Abstract :Purpose The purpose of the present study is to assess the rate of newly formed microcracks comparatively during root canal instrumentation by using ProTaper Next, Reciproc, and Self-Adjusting File systems using micro-computed tomography. Subjects and Methods Thirty mesial roots of mandibular molars were randomly assigned to 3 experimental groups insert ignore into journalissuearticles values(n = 10); as follows, ProTaper Next, Reciproc and Self-Adjusting File system. Preoperative and postoperative scans were obtained at the isotropic resolution of 13.68 μm. Cross-section images were examined to identify the presence of newly formed dentinal microcracks. Results The Self-Adjusting File and Reciproc systems caused a higher rate of new microcrack formation than the ProTaper Next group insert ignore into journalissuearticles values(p < 0.001);. There were also significant differences in the new microcrack formation between Reciproc and Self-Adjusting File groups insert ignore into journalissuearticles values(p < 0.001);. Conclusion Reciproc and Self-Adjusting File systems caused a higher rate of newly formed microcraks compared to ProTaper Next system.
