Over the past three decades, the nickel–titanium (NiTi) rotary instruments have highly improved the quality of the cleaning and shaping of the root canals. Their unique super-elasticity and shape memory of these instruments reduce the possibility of the canal transportation along with saving the time for both the patients and the clinicians. Several commercial types of these instruments, produced by different manufacturers, have currently become available by modifying the characteristics of NiTi alloy and also the cross-sectional shapes, cutting edges, taper, numbers and distances between the flutes of the instruments. Five generations for NiTi rotary instruments have been introduced based on the properties, and method of application, till date with numerous advancements in their newer alloy microstructure with various surface treatments to improve its mechanical properties.
