The surface of the fractured instruments was examined under scanning electron microscopy (SEM) at \u00d7250 magnification. The results were compared statistically with one-way ANOVA and post hoc Tukey tests and the alpha-type error was set at 5%.Results: X1 blue file and ProDesign Rinstruments showed highest time to fracture than Reciproc Blue and Wave One Gold (P0.05).
