Abstract

This study aimed to assess root canal irrigants' effect on the bond strength between endodontic sealers and root canal dentin, through a systematic review. The study protocol is available online (https://osf.io/x9tw4/). We selected studies considering the effects of root canal irrigants on sealer bond strength and comparing the influence of such agents used during the endodontic treatment and/or at final irrigation. The search was performed in the PubMed and Scopus databases. The screening was performed by two independent researchers. Data were extracted by one researcher and verified by another. A descriptive analysis was performed. A total of 39 studies were included. The majority demonstrated that using some irrigant substances such as ethylenediaminetetraacetic acid, maleic acid, phosphoric acid, and peracetic acid could improve, or at least not damage, the push-out bond strength. In opposition, a decrease in this outcome was observed when using only sodium hypochlorite or saline solution. The use of irrigant substances capable of demineralizing the surface of root canal dentin and/or removing the remnant smear layer seems to enhance, or, at least, does not compromise the push-out bond strength of the sealer to root dentin.

摘要

本研究旨在通过系统评价评估根管冲洗剂对牙髓封闭剂和根管牙本质之间粘合强度的影响。研究协议可在线获取 (https://osf.io/x9tw4/)。我们选择的研究考虑了根管冲洗剂对封闭剂粘合强度的影响，并比较了在牙髓治疗和/或最终冲洗期间使用的此类药物的影响。检索在 PubMed 和 Scopus 数据库中进行。筛选由两名独立研究人员进行。数据由一名研究人员提取并由另一名研究人员验证。进行了描述性分析。共纳入 39 项研究。大多数人证明，使用乙二胺四乙酸、马来酸、磷酸和过乙酸等一些冲洗物质可以改善、或者至少不会损坏推出的粘合强度。相反，当仅使用次氯酸钠或盐水溶液时，观察到该结果有所下降。使用能够使根管牙本质表面脱矿质和/或去除残留污迹层的冲洗物质的使用似乎增强了，或者至少不会损害封闭剂对根牙本质的推出粘合强度。
