Conclusion: the resin rags were fewer and shorter and the hybrid layers were thinner in sclerotic dentin than in normal dentin.
结论：硬化牙本质相对于正常牙本质形成的混合层较薄或者没有，树脂突短、少。
Conclusion: Bonding to sclerotic dentin is different from sound dentin, and may be compromised by the fewer resin tags and communications.
结论：硬化牙本质的粘接特性与正常牙本质存在差异。树脂突的数量及交通枝不足是硬化牙本质粘接强度受限的可能因素。
Sclerotic dentin, also named as transparent dentin, is a kind of reactive change of dentin, has great difference from normal dentin in structure.
硬化牙本质又被称作透明牙本质，是牙本质的一种反应性改变，在结构上与正常牙本质存在很大的差异。
The effect of the sclerotic dentin repaired with composite resin can be affected by the quality and quantity of hybrid layers and resin tags, and different etching systems and acid etching time.
混合层和树脂突的质和量以及不同的酸蚀系统和酸蚀时间都会影响硬化牙本质的复合树脂黏结修复效果。
