Introduction: A glide path preparation prevents the fracture of endodontic files and maintains a centered root canal configuration. This study aimed to evaluate and compare the amount of apically extruded debris following the use of various glide path files in severely curved root canals. Materials and methods: Of the 112 extracted human mandibular molar teeth collected, 40 teeth with severely curved mesial roots were selected. The mesial roots of the teeth were sheared off at the cementoenamel junction and pre-weighed Eppendorf tubes were attached to the roots. The specimens were randomly divided into four experimental groups according to canal preparation (n = 10): Group I- HyFlex GPF glide path files; group II- Rotary pathfile; group III- Manual K File glide path; group IV– No glide path preparation. HyFlex CM rotary file system was used to complete the biomechanical preparation of all the specimens up to size 25/06. using 8 mL of distilled water as an irrigant. Eppendorf tubes were then stored in an incubator to calculate the weight of extruded debris, after evaporation. Data comparison was done by applying ANOVA followed by post hoc Tukey's test (p < 0.05). Results: There was no statistically significant difference between the rotary glide path groups, but there was a significant difference between debris extruded using rotary glide path file groups as compared to the manual glide path and without glide path file groups. Conclusion: Rotary glide path files caused less debris extrusion than glide path preparation with manual K-files and without glide path preparation in severely curved canals.
