摘要：

目的采用扫描电镜观察涂用脱敏剂的牙本质的微观特征，评价脱敏剂对树脂粘接剂粘接强度的影响。方法对离体正畸牙进行常规牙体预备，分别涂用Gluma系统处理剂、Single Bond 2脱敏剂、BisBlockTM脱敏剂，用扫描电镜观察牙本质表面和剖面的微观特征。用树脂粘接剂把铸件粘接到经脱敏剂处理的牙本质表面，测定样本的剪切强度，用SPSS 13.0软件进行统计学分析。结果Gluma组牙本质小管开口几乎堵塞；Single Bond 2组牙本质表面形成厚的树脂层；BisBlockTM组牙本质小管开口部分堵塞。BisBlockTM组剪切强度最大，为（13.04±2.76）MPa，与对照组相比，其差异有统计学意义（P<0.05）。结论Gluma系统处理剂、Single Bond 2脱敏剂、BisBlockTM脱敏剂能够堵塞牙本质小管开口。BisBlockTM脱敏剂可以增强树脂粘接剂的粘接强度。

Abstract:

Objective To observe the microscopic characteristic of the dentinal surface and cross section after using dental desensitizer, and evaluate the effect of the dental desensitizer on the shear strength of resin cements. Methods To use the dental desensitizer（Gluma, Single Bond 2, BisBlockTM） individually on the prepared human bicuspid teeth which were extracted for orthopaedics. The microscopic characteristic of the dentinal surface and cross section were observed with scanning electron microscope（SEM）. The adhered posts to the teeth pretreated with desensitizer were bonded with resin cements. The shear strength was measured and data was analyzed by SPSS 13.0 statistics software. Results The orifices of dentinal tubule were mostly occluded in Gluma samples and partly occluded in BisBlockTM samples. Resin layer was observed in Single Bond 2 samples. BisBlockTM group gathered the best shear strength, the shear strength value was （13.04 ±2.76）MPa. Marked statistic difference were found when compared with control group. Conclusion Gluma, Single Bond 2 and BisBlockTM can block the orifices of dentinal tubule. BisBlockTM enhanced the bonding strength of the resin cements.
