The History, Evolution and Metallurgical Innovations in NiTi Endodontic Rotary File System

Dr. Akash Azad | Dr. Shraddha Chokshi


Abstract: The quality of cleaning and shaping root canals has significantly improved thanks to nickel - titanium (NiTi) rotary instruments. These instruments' super elasticity and shape memory lessen the possibility of canal transportation while also saving time for patients and medical professionals. The cross - sectional shapes, cutting edges, taper, number, and spacing of the flutes of these instruments, as well as the properties of the NiTi alloy, have all been altered to create a variety of commercial types of these instruments that are currently on the market. The objective of this literature review is to present and discuss the latest innovations of the NiTi alloys used in the major instrumentation systems available in the market, as well as the historical journey through which the Endodontic NiTi Rotary systems have formed and the Evolution of file system, to enable clinician better understand the correct selection of the rotary file for predictable planning of root canal preparation.
