A Cone-Beam Computed Tomography Imaging-Based Comparative Study on Root Canal Preparation Using Three Different Nickel-Titanium Instruments

Objective: The goal of this study is to use cone-beam computed tomography (CBCT)-based three-dimensional (3D) imaging to compare the performance of three nickel-titanium instruments, namely, Mtwo, ProTaper Universal, and ProTaper. Next, in the preparation of the curved mesiobuccal root canal of the maxillary first molar. Conclusion: In root canal preparation, the ProTaper Next nickel instrument generates a moderate degree of dentin removal and is associated with the least transportation in the apical segment, which is the most crucial region.
