This study aimed to evaluate the efficacy of supplementary methods to remove the remaining root filling material from root canals. Twenty mandibular single-rooted teeth were instrumented with Reciproc 25/0.08 and filled with gutta-percha and AH-Plus sealer, followed by a micro-CT scanning. The retreatment procedures were performed, the samples were rescanned and divided into two groups (n = 10) according to the supplementary method: XP-endo Finisher R and Clearsonic tip. The samples were rescanned and the volume of remaining root filling material was quantified. Data were analysed statistically (P < 0.05). The amount of filling material removed after supplementary methods was higher compared with retreatment procedure (P < 0.05). XP-endo Finisher R promoted a greater percentage of filling materials reduction in the entire root canal and apical third compared with Clearsonic tip (P < 0.05). Supplementary methods were effective in the reduction of root filling materials. XP-endo Finisher R removed more root filling material than Clearsonic tip.
本研究旨在评估辅助方法去除根管内残留根充材料的效果。选取20颗下颌单根牙，使用Reciproc 25/0.08进行根管预备，并用牙胶尖和AH-Plus封闭剂充填，随后进行显微CT扫描。进行再治疗操作，对样本再次扫描，并根据辅助方法分为两组（n = 10）：XP-endo Finisher R组和Clearsonic尖组。再次扫描样本并对残留根充材料的体积进行量化。对数据进行统计学分析（P < 0.05）。与再治疗操作相比，辅助方法去除的充填材料量更多（P < 0.05）。与Clearsonic尖相比，XP-endo Finisher R在整个根管和根尖三分之一处促进充填材料减少的百分比更高（P < 0.05）。辅助方法在减少根充材料方面有效。XP-endo Finisher R比Clearsonic尖去除的根充材料更多。
