Comparative evaluation of retreatment techniques by using different file systems from oval-shaped canals

Abstract

MTwo^® R with solvent and ultrasonics, R-Endo^®, and R-Endo^® with solvent and ultrasonics were effective in gutta-percha removal from coronal third, middle third, and apical third, respectively. Significance: Nonsurgical endodontic retreatment using rotary files helps in gaining access to infected teeth. During retreatment procedure, this helps disinfectant to reach in critical areas of the root canal system, thereby decreasing the microbial load, leading to achieve healthy periradicular tissues.
