摘　　要：目的:探讨复合树脂充填治疗后牙牙体缺损的临床疗效。方法:选择2009～2010我科收治的后牙牙体缺损临床需行充填治疗的患牙252颗,随机分成两组,实验组患牙经常规预备后,窝洞壁经酸蚀处理,使用3M复合树脂充填,可见光固化。对照组采用常规预备后,使用银汞合金充填。两组分别于充填1、2年后随访,观察充填齿继发龋、充填物松动脱落、牙纵折的发病情况。结果:1年后随访,两组充填齿继发龋、充填物松动脱落、牙纵折的发病情况对比无显著性差异(P>0.05)。2年后随访,实验组充填齿继发龋、充填物松动脱落、牙纵折的发生率明显低于对照组,组间比较有统计学差异(P<0.05)。结论:3M复合树脂充填后牙治疗后牙牙体缺损,具有银汞合金承受咬合力的优点;同时又克服了银汞合金因物理镶嵌易产生继发龋、易纵折的缺点;另外还具有操作时间充裕,材料无浪费,无汞害等优点。Objective： To discuss the clinical effects of composite resin fillings on the treatment of tooth defect.Methods：A total of 252 molars with tooth defect from 2009 to 2010 were chosen and divided into two groups randomly.After routine oral preparation,molars in the treatment group were filled with 3M composite resin with visible light solidifying after acid etching while molars in the control group were filled with silver amalgam after routine oral preparation.Both groups were followed up to observe the occurrence of secondary caries,loosening and dropping of fillings and dental vertical fracture of the filled tooth 1 year and 2 years,respectively after the filling.Results：There was no significant difference between two groups in the occurrence of secondary caries,loosening and dropping of fillings and dental vertical fracture after 1 year（P0.05）.After 2 years,the occurrence of secondary caries,loosening and dropping of fillings and dental vertical fracture in the treatment group was significantly lower than those of the control group,with significant differences（P0.05）.Conclusions：3M composite resin can bear the occlusal force as the silver amalgam does.Meanwhile,it can avoid the occurrence of secondary caries and vertical fracture that caused by silver amalgam due to physical inlay.Furthermore,it provides rich operation time without wasting materials,and is free of mercury damage.
