A critical analysis of research methods and experimental models to study the physical properties of NiTi instruments and their fracture characteristics

International Endodontic Journal, Volume 55, Issue S1, Page 72-94, March 2022., 2022
Abstract The aim of this review is to provide a critical overview of the physical properties (surface hardness, cutting efficiency, bending properties, flexibility and cyclic fatigue resistance) of NiTi instruments. Frequently used experimental models regarding these aspects will be presented and discussed with regard to their strengths and weaknesses.
