BACKGROUND Extrusion of debris, bacteria, and irrigant effect the inter-appointment flare ups and post-operative outcome of the endodontic treatment. So, it is necessary to make every effort to minimize such extrusion during cleaning and shaping of the canals. The present study was done to compare and evaluate debris and irrigant extrusion from curved root canals using different Ni-Ti systems. METHODS 30 mesial roots of mandibular molars were used in this study. Crown were decoronated, working length and initial apical diameter was established. 1.5 % agar gel model was used in this study. Samples were assigned randomly into 3 groups (n = 10 teeth per group). ProTaper Next, One Shape, FANTA AF BLUE F ONE files were used according to the manufacturer’s instructions for canal instrumentation. Apically extruded debris and irrigant was computed after the biomechanical preparation and their comparative analysis for each of the instruments and experimental models was performed. RESULTS Statistically significant difference was found between the three experimental groups. (P < .05). CONCLUSIONS All the instruments produced apically extruded debris and irrigant, but least was seen with FANTA AF BLUE F ONE and maximum with One Shape among the experimental groups. KEY WORDS Apical Debris, Irrigant, NiTi Files
