INTRODUCTION
Retreatment of endodontically treated teeth is a challenge that requires complete removal of the previous filling material. Several techniques are indicated for this procedure. The present review tries to identify the most efficient method for extirpation of Resilon (RS) root fillings and to compare the speed and efficacy of RS and gutta-percha (GP) root filling removal.
METHODS AND MATERIALS
Three trained evaluators conducted a search through three major databases (PubMed, Cochrane Library and Lilacs) over the articles published in the period from 2001 to 2014. The search keywords were Epiphany Sealer, Resilon, Retreatment and Removal Procedure.
RESULTS
Twelve articles were included in the final sample (three in vitro studies and nine randomized trials).
CONCLUSION
The ProTaper (manual or rotatory) system in combination with chemical solvents is the most efficient method for removing Resilon root filling. Retreatment of Resilon is more rapid and associated with less remnants of debris.
引言
对经过牙髓治疗的牙齿进行再治疗是一项挑战，需要完全去除先前的填充材料。该过程有多种技术可供选择。本综述旨在确定去除Resilon（RS）根管充填物的最有效方法，并比较去除RS和牙胶尖（GP）根管充填物的速度和效果。
方法和材料
三名经过培训的评估人员通过三个主要数据库（PubMed、Cochrane图书馆和Lilacs）检索了2001年至2014年期间发表的文章。检索关键词为Epiphany封闭剂、Resilon、再治疗和去除程序。
结果
最终样本纳入了12篇文章（3篇体外研究和9篇随机试验）。
结论
ProTaper（手动或旋转）系统结合化学溶剂是去除Resilon根管充填物的最有效方法。Resilon的再治疗更快，且残留碎屑更少。
