摘　　要：目的观察复合树脂嵌体修复儿童第一恒磨牙牙体缺损的临床效果。方法对儿童第一恒磨牙牙体缺损分别采用复合树脂嵌体技术和复合树脂直接充填术,复合树脂嵌体技术组75颗,复合树脂直接充填组78颗,1年后复诊检查,评价标准采用改良USPHS评价标准。结果复合树脂嵌体技术组的临床成功率在固位情况、边缘密合度、继发龋、牙龈指数指标上高于复合树脂直接充填修复组,并且存在显著差异(P<0.05)。在色泽协调性和磨耗程度指标上,临床成功率虽高于复合树脂直接充填修复组,但统计学上无显著差异(P>0.05)。结论复合树脂嵌体修复术组临床效果优于复合树脂直接充填术。Objective To investigate the clinical effects of composite resin inlays on the restoration of the children’s first permanent molars.Methods Children between 8 and 11 years old who had dental caries in the first permanent molars were enrolled.About 153 molars were randomly assigned to two groups,75 molars in group A and 78 molars in group B.The molars in group A were restored with composite resin inlays.The molars in group B was restored with composite resin directly.All these cases were followed up one year after restoration.The long term effects were evaluated by modified USPHS-criteria.Results The clinical success rates of composite resin inlays in group A in retention,marginal adaptation,the secondary caries and gingival indexes were higher than those of composite resin in group B.Also there were significant differences between two groups（P0.05）.Conclusions The clinical effects of composite resin inlays in group A were better than those of composite resin in group B.
