Özet

Aim: This study aims to provide information about the mechanical characteristics of the files by comparing the torsional, bending and torsion strengths of glide path files with different properties. Method: WaveOne Gold (WOG)(15/v), ROTATE (15/.04), TruNatomy (17/.02), and Scope (17/.03) glide path files were used in this study. Torsional, bending, and buckling strength tests were performed using standard test methods according to ISO 3630-1 specifications (n = 12 from each group for each test). One-way analysis of variance was used to compare normally distributed data, and multiple comparisons were examined with Tukey’s honestly significant difference (HSD) and Tamhane’s T2 tests. The significance level was p < 0.050. Results: No statistically significant difference was found between the torsional strengths. The highest angular deviation value occurred in TruNatomy, while Scope had the highest bending and buckling strengths. Conclusion: The glide path instruments tested had different behaviours on bending, buckling and torsional resistance. Production methods and design features affect the mechanical properties of glide path files. For clinical use, the glide path file should be selected on a case-by-case basis.
