Objective: The study aims to compare the cyclic fatigue resistance of the WaveOne Gold Glider and TruNatomy Glider files within artificial double-curvature canals.
Methods: The study includes 12 pieces WaveOne Gold Glider (15.02v) and 12 pieces TruNatomy Glider (17.02v) nickel-titanium files which were used according to the the manufacturer's instructions until they were broken in artificial double-curvature canals. The artificial double-curvature canals which were used in the study were made of stainless steel. The fracture time was recorded using a digital stopwatch. The rotation number until fracture was also calculated. Moreover, the lengths of the broken pieces were recorded. Data were statistically analyzed using an independent sample t-test.
Results: The number of rotations until fracture for the WaveOne Gold Glider file was found higher when compared to TruNatomy glider file. Statistically significant difference was found between two groups. (p<0.05) There was no statistically significant difference between the groups in terms of the lengths of the fragments.
Conclusion: In our study, the resistance of the WaveOne Gold Glider Nickel- Titanium(Ni-Ti) file to cyclic fatigue in double curved canals found to be higher than that of the TruNatomy Glider Ni-Ti file.
