Summary: | PurposeThe purpose of the present study is to assess the rate of newly formed microcrackscomparatively during root canal instrumentation by using ProTaper Next, Reciproc,and Self-Adjusting File systems using micro-computed tomography.Subjects and MethodsThirty mesial roots of mandibular molars were randomly assigned to 3 experimentalgroups (n = 10) as follows, ProTaper Next, Reciproc and Self-Adjusting File system.Preoperative and postoperative scans were obtained at the isotropic resolution of13.68 μm. Cross-section images were examined to identify the presence of newlyformed dentinal microcracks.ResultsThe Self-Adjusting File and Reciproc systems caused a higher rate of new microcrackformation than the ProTaper Next group (p < 0.001). There were also significantdifferences in the new microcrack formation between Reciproc and Self-AdjustingFile groups (p < 0.001).ConclusionReciproc and Self-Adjusting File systems caused a higher rate of newly formedmicrocraks compared to ProTaper Next system. |
