Abstract :Purpose The aim of this study was to evaluate the retreatment abilities of the ProTaper Next insert ignore into journalissuearticles values(PTN); and F6 SkyTaper insert ignore into journalissuearticles values(F6); systems by using micro-computed tomography insert ignore into journalissuearticles values(micro-ct);, radiographic and microscopic imaging techniques. Materials and Methods The root canals of twenty-six extracted mandibular premolar teeth were prepared and obturated. For the retreatment procedure, the teeth were randomly divided into two equal groups according to endodontic instruments: PTN insert ignore into journalissuearticles values(X4); and F6 insert ignore into journalissuearticles values(#40/.06);. Pre- and post-operative filling material volumes were measured with micro-ct, and areas were measured with radiographic and microscopic imaging techniques. The percentages of residual material were calculated, and then statistically compared. The significance level was set at p<0.05. Results There was no statistically significant difference between F6 and PTN for retreatment efficacy in the micro-ct and radiographic imaging techniques insert ignore into journalissuearticles values(p>0.05);. PTN demonstrated better cleaning ability when evaluated by microscopic imaging. insert ignore into journalissuearticles values(p<0.05);. The correlation was moderate between micro-ct and radiographic, and micro-ct and microscopic imaging groups; however, it was strong between radiographic and microscopic imaging methods. Conclusion The PTN and F6 files had similar effects in the removal of filling material with micro-ct evaluation. The radiographic imaging method gave similar results with micro-ct imaging.
