摘　　要：目的探讨Carisolv处理牙本质后对树脂充填后微渗漏的影响。方法选择单根管离体牙30颗,将面制备成约3×3×3mm的窝洞。随机分为3组,每组10颗,实验组分别选用Carisolv、350g/L磷酸处理窝洞,对照组不作任何处理,然后使用Prime&Bond NT粘结剂及复合树脂(Chrisma A2)直接进行树脂充填修复。经500次冷热循环后行印度墨水染色1周,体视显微镜下观测各充填体边缘微渗漏的长度。结果 Carisolv组树脂充填后微渗漏较酸蚀组严重,差异有统计学意义(P﹤0.05),Carisolv组微渗漏低于对照组,但差异无统计学意义(P﹥0.05)。结论 Carisolv处理牙本质后对树脂充填后微渗漏有一定影响。OBJECTIVE To study the effects of Resin micro-leakage after Carisolv processing dentin. METHODS Thirty ex- tracted human single-rooted teeth were collected, and occlusal surfaces were prepared hole into 3×3 ×3mm. Specimens were randomly divided into 3 groups, the experimental group were chosen Carisolv, 350 g/L phosphoric acid was used to process the holes, while the control group with nothing, then the Prime＆Bond NT and Composite resin （ChrismaA2） was used to repair the holes directly. After 500 thermal cycling, all specimens were immersed in Indian ink for one week and the penetration depth was examined under stereo microscope. RESULTS The Carisolv group was more serious than the etched group, and there was statistically significance （P 〈 0.05）, but was less than that of the control group （P 〉 0.05）. CONCLUSION There was a cer- tain effect on the Resin micro-leakage after Carisolv Processing dentin.
