It was observed that most of the files showed defects that appeared as lengthening of the spirals due to the unwinding without fractures.

Particularly in root canals with abrupt hylex this can help avoid the creation of steps. A major innovation in endodontics has been the introduction of nickel-titanium NiTi alloy to manufacture root canal instruments, mainly due to the superelasticity of the NiTi alloy, which provides increased flexibility and allows the instruments to effectively follow the original path of the root canal.

Only 4 files showed slight defects at the tips of the files.

Fatigue resistance of engine-driven rotary nickel-titanium instruments produced by new manufacturing methods. Defects in nickel-titanium instruments after clinical use. Three-dimensional analysis of root canal geometry by high-resolution computed tomography.

The defects for each file after use and after autoclaving were recorded. Irrigation with distilled water was performed frequently when using the files. Articles from Journal of International Oral Health: Canal shapes analysed by micro-computed tomography. These changes were categorized according to the severity, and the initial and final scans of the files were superimposed to illustrate the recovery of the files to their original shape.

Before the initial scans were performed, a customized jig was fabricated, and each file was mounted such that it could be placed in the same position before and after use. Furthermore, many studies showed the new CM-wire manufacturing process fils produce NiTi rotary instruments that were more flexible and more resistant to cyclic fatigue than instruments produced by a traditional manufacturing process or a thermally treated NiTi alloy M-wire.

Torsion and bending properties of shape memory and superelastic nickel-titanium rotary instruments. Discussion At the beginning ofa series of studies 12 – 15 found that changes in the transformation behavior via heat treatment were effective in increasing the flexibility of NiTi endodontic instruments.

The explanation for this phenomenon may be that heating transforms the metal temporarily into the austenitic phase, which makes it possible for the file to regain its original c, before cooling down again. Follow Dental Directory on: Therefore, with the limitations of this study, it can be concluded that the shape of files with unwound spirals can be restored during autoclaving.

This form adaptation can be reversed quickly by heat treatment during autoclaving or with a glass bead sterilizer returning the instruments back to their original shape. Introduction A major innovation in endodontics has been the introduction of nickel-titanium NiTi alloy to manufacture root canal instruments, mainly due to the superelasticity of nuti NiTi alloy, which provides increased flexibility and allows the instruments to effectively follow the original path of the root canal.
