| 目的：观察新型激光光敏根管消毒剂、甲苯胺蓝和亚甲基蓝在牙本质中的渗透效果，评价三种光敏剂在牙本质中的渗透性。
方法：收集新鲜拔除的离体单根管牙90 颗，根管预备后随机分为三组。每组30 颗。A组为新型激光光敏根管消毒剂组；B 组为甲
苯胺蓝组；C 组为亚甲基蓝组。A、B、C 三组实验根管内分别用浸有饱和的新型激光光敏根管消毒剂、甲苯胺蓝和亚甲基蓝的棉捻
在根管内停留60 秒。沿牙体长轴颊舌纵向劈开，倒置荧光显微镜下观察并拍照，用Photoshop8.01 软件测量三种光敏剂渗透入牙
本质的平均深度。结果：新型激光光敏根管消毒剂在牙本质内的渗透平均深度为553.25 um，甲苯胺蓝在牙本质内的渗透平均深
度为350.75 um，亚甲基蓝在牙本质内的渗透平均深度为168.25 um。结论：新型激光光敏根管消毒剂在牙本质渗透性明显优于甲
苯胺蓝和亚甲基蓝，具有良好的牙本质渗透性。 |

| Objective:To evaluate the permeability of three different kinds of laser photosensitizer in the root canal dentinal.Methods:90 single-rooted human teeth were randomly divided into 3 groups after root canal preparing. (Agroup was laser photosensitizer
disinfection reagent; B group was toluidine blue; C group was methylene blue. ). Experimental groups were dipped for 60 seconds by
different laser photosensitizer Penetration depth of the three groups were measured by inverted fluorescent microscope after separating
tooth along the axis.Results:The penetration depth of group A was 553.25 um. B was 350.75 um. C was 168.25 um.Conclusion:The
new laser photosensitizer's permeability was better than toluidine blue’and methylene blue'. |
