Aim: Comparative evaluation of buckling resistance of Proglider and One-G file, An In vitro Study. Materials and Methods: The test instruments – Proglider and One-G files were subjected to a devised buckling resistance test, which consisted of the application of an increasing load in the axial direction of the instrument by using a universal testing machine. The maximum load required to generate a lateral elastic displacement of 1 mm was recorded for each instrument. Data were analyzed using the one-way ANOVA test. Results: The results indicated that the buckling resistance of One-G files is significantly better than Proglider files (P < 0.05). Conclusion: One-G rotary files manufactured with conventional nickel-titanium alloy showed higher buckling resistance compared to Proglider files manufactured with M-wire alloy.
