Abstract
Objective: The objective of this study is to compare the cyclic fatigue resistance of nine types
of endodontic instruments of nickel–titanium.
Materials and Methods: Five files of 25 mm of length of each group: Reciproc (RC) R25; WaveOne
(WO) Primary; Unicone (UC) L25 25/0.06; K3XF 25/0.06; ProTaper Universal F2 (PTF2); ProTaper
Next X2 (PTX2); Mtwo 25/0.06; BioRaCe 25/0.06; One Shape L25 25/0.06 were subjected to a
cyclic fatigue resistance test on a mechanical apparatus. The mean fracture time was analyzed
statistically by one-way analysis of variance and Tukey’s honest significant difference post hoc
test, with significance set at P < 0.05.
Conclusion: It was observed that the groups PTX2, RC, R25, UC L25 25/0.06, and WO Primary
presented greater cyclic fracture resistance than the other groups (P < 0.001).
