NiTi plays a major role in the advancement in this specialty, which promotes the quality of the endodontic treatment. With the invention of NiTi, various modifications in the design and flexibility of the endodontic instruments were improved by the surface treatment and thermal treatments. In addition to the advancements in the field of dentistry newer movements of the instruments were incorporated offering greater safety and efficiency during root canal treatment. A better understanding of the mechanical properties of these new NiTi instruments and the efficacy of the instruments on the clinical performance is essential if dental practitioners are to select the instruments that provide optimal clinical outcomes, especially in curved or flattened canals. The objective of this literature review is to discuss the characteristics of the NiTi alloys used in the manufacturing of the endodontic instruments as well as an overall view on the metallurgical and mechanical properties of NiTi instruments used in dentistry.
