| 摘 要： | 目的扫描电镜观察化学机械去龋对牙本质粘结效果的影响。方法观察比较化学机械去龋和慢速球钻去龋后牙本质表面以及牙本质和4种粘结系统粘结界面的超微结构。结果与球钻去龋相比，化学机械去龋后的牙本质表面玷污层少，牙本质和Prime＆Bond NT（PB）＋复合体的粘结界面出现树脂突结构，和Adper Prompt-L-Pop（AP）＋树脂的粘结界面中树脂突更密集，混合层更致密、均一。结论从超微结构上看，化学机械去龋技术有利于牙本质的粘结。

| Abstract: | OBJECTIVE: To observe the influence of chemomechanical caries removal on dentin adhesion by scanning electron microscope. METHODS: The ultrastructure of dentin surfaces and adhesives-dentin bonding interfaces after caries removal by chemomechanical method or drilling were observed. RESULTS: Less smear layer in dentin surface, resin tags in the interface between dentin and Prime&Bond NT/compomer and numerous resin tags and more uniform and closer hybrid layer in the interface between dentin and Adper Prompt-L-Pop/composite were found in chemomechanical preparation than in drilling preparation. CONCLUSIONS: Chemomechanical caries removal can benefit dentin adhesion. |
