摘　　要：目的:评价自酸蚀黏结剂XenoⅢ在不同涂擦方式下对离体牙牙本质通透性的影响。方法:将面处理过的50例新鲜拔除的离体牙随机均分为5组,用不同的涂擦方式(方向、力度)将自酸蚀黏结剂XenoⅢ涂擦于处理过的离体牙面。暴露处理面,其余部分用指甲油封闭,将离体牙浸泡于20 g/L的亚甲蓝液中6 h,然后剖开离体牙,根管显微镜下测量染料渗入深度。结果:涂布自酸蚀黏结剂的各实验组染料渗透值均明显小于空白对照组(P<0.05),其中同向轻涂组最小,与其他3组间均有统计学差异(P<0.05)。结论:同向轻涂自酸蚀黏结剂XenoⅢ时离体牙牙本质的通透性最低。AIM：To evaluate the influence of self-etching adhesive Xeno Ⅲ on the permeability of dentin with different brushing ways in vitro. METHODS： Fiflly extracted teeth were divided randomly and averagely into five groups. Self-etching adhesive Xenom was coated on the ocelusal surfaces of the extracted teeth with different brushing ways （direction and force）. The treated surface was exposed and the rest was sealed. The extracted teeth were immersed in the methylene blue solution for six hours and vertically cleaved into two sections. The penetrating depth of the dye was measured under a dental microscope. Finally, the statistical analysis of measurement results was carried out. RESULTS： Every group painted by self-etching adhesive had significant differences from the blank control group（ P 〈 0.05 ）. The group painted gently in the same direction had significant differences from the rest painted by self-etching adhesive （P 〈 0.05 ）. CONCLUSION ： This in vitro experiment showed that the permeability of dentin painted gently in the same direction in vitro was the lowest.
