Abstract: Aim: The aim of our study was to determine the cyclic fatigue resistances of four different glide path files namely ProGlider, Hyflex EDM glide path file, NT Rainbow glide path file, NeoEndo Flex Glide in s shaped canals. Materials and Methods: Ten files from each group were tested. An artificial groove simulating s shape was machined in a stainless steel block. The groove measured 1.6mm in diameter at the top and decreasing towards the apical region having 0.4mm at the tip with 0.06 taper, 19 mm in length, and 1.5 in depth was used in this study. Cyclic fatigue resistance was determined by counting the number of cycles to fracture[NCF]. Results: Hyflex EDM glide path files showed significantly higher NCF values when compared to the other glide path files tested. Conclusion: Within the limitations of our study, Hyflex EDM has the highest cyclic fatigue resistance among the glide path files tested.
