摘　　要：目的 比较髓腔内使用两种牙本质小管阻塞剂阻塞牙本质小管的效果。方法 选择90颗离体单根管牙经常规根管清理成形后,随机分为3组(其中1组为对照组),两实验组在髓腔内使用草酸钾或光固化粘接剂,用染料渗透法观察比较染料浸入牙本质的情况。结果 两实验组与对照组相比其染料浸入牙本质的情况有极为显著性差异(P<0.01)。结论 在髓腔内使用牙本质小管阻塞剂可以有效地阻止染料渗入牙体。Objective To compare the effect of two methods(dipossium oxalete and light-cured adhesive) on obstructing the dentinal tubules. Methods 90 monoroot canal extracted teeth were randomly divided into 3 groups(one of them was control group, the others were experiment groups) after routine root canal preparation. Two different obstructing agents were applied into the pulp chambers and the dye penetration mathod was used to compare the depths which the dyestuffs penetrated into the dentinal tubules. Results Statistically significant differences were founded among experiment groups and contral group. Conclusion Ap- plying the dentinal tubule blocker could effectively prevent dyestuffs from penetration.
