Introduction: The aim of this in vitro study was to compare the cyclic fatigue resistance and torsional resis-tance of EdgeTaper Platinum (ETP) with those of Pro-Taper Gold (PTG) at simulated body temperature.

Methods: ETP and PTG files with #25 tip size were selected. Cyclic fatigue tests were performed in a stain-less steel artificial canal until file fracture occurred. The time to fracture was recorded. For the torsional resis-tance testing, the apical 5 mm of the file was firmly secured with acrylic resin, and the assembly was fixed over torque gauge device. A uniform torsional stress was applied with continuous rotation motion until frac-ture occurred. The torque at failure was recorded. Both experiments were conducted at 35  1

C. Fractured sur-faces were tested via scanning electron microscopy. Sta-tistical analysis was performed using independent Student t test at 5% significance level.

Results: The ETP had superior cyclic fatigue resistance than PTG (P < .01). However, it exhibited lower torsional resis-tance (P < .05). The ETP and PTG showed typical fea-tures of cyclic and torsional fatigue behavior under scanning electron microscopy.

Conclusions: The ETP exhibited superior resistance to cyclic fatigue but failed to show any improvement in the torsional resistance compared with PTG. (J Endod 2019;45:611–614)
