Comparison of Glide Path and Pathfiles in Canal Preparation by Cone-beam Computed Tomography: An Original Research

INTRODUCTION: Endodontics has become a routine practice in the recent times and many recent advanced rotary systems are available commercially. Hence, in our study, we describe the canal transportation of the different file systems in various combinations of the “Glide path (Gp)” by cone-beam computed tomography (CBCT). MATERIALS AND METHODS: In vitro study was with 40 single-rooted extracted human teeth that were grouped as “Group 1: Pathfiles (PF) and Group 2: V Gp 2 (V2).” Measurement of Centric ability, canal transportation, root canal curvature of the CBCT images was compared of the pre and the postpreperation of the canals with the two systems. RESULTS: PF showed greater curvatures, working time, canal transportations, compared to the V2. PF showed lesser centric ratio, removed greater dentine compared to the V2 and also the cross-sectional area was also greater for the PF than V2. CONCLUSION: V2 performed superiorly than PF showing lesser canal transportation.
