“…Sterilization with dry heat (11 cycles) is able to produce a significant increment of the superficial roughness in nickel-titanium instruments, leading to an improve of the debris retention capability (17). Other authors have shown that wet heat (with 10 cycles as in our study), produced nanostructural superficial changes in nickel-titanium endodontic files (18). In our work only two instruments experiment fracture.…”

“…Some authors have used a mathematical finite element model (Kim et al, 2009;Necchi et al, 2008) or AFM (Inan et al, 2007b;Topuz et al, 2008;Valois et al, 2005Valois et al, , 2008.…”

“…AFM has been used in Endodontics to provide qualitative and quantitative information about the topography of a large variety of metal materials (Inan et al, 2007a;Topuz et al, 2008;Valois et al, 2005Valois et al, , 2008.…”

“…Serene et al (12) have suggested that NiTi deformation caused during clinical use could possibly be reversed by using sterilization temperatures above 125 C. Although no effect of autoclave sterilization on Lightspeed NiTi rotary instruments (Discus Dental, Culver City, CA) has been reported; Profile NiTi rotary files have shown a higher mean cycle to failure when exposed to both dry heat and autoclave sterilization (13,14). Similar reports of autoclave conditions either improving or degrading both the performance and physical properties of various marketed rotary NiTi systems have been noted (14)(15)(16)(17)(18)(19). The purpose of this study was to investigate the effect of repeated autoclave cycles on the cyclic fatigue resistance of Twisted Files and GT Series X files.…”
