Abstract

Aims: The aim of the present study is to evaluate and compare the cyclic rotations needed to fracture three different rotary nickel titanium endodontic instruments namely Neo Endo S, Endo Plus and Hyflex EDM

Materials and Methods: Three NiTi rotary file systems (Neo Endo S, Endo Plus and Hyflex EDM) size #25, 0.6 % taper were used in the study. The instruments were inspected before used for any defects. A static cyclic fatigue testing device was customized for this study. It consists of a metal framework of iron and wood. The files were experimentally divided into three groups. The cyclic fatigue test of all the instruments was performed by one operator.

Statistical analyses were performed with one-way ANOVA (P=0.05).

Results: No of cyclic fatigue value of Hyflex EDM group was significantly higher than No of Cyclic fatigue values of endo plus and neo endo S groups. Group I showed more cyclic fatigue resistance as compared to group II and group III.

Conclusions: Within the limitations of this study HyFlex EDM exhibited the greater cyclic fatigue resistance when compared with the other two rotary file systems used in the study.
