）的失败率显著低于汞合金（P<0.001，卡方=63）。复合树脂修复体（P<0.001，卡方=112）和复合树脂带环冠（P<0.001，卡方=121）的失败率最高。
不锈钢冠是最可靠的修复体，而复合树脂修复体最不耐用。修复体的失败似乎与随访时间长短有关。
