Abstract: ProTaper is one of the widest used nickel-titanium instruments. However, because of stiffness and high broken rate, its application in clinical has been limited. Recently, Dentsply has pushed out two different NITIs, i.e. WaveOne and ProTaperNext, which aims to reduce the high broken rate. This review summarizes the design features, mechanical properties, and shaping ability of curved canals.
