“…Therefore, there have been multiple attempts to develop NiTi files that are less likely to transport and more resistant to fracture. Prior attempts have utilized electropolishing (Bui et al, ), ion implantation (dos Santos et al, ), surface coating, and heat treatment (Braga et al, ; Chang et al, ). Recent attempts have used thermal treatments (Shen et al, ) to modify the phase transition temperatures (Gutmann and Gao, ) and thereby enhance the mechanical properties of the files (Gutmann and Gao, ).…”

“…Given the variations in form, length, and anatomy of human root canals, many studies have opted to use extracted human teeth to produce more clinically faithful results [16]. However, despite the benefits of this approach, other studies [5][6][7][8][9][10][11][12] chose to use simulated canals, which allow for a level of standardization that cannot be obtained using extracted human teeth [17]. Moreover, epoxy-resin simulated root canals are similar to human dentin in hardness, enabling extrapolation of the experimental results to clinical practice [18].…”

“…Although the introduction of nickel-titanium (NiTi) instruments seemed to overcome this difficulty [1], the preparation of curved root canals results in morphological alterations, including wear, disappearance of the cutting edge, microfractures, and surface defects, to the instrument surface [2][3][4][5][6][7]. New surface treatment methods, such as ion implantation and plasma nitriding, have been investigated to improve the properties of these instruments and extend their life [8][9][10][11][12].…”
