Abstract: Nickel-titanium root canal instrument is a kind of root canal instrument processed by special nickel-titanium alloy. It is widely used in clinical root canal preparation due to its excellent flexibility, root canal forming ability and advantages of saving time and labor.In clinical use, nickel-titanium root canal instruments are typically sterilized using autoclaving when reused. In recent years, the influence of autoclave sterilization on physical properties of nickel-titanium root canal instruments has attracted much attention. In this paper, the research progress on the surface topology, fatigue resistance, cutting efficiency and autoclave sterilization and thermoelasticity of nickel-titanium rotary instruments is reviewed in order to provide reference for clinical use.

Key words: autoclave sterilization, nickel-titanium root canal instruments, reuse
