Differences in Cyclic Fatigue Resistance Between ProTaper Next and ProTaper Universal Instruments at Different Levels

Journal of Endodontics, 2014
New designs and alloys have been developed to increase cyclic fatigue (CF) resistance of rotary files. The aim of this study was to compare CF resistance of ProTaper Universal (PTU; Dentsply Tulsa Dental, Tulsa, OK) and ProTaper Next (PTN, Dentsply Tulsa Dental) instruments at different points of curvature.A total of 420 files (240 PTU, S1, F1, F2, and
