自酸蚀粘结剂联合流体树脂修复楔状缺损的疗效观察

Effect research of clinical dental wedge-shaped defects be fulled by self-etching adhesive and flowable resin

目的:探讨自酸蚀粘结剂联合流体树脂修复楔状缺损的疗效。方法:对21例患者共126颗牙髓活力正常的牙颈部楔状缺损分别进行充填治疗,随机分成实验组和对照组,每组63颗牙。实验组使用CLEARFIL S3 BONDTM自酸蚀粘结剂和流体树脂进行充填;对照组常规酸蚀,涂布粘结剂和复合树脂充填。评价两组6个月、1年、2年的保留成功率。结果:两组在治疗后6个月,成功率差异无统计学意义;治疗后2年,自酸蚀粘结剂联合流体树脂充填成功率为95%,对照组为76.6%,两组差异有统计学意义(P<0.01)。结论:自酸蚀粘结剂和流体树脂充填楔状缺损牙髓刺激性小,可明显提高修复充填体的固位率,值得推广应用。

ObjectiveTo study the clinical effect of self-etching adhesive（CLEARFIL S3 BONDTM） and flowable resin on restoring dental wedge-shaped defects． Methods A total of 126 teeth with wedge-shaped defect were divided into 2 groups randomly．Test group was treated by CLEARFIL S3 BONDTM and flowable resin while the control was restored by 3M FiltekTM Z350 compomer．The clinical effects after two years were compared． Results There was nosignificant difference between two groups of success rate （P＞0.05） after 6 months. But two years later,the success rate of flowable resin was 95.0％,while the control group was 76.6％.There was significant difference between two groups（P＜0.01）．ConclusionCLEARFIL S3 BONDTM and Flowable resin exhibited better clinical efect than 3M FiltekTM Z350 compomer during our study period，which makes it a good choice for treating dental wedge-shaped defects.
