Nonsurgical endodontic retreatment consists of cleaning, shaping, and three­ dimensional filling of previously obturated root canals. It is the treatment of choice for the management of endodontic failures when access to the root canals is feasible. To successfully accomplish retreatment, all the obstructions preventing a direct access to the root canals need to be removed. For this study 60 freshly extracted human mandibular premolars with single canals were collected. These 60 teeth were endodontically treated and then again divided into 2 groups consisting of 30 samples each for retreatment. Of the two groups on one group retreatment was performed with RC solvent and other group without RC solvent. Efficacy of two nickel titanium instruments over H files with and without use of RC solvent in removal of gutta-percha in root canal retreatment was evaluated in this study. The amount of remaining gutta-percha was evaluated using image analysis software.
