Objectives: The aim of the present study was to evaluate the fatigue resistance of FlexMaster and MTwo used in continuous rotation and in alternate movement, and the influence of various parameters on this. Materials and methods: Forty FlexMaster and 20 MTwo were used, and subjected to fatigue test. Results: Statistically significant differences were found among all groups. Conclusions: Lower taper leads to increased resistance to cyclic fatigue of the instrument. Alternate rotation increases the average life of the instrument, and gives greater resistance to cyclic fatigue to those with similar taper. © 2012 Società Italiana di Endodonzia.
