Abstract:

The nickel-titanium instrument is more and more used in root canal preparing. Twisted Files（TF） is manufactured by a proprietary twisting process, so it maintains original canal shape, and presents great resistance to cyclic fatigue. In this article, we review these studies about cutting efficiency and maintaining original canal shape, cyclic fatigue of TF, and its effect about autoclaving.

Key words: Twisted Files, nickel-titanium instrument, cyclic fatigue, intracanal fracture
