Abstract

Aim of the study was to compare the removal of gutta-percha and bioceramic sealer using EdgeFile-XR (EF-XR) retreatment file system and PTU-RE files from mesial root from mandibular molars with mild to moderate curvature using Micro Computed Tomography (Micro-CT) imaging. EF-XR is a newly introduced retreatment file for removal of gutta-percha that has not been evaluated before. Sixteen anatomically matched mesial roots of mandibular molars with mild to moderate curvature were allotted into two groups (n = 8), ProTaper Universal Retreatment files (PTU-RE) and EF-XR. Root canal instrumentation and single cone obturation with BioRoot RCS sealer was performed. Following this, retreatment was done. Pre-and post-Micro-CT analysis was performed to determine the volume of remaining obturating material and root dentin removed and statistically analysed. Within the limitations of the present study, it can be concluded that PTU-RE retreatment files are better than EF-XR files for retrieval of gutta-percha and BioRoot RCS sealer.

EdgeFile-XR和ProTaper通用再处理文件去除杜仲胶和生物陶瓷密封剂的比较评价：微计算机断层扫描研究。

本研究的目的是比较使用EdgeFile-XR （EF-XR）再治疗文件系统和PTU-RE文件从轻度至中度弯曲的下颌磨牙近中根使用微计算机断层扫描（Micro- ct）成像去除胶过胶和生物陶瓷封口剂的效果。EF-XR是一种新引入的用于去除杜仲胶的再处理文件，以前没有对其进行过评估。将16例解剖匹配的轻度至中度弯曲下颌磨牙近中根分为ProTaper通用再治疗锉组（PTU-RE）和EF-XR组（n = 8）。采用BioRoot RCS密封器进行根管预备和单锥体封闭。在此之后，进行再处理。进行micro - ct前后分析，以确定剩余封闭材料和根牙本质去除的体积，并进行统计学分析。在本研究的限制下，可以得出结论，PTU-RE再处理文件比EF-XR文件更适合于检索杜胶和BioRoot RCS密封剂。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
