树脂-牙本质粘结强度耐久性测试已被广泛用于评价粘结剂系统的有效性和改善该性能的新策略的适用性。临床有效性由放置在非龋性宫颈病变（NCCL）中的修复体的存活率决定。虽然有证据表明，实验室研究中产生的粘结强度数据与NCCL牙本质修复的临床结果存在某种相关性，但从实验室测试中获得的粘结机制知识是否可用于证明树脂-牙本质粘结的临床性能仍存在疑问。体外试验中使用的粘合基质与NCCL中遇到的基质之间存在显著的形态和结构差异。这些差异使NCCL有资格作为粘结的敌对基质，产生的粘结强度通常低于正常牙本质中获得的粘结强度。然而，NCCL漂白的临床存活时间往往超过实验室测试的正常牙本质的耐久性。同样，关于后路复合材料置换的长期存活率的临床报告与实验室研究中报告的粘合界面相对快速的降解率相矛盾。本文批判性地分析了目前如何衡量粘合剂系统的有效性，以确定可以鼓励新研究的知识差距。对临床使用多年但因牙周原因拔除的牙体中树脂复合材料牙体的粘接界面进行形态学和化学分析，可以作为观察临床可接受的牙体超微结构特征的有用工具。这可以帮助确定对于临床成功而言，降解程度是可接受的。
Resin-dentin bond strength durability testing has been extensively used to evaluate the effectiveness of adhesive systems and the applicability of new strategies to improve that property. Clinical effectiveness is determined by the survival rates of restorations placed in non-carious cervical lesions (NCCL). While there is evidence that the bond strength data generated in laboratory studies somehow correlates with the clinical outcome of NCCL restorations, it is questionable whether the knowledge of bonding mechanisms obtained from laboratory testing can be used to justify clinical performance of resin-dentin bonds. There are significant morphological and structural differences between the bonding substrate used in in vitro testing versus the substrate encountered in NCCL. These differences qualify NCCL as a hostile substrate for bonding, yielding bond strengths that are usually lower than those obtained in normal dentin. However, clinical survival time of NCCL restorations often surpass the durability of normal dentin tested in the laboratory. Likewise, clinical reports on the long-term survival rates of posterior composite restorations defy the relatively rapid rate of degradation of adhesive interfaces reported in laboratory studies. This article critically analyzes how the effectiveness of adhesive systems is currently measured, to identify gaps in knowledge where new research could be encouraged. The morphological and chemical analysis of bonded interfaces of resin composite restorations in teeth that had been in clinical service for many years, but were extracted for periodontal reasons, could be a useful tool to observe the ultrastructural characteristics of restorations that are regarded as clinically acceptable. This could help determine how much degradation is acceptable for clinical success.
