Aim: The present in-vitro study compared the shaping effects like original canal curvature preserving ability and transportation of canal lumen following root canal preparation by three rotary single file systems, Reciproc, WaveOne, and OneShape, in teeth with curved root canals using cone-beam computed tomographic imaging technique.
Materials and Methods: Sixty mesiobuccal roots of mandibular first molars extracted for periodontal reasons with completely formed root apex having canal length of at least 18mm, with canal curvature of 15?–30? (Schneider method) from middle level of root length, were selected for this study. Samples were randomly divided into 3 groups according rotary file used in canal preparation namely; Reciproc (VDW, Munich, Germany), WaveOne (Dentsply Maillefer, Ballaigues, Switzerland), and OneShape (Micro Méga, Besançon, France) systems, with 20 teeth each. Diagnostic and post instrumentation Cone-beam computed tomography (CBCT) radiographs were taken for each sample. Apical transportation was calculated at distances of 2mm, 3mm, and 4 mm from the root apex. The data were tabulated and statistically analyzed using analysis of variance (ANOVA) and post-hoc Tukey’s HSD test and level of significance was set at a p value <0>
Results The mean canal transportation was found to be significantly lower with OneShape (p<0>
Conclusions: The OneShape rotary system showed the lowest transportation of canal lumen in both the mesiodistal and buccolingual directions and the highest centering ability contrary to the Reciproc system, which showed the highest transportation and the lowest centering ability.

Keywords: OneShape, Reciproc, Root canal preparation, Single file, Transportation, WaveOne.
