Objective: To evaluate the effect of adaptive motion on shaping ability of Twisted Files nickel-titanium files in simulated S-shaped canals.Methods: Forty S-shaped canals in resin blocks were prepared to an apical size of 0.25 mm using Twisted Files with rotary or adaptive motion (n=20 canals/group).Composite images were made from the superimposition of pre-and post-instrumentation images.The amount of resin removed by each system was measured by using a digital template and image analysis software.Canal aberrations were also recorded.The data were statistically analyzed by using Mann-Whitney U test.Results: There was no significantly difference between adaptive and rotary motion groups (P > 0.05).No instrument fracture or canal aberrations were inspected during canal preparation.Conclusion: Within the limitation of the present study, adaptive and rotary motions were safe to use and were able to prepare the canals efficiently.
