Canal-Centering and Apical Transportation Ability of Similar Cross-Section NiTi Instruments Working with Different Kinematics-Micro-CT-based Analysis.

Objective: Evaluating the canal-centering and apical transportation ability of endodontic file systems working with different kinematics but of similar cross section.

Materials And Methods: Sixty human maxillary first molar mesiobuccal (MB) roots were assigned to three experimental groups based on instrumentation techniques: Reciproc Blue (RB), Mtwo (M2), and OneShape (OS). Pre- and post-instrumentation micro-computed tomographic analysis was performed.
