Objective: To compare the influence of different clinical operative motions (pecking motion vs. MIMERACI) on apical debris extrusion using WaveOne Gold and EdgeOne Fire reciprocating files in the mesiobuccal canal of extracted molars. Material and Methods: Sixty mandibular molar teeth with curvature less than 20° were divided into 4 groups (n=15 each): G1A: WOG pecking Group; G1B: WOG MIMERACI Group; G2A: EOF pecking Group; and G2B: EOF MIMERACI Group. The produced debris was collected in the preweighed Eppendorf tubes and following the shaping procedures; they dried in the incubator for 5 days at 70o C. The tubes were weighed again, and the final extruded debris was measured by subtracting the pre-instrumentation from post-instrumentation weight of tubes. The canal preparation time was calculated with a digital chronometer. The obtained data were analyzed using two-way ANOVA at a 0.05 level of significance. Results: MIMERACI method significantly decreased the amount of debris pushed out in both instruments (p<0.05). Neither instruments nor clinical motions created a statistical difference regarding the required time (p>0.05). Conclusion: All tested instruments pushed debris out apically at some level, but MIMERACI operative technique was associated with significantly less apical debris extrusion.
