The survival rates of restorations in primary molars were calculated after a retrospective examination of patients' dental records from a study population of 1,065 children. A random sample of 128 records showing information for 604 dental restorations was examined, coded, and analyzed by the life table method of survival analysis. The order of the survival rate of restorations from higher to lower success was preformed crowns, amalgam, composite resin, and glass ionomer restorations. A highly statistically significant difference (P = 0.0001) was found among the survival success rates of different material restorations. For preformed crowns and amalgam restorations, the median survival time was more than 5 years. The 5-year survival estimate for preformed crowns was 68% and for amalgam restorations was 60%. For composite resin the median survival time was 32 months and the 4-year survival estimate was 40%. For glass ionomer restorations, the median survival time was 12 months and the 4-year survival estimate was 5%.
在对1065名儿童的研究人群的患者牙科记录进行回顾性检查后，计算了乳磨牙修复体的存活率。随机抽取了128份记录，这些记录显示了604个牙齿修复体的信息，并通过生存分析的寿命表法进行编码和分析。修复体存活率从高到低的顺序为预成冠、银汞合金、复合树脂和玻璃离子修复体。不同材料修复体的生存成功率之间存在高度统计学显著差异（P = 0.0001）。对于预成冠和银汞合金修复体，中位生存时间超过5年。预成冠的5年生存估计率为68%，银汞合金修复体为60%。复合树脂的中位生存时间为32个月，4年生存估计率为40%。对于玻璃离子修复体，中位生存时间为12个月，4年生存估计率为5%。
