| 摘 要： | 目的:通过微拉伸黏结强度实验,检测Nd:YAG激光联合3种不同黏结系统处理的硬化牙本质与复合树脂的黏结强度。方法:选择15颗硬化牙本质视觉分级为3级以上的面磨损牙,将面硬化牙本质分为面积近似相等的两部分,随机分为A(A1、A2)、B(B1、B2)、C(C1、C2)3组,以1W、10Hz Nd:YAG激光处理硬化牙本质表面后,按照随机数字表,使每颗牙分割的两部分进入不同的处理组,A2、C1联合ScotchbondTM处理,Z350复合树脂充填;A1、B1联合Adper Prompt L-Pop处理,Z350复合树脂充填;B2、C2联合Clearfil SE Bond处理,Z350复合树脂充填。置于37℃生理盐水中24h后,制作微拉伸试件,测试黏结强度,在体视显微镜下观察断裂模式并分类。采用SPSS13.0软件包对试件微拉伸黏结强度值做单因素方差分析。结果:Nd:YAG激光联合3种黏结剂处理后的微拉伸黏结强度分别为ScotchbondTM(A2、C1)处理组(22.96±4.93)MPa,Adper Prompt L-Pop(A1、B1)处理组(18.73±4.71)MPa,Clearfil SE Bond(...

| Abstract: | PURPOSE:To investigate the influence of Nd:YAG laser on micro-tensile bond strength of different adhesive systems to non-carious sclerotic dentin. METHODS:Fifteen human occlusal wearing molars which were above degree three were selected and cut into nearly equal halves,divided into A(A1,A2),B(B1,B2) and C(C1,C2) three groups at randomly. Then the teeth were processed with Nd:YAG laser (1W,10Hz),teeth in A2 and C1 were combined with ScotchbondTM,A1 and B1 were combined with Adper Prompt L-Pop,and B2 and C2 w... |
