Drs. Peet J. van der Vyver and Michael J. Scianamblo discuss the clinical guidelines for using Protaper Next instruments

According to Bird, Chambers, and Peters (2009), rotary nickel-titanium (NiTi) instruments have become a standard tool for shaping root canal systems. These instruments provide the clinician with several advantages compared to conventional stainless steel instruments.

They are more flexible, have increased cutting efficiency (Kim, et al., 2012; Peters, 2004; Walia, Brantley, Gerstein, 1988), can create centered preparations more rapidly (Short, Morgan, Baumgartner, 1997; Glossen, et al., 1995), and can produce tapered root canal preparations with a reduced tendency of canal transportation (Chen, Messer, 2002; Kim, et al., 2012). 

However, nickel-titanium instruments appear to have a high risk of fracture (Arens, et al., 2003; Sattapan, et al....
