牙本质处理剂对粘结影响的扫描电镜观察

The Scanning Electron Observaions on Bonding Effects of Dentine Primer

应用扫描电镜观察使用两种不同牙本质粘结系统的树脂与牙本质粘结情况。结果发现：粘结界面有广泛密集的树脂突形成，树脂突又有旁侧分枝，彼此相连成网状，产生良好的机械固位。讨论分析了牙本质处理剂的作用，对于是否要去除玷污层，应视牙本质处理剂的种类与性质而定。

The bonding between resin and dentine with two different dentine systems was observed under scanning electron microscopy.The results showed that there were estensive resin tags with branches,which created a better mechanical retention,and whether the smear layer should be removed depended on the kind and function of dentine primer.
