Thermal behavior and cyclic fatigue resistance of three contemporary NiTi heat-treated single-file systems: metallurgical study.

ABSTRACT:

Background

This study aims to determine phase transformation temperatures of EndoSequence Reciprocating System (ESR), Wave One Gold (WOG), and Reciproc Blue (RB) via differential scanning calorimetry (DSC). Further, to evaluate the cyclic fatigue behaviors by applying static (SF) and dynamic fatigue (DF) tests.

Methods

All files' systems were evaluated using DSC (Netzch 200 F3, Germany) with scans ranging from 80°C to -80°C to compare phase transformation. Twenty files from each file system (n = 20) were tested by cyclic fatigue in SF (n = 10) and in DF (n = 10) and the number of cycles to failure (NCF) was calculated for all groups. The files were rotated in a clockwise motion in a metal tube at 350rpm. The NCF was calculated by multiplying the time until fracture in minute
