Debris extrusion, is among the difficulties experienced on instrumentation that accompanied by postoperative discomfort. This research was escorted to judge the effectiveness of XP Endo Shaper,iRace and Protaper Next rotational systems considering the extruded debris. Materials &Methods: Forty-five single-rooted human mandibular premolars extracted teeth with closed apex. Selection of teeth with curvatures (0°–10°). Buccolingual and mesiodistal instructions were followed to substantiate just one canal as clarified by digital radiograph. Teeth had been sorted randomly into 3 groups of 15 teeth individually using NiTi rotational system for root canal preparation, ensuring glide path and equal representation of all ranges of curvature. Group A: XP rotating system. Group B: Protaper Next rotating system Group C: iRace rotating system. A variation of Myers and Montgomery's equipment as previously proposed in respect of the quantitative assessment of apical debris expelled. Using Eppendorf tubes at a microbalance with four decimal places in grams before and after the instrumentation. The sum of three consecutive weights was computed after five times for weighing every tube. As regard to weight estimation, subtraction had been done for tube's starting weight from its final weight. Results: Significantly, PTN group has the greatest mean value afterwards the iRace and the tiniest value has been recorded for the XPS (p<0.05). While the XPS and iRace groups (p>0.05) reported no remarkable difference. Conclusions: The mass of apically expelled debris was PTN > iRace > XPS with a statistical difference. XPS as single file extrude minimal mass of debris.
