The aim of this study was to evaluate the quantity apically extruded debris after canal shaping with three single-file systems.Sixty mesiobuccal canals mandibular molars were divided into experimental groups according used file systems-WaveOne Gold, RECIPROC Blue, and HyFlex EDM One file. Debris during collected in preweighed vials. Each irrigated 5 mL distilled water via a 30 G side-vented needle. amount from each calculated by subtracting preinstrumentation postinstrumentation measurement. preparation times recorded. Data analyzed using analysis variance (ANOVA) posthoc Tukey tests α = 0.05.WaveOne Gold least debris. Results between WaveOne significantly different. No significant differences time detected among (P > 0.05).WaveOne showed best results regarding apical extrusion. Difference suggests that design motion kinematics affect
