Resin adhesion to dentin was first achieved in 1982 through mechanical hybridization between resin and collagen fibrils using an adhesive resin containing a functional monomer. Over the last 2 decades, newly developed adhesive resins have attempted to improve the bond strength at least in the first 24 h after bonding. Although much is known about the initial bond strength, learned through morphological analysis, the long-term durability of bonds has not yet been established analytically. However, numerous recent studies have shown chemical biodegradation of resin-dentin bonds under various testing regimes. In general, studies have shown that dentin bond strength decreases over time due to degradation of the resin and the collagen fibrils within the bonds. Furthermore, crystal formation around cured bonding resins has been reported in a number of adhesives after long-term water storage. However, the extent and process of degradation or crystallization is adhesive type specific. This review mainly summarizes the most recent and state of the art work in degradation of the bonding of dental restorative compounds with dentin based on micromorphological data of scanning and transmission electron microscopy.
树脂与牙本质的黏附最初于 1982 年通过在含有官能单体的黏合树脂中使树脂与胶原纤维之间产生机械性杂交而实现。在过去的 20 年中，新开发的黏合树脂一直试图至少在黏合后的最初 24 小时内提高黏合强度。尽管通过形态学分析已经了解了初始黏合强度，但尚未通过分析来确定黏合的长期耐久性。然而，最近的许多研究表明，在各种测试条件下，树脂-牙本质黏合会发生化学性降解。一般而言，研究表明，由于黏合中的树脂和胶原纤维降解，牙本质黏合强度随时间而降低。此外，在长期水储存后，一些黏合剂中已经报道了固化黏合树脂周围的晶体形成。然而，降解或结晶的程度和过程是黏合剂类型特异性的。本篇综述主要基于扫描和透射电子显微镜的微观形态学数据，总结了关于牙体修复复合材料与牙本质黏合降解的最新研究进展。
