摘要
目的:评价自酸蚀黏结剂 I bond 在不同涂擦方式下对离体牙牙本质通透性的影
响。方法:将合面预处理过的 25 例新鲜拔除的离体牙随机平均分为 5 组,各组用
不同的涂擦方式(主要区别力度、方向)将自酸蚀黏结剂 I bond 涂擦于预处理过的离体
牙合面上,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 24 h,然后剖开离体牙,在体式牙科显微镜下测量染料渗入的深度。结果:涂

涂组最小,与其他 3 组间均有统计学差异(P<) 结论:同向轻涂自酸蚀黏结剂 I
bond 时离体牙的牙本质的通透性最低。

Effect of Self-etching Adhesive I Bond on the
Permeability of Dentin with Different Brushing Ways
in Vitro
Postgraduate: Zhang xuan Supervisor: Ass Prof. Wu peiling
Abstract
Objective: To evaluate the influence of self-etching adhesive I bond on the
permeability of dentin with different brushing ways in vitro. Methods: Twenty-five
extracted teeth were divided randomly and averagely into five groups. Self-etching
adhesive I bond was coated on the occlusal surfaces of the extracted teeth with different
brushing ways (force and direction). The treated surface was exposed and the rest was
sealed. The extracted teeth were in-mersed in the ethylene blue solution for twenty-four
hours and vertically cleaved into two sections. The rating 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 <). The group painted gently
in the same direction had significant differences from the rest painted by self-etching
adhesive (P < ). Conclusion: This in vitro experiment showed that the permeability of
dentin painted gently in the same direction in vitro was the lowest.
