Objective: To evaluate the resistance to fracture of rotary Ni-Ti files of various diameters and tapers after torsional stress simulation. Methods: Profile (Dentsply Maillerfer, Ballaigues, Suíça) instruments sizes 15 to 40, taper 0.04 and 0.06 were used. Ten instruments of each size and taper wer...
