Using Cone-Beam Computed Tomography to Evaluate Apical Transportation and Centering Ability of WaveOne, OneShape, and Tornado Rotary Systems: A Clinical Study


Abstract This clinical study was aimed to evaluate apical transportation and centering ability of WaveOne, OneShape files and Tornado rotary system using Cone-beam computed tomography (CBCT). Lower molars with a curving angle of buccal canals extending from 15°-45° in 24 patients were arbitrarily divided into three groups (n=8) rendering to the rotary systems used: Group 1, Tornado system, Group 2, WaveOne rotary system, and Group 3, OneShape rotary system. CBCT was used as a diagnostic method to evaluate centering ratio and canal transportation at 2, 5 and 8 mm from apical foramen. One-way analysis of variance and post hoc Tukey tests were used for statistical analysis at p≤0.05. No statistically significant difference in the magnitude of transportation and centering ability was found at all tested levels (P>0.05). WaveOne and OneShape nickel-titanium files and Tornado stainless-steel file conserved the original canal curvature with no significant variance.
