The purpose of this study is to understand how different NiTi alloys condition the flexibility of endodontic instruments at body temperature (37 °C). The alloys are compared in terms of their transformation characteristics by X-Ray Diffraction (XRD) and Differential Scanning Calorimetry (DSC). Two different rotary instruments, a Profile GT®(GT) and a GT® Series X™ (GTX), were selected. GTX files are made from M-Wire, a Ni-Ti alloy allegedly having a higher flexibility at body temperature.
