摘　　要：目的:探讨年轻恒磨牙牙体深缺损不同修复方式的临床效果差异。方法:选择患者357例,共480颗牙,随机分成嵌体修复,夹层充填,树脂充填,银汞充填4组,追踪观察1～2年临床疗效。结果:1年后复诊四种修复方式在牙体完整性、磨耗情况、邻接关系无显著性差异;龈缘密合度、继发龋存在组间显著性差异。2年后复诊四种修复方式牙体完整性、磨耗情况无显著性差异,在龈缘密合度,继发龋,邻接关系上存在组间显著性差异。充填1年内出现应激性疼痛,存在组间显著性差异。结论:夹层充填在预防应激性疼痛、保存健康牙髓优于其他三组,适应于年轻恒磨牙深缺损的治疗。Objective： To evaluate the efficacy of different types of restorations methods in young permanent teeth. Methods ： The analysed sample comprised 480 permanent teeth of 357 patients. Four methods were used, they were inlay restoration, interlayer retention, resin filling or amalgam filling. The patients were followed for 1-2 years. Results： There was no difference among four types nf restorations concerning structural integrity nf teeth, teeth attrition and adjacent teeth, there were significant difference among four groups concerning fitness nf crowns and recurrent caries after 1 year follow-up. There was no difference among four types of restorations concerning structural integrity of teeth, teeth attrition, there were significant difference among four groups concerning fitness of erowns,reeurrent caries and adjacent teeth after 2 years follow-up.
