龋病影响牙本质自酸蚀粘接修复的研究进展

Research progress on self-etching adhesive system in the bonding of caries-affected dentin

自酸蚀粘接系统适用于牙本质和釉质的粘接,具有操作简单、修复体边缘封闭性良好、术后敏感低等优点,有很好的发展前景。在临床工作中,龋坏引起的牙体缺损是临床修复的主要内容。临床上,医生在去除龋坏时,建议只去除细菌入侵的那部分牙本质,而已脱矿却无细菌入侵的牙本质,即龋坏影响牙本质(CAD),是临床粘接的主要部分。与正常的牙本质相比较,CAD的矿化度较低,与树脂的粘接效果可能不尽相同。本文就自酸蚀粘接系统用于CAD的粘接修复作一综述,以期推广其在国内临床上的应用。

Self-etching adhesive system has good prospects in the adhesive of dentin and enamel with its advantages of easily operating,good sealing characteristic of the restoration margin and low technique sensitivity.In the clinic,dental defect resulting from caries is the main component of restoration.Dentists supposed that cariesinfected dentin should be removed,but the dentin demineralization without bacterial invasion（caries-affected dentin,CAD） should be reserved.CAD is the major proportion in bonding.The mineralization of CAD is lower than the normal dentin,which may lead to a different resin bond effect between CAD and normal dentin.This paper reviewed the research progress on the role of self-etching adhesive system in the bonding of CAD,contributing to popularize its internal clinical application.
