Introduction: To compare the cyclic fatigue resistance of three rotary glide-path file systems (ProGlider, Px-One, and Pro-path) in simulated canals with double curvature. Materials and Methods: <0.05). Results: canals, Pro-path again demonstrated superior performance (18.90±4.86 min), followed by ProGlider (5.71±1.23 min) and Px-One (4.70±1.20 min). Conclusions: these experimental conditions, Pro-path demonstrated significantly greater cyclic fatigue resistance than ProGlider and Px-One in double-curvature simulated canals. However, the absence of body temperature control and a static testing model limits clinical extrapolation. Further studies validating these findings under physiological conditions and dynamic kinematics are warranted.
