“…According to the results of the present study, the fatigue life of WOG was found to be shorter than TE, but no statistically significant difference was found when compared to RPC files. Similar to present study results, Özyürek24 has reported the cyclic fatigue resistance of WOG files to be higher than RPC files. However, Topcuoglu et al23 have carried out a study on comparing the number of cycles to the failure of WOG, WO, and RPC files, and reported that the cyclic fatigue resistance of WOG files was higher than other files.…”

ObjectivesTo compare the fatigue life of Tango-Endo, WaveOne GOLD, and Reciproc NiTi instruments under static model via artificial canals with different angles of curvature.Materials and MethodsReciproc R25, WaveOne GOLD Primary, and Tango-Endo instruments were included in this study (n = 20). All the instruments were rotated in artificial canals which were made of stainless steel with an inner diameter of 1.5 mm, 45°, 60°, and 90° angles of curvatures and a radius of curvature of 5 mm until fracture occurred, and the time to fracture was recorded in seconds using a digital chronometer. The data were analyzed using Kruskal-Wallis and post-hoc Dunn tests were used for the statistical analysis of data in SPSS 21.0 software.ResultsTango-Endo files were found to have significantly higher values than WaveOne GOLD and Reciproc files in terms of fatigue life (p < 0.05). However, there was no statistically significant difference between fatigue life of Reciproc and WaveOne GOLD files (p > 0.05). It was determined that increasing the angle of curvature of the stainless canals caused significant decreases in fatigue life of all of three files (p < 0.05).ConclusionsWithin the limitations of the present study, the cyclic fatigue life of Tango-Endo in canals having different angles of curvature was statistically higher than Reciproc and WaveOne GOLD.

“…There was no significant difference in the mean lengths of the fractured fragments of any of the files tested. The fractured length of each file was at the centre of the curvature (approximately at 5 mm from the tip of the instrument) and this confirmed the positioning of the instruments in a precise trajectory (Özyürek ).…”

“…Gold heat treatment is performed manually by heating the instrument and then cooling slowly, contrary to the premanufacturing heat treatment of M‐Wire technology. According to the manufacturer, this new heat treatment enhances the elasticity of the instrument (Webber , Özyürek ). In addition, the greater flexibility of WaveOne Gold instruments could be due to the high A f temperatures and the two‐stage specific transformation behaviour which improves the flexibility property (Özyürek ).…”

“…WaveOne Gold has changed geometry and dimensions compared to WaveOne, and it replaced the original WaveOne product line (Dentsply Tulsa Dental Specialties ). WaveOne Gold is formed by a gold heat‐treatment process after manufacture, contrary to the premanufacturing heat treatment of M‐Wire technology (Özyürek ). This new technology is supposed to improve the strength and flexibility of the WaveOne Gold instruments (Dentsply Tulsa Dental Specialties ).…”
