In Vitro Comparison of Cyclic Fatigue Resistance of ProTaper, WaveOne, and Twisted Files

Abstract Introduction The aim of this study was to compare the cyclic fatigue resistance of 3 nickel-titanium (NiTi) endodontic instruments from ProTaper, WaveOne (WO), and Twisted Files (TF). Methods Cyclic fatigue testing was conducted by operating instruments from ProTaper F2, WO 25 .08, and TF 2...

Zusammenfassung:	Abstract Introduction The aim of this study was to compare the cyclic fatigue resistance of 3 nickel-titanium (NiTi) endodontic instruments from ProTaper, WaveOne (WO), and Twisted Files (TF). Methods Cyclic fatigue testing was conducted by operating instruments from ProTaper F2, WO 25 .08, and TF 25 .08. A total of 184 instruments were rotated in 4 curved artificial canals with different angles and radius of curvature. The time and cycles to failure were calculated. The data were compared for differences by using 2-way analysis of variance ( P
