Abstract

Objective

To determine whether bond strength to eroded dentin is similar to values found for sound dentin, before and after additional treatments.

Materials and methods

MeSH terms and keywords relative to the topics ‘adhesion to dentin’ and ‘eroded dentin’ were searched in the Pubmed and the Scopus databases. In vitro studies that compared the bond strength to sound and eroded dentin were selected. The following data were included: pH-cycling model, materials, treatments, bond strength tests, and failure modes. Bond strength values were compared by meta-analyses and the failure modes were analyzed for random effects.

Results

The bond strength data of the 23 studies included were extracted by the reviewers and assessed by meta-analyses. Low risk of bias was found most frequently. Sound × Eroded Dentin comparisons revealed higher bond strength to sound dentin. When compared with untreated eroded dentin, treatments such as NaOCl, E64, CHX and PAA acid, PPA and RI primer, showed high and durable bond strength values (p˂0.0001). Mixed failures were the most frequent type (39.26%), followed by adhesive (38.21%) and cohesive failures (6.15%).

Conclusions

The bond strength to eroded dentin can be improved by mechanical and chemical strategies, applied before or during the adhesive protocol.

Clinical significance

Eroded teeth, an increasingly frequent clinical condition found, require restorations with adhesive protocols that result in favorable and durable bond strength over time.

树脂基材料与侵蚀牙本质的粘附：系统评价和荟萃分析

摘要

客观的

确定在额外处理之前和之后与侵蚀牙本质的粘合强度是否与健全牙本质的值相似。

材料和方法

在 Pubmed 和 Scopus 数据库中搜索了与主题“牙本质粘附”和“侵蚀牙本质”相关的 MeSH 术语和关键词。选择了将粘合强度与健全和侵蚀牙本质进行比较的体外研究。包括以下数据：pH 循环模型、材料、处理、粘合强度测试和失效模式。通过荟萃分析比较了结合强度值，并分析了失效模式的随机效应。

结果

纳入的 23 项研究的粘合强度数据由审稿人提取并通过荟萃分析进行评估。最常发现低偏倚风险。Sound × Eroded Dentin 比较显示与健全牙本质的粘合强度更高。与未经处理的侵蚀牙本质相比，NaOCl、E64、CHX 和 PAA 酸、PPA 和 RI 底漆等处理显示出高且持久的粘合强度值 ( p˂0.0001 )。混合失效是最常见的类型（39.26%），其次是粘合剂（38.21%）和内聚失效（6.15%）。

结论

与侵蚀牙本质的粘合强度可以通过在粘合协议之前或期间应用的机械和化学策略来提高。

临床意义

腐蚀牙齿是一种越来越常见的临床病症，需要使用粘合剂协议进行修复，从而随着时间的推移产生良好且持久的粘合强度。
