Aim: The aim of the study was to evaluate the canal transportation and centering ability of rotary and reciprocating file systems using cone-beam computed tomography.
Materials and Methods: Mesiobuccal canals of sixty mandibular molars were selected for the study. Canals of length 19 mm, curvature of 10°–12°, and uncalcified with fully formed apex were selected. Canals were randomly divided into three groups of 20 teeth, and canal preparation with the WaveOne Gold, TruNatomy, and One Curve systems was performed according to the manufacturers' instructions. Cone-beam computed tomographic images were taken before and after instrumentation in the same position for comparative analysis.
Statistical Analysis Used: Apical transportation was calculated at the distances of 2, 3, and 4 mm from the apex. Tukey's post hoc test and unpaired “t”-tests were used to statistically analyze the data.
Results: WaveOne Gold caused less canal transportation and better-centering ability than TruNatomy and One Curve at all the three levels; there was a significant difference in canal transportation and centering ability among all the groups as well as all the three levels, i.e., 2, 3, and 4 mm from the apex.
Conclusion: WaveOne Gold (Reciprocating) reported less canal transportation and better-centering ability than rotary instruments TruNatomy and One Curve (Rotary) at all the three levels.
