The produced debris was collected in the preweighed Eppendorf tubes and following the shaping procedures; they dried in the incubator for 5 days at 70<sup>o</sup> 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. <strong>Results:</strong> MIMERACI method significantly decreased the amount of debris pushed out in both instruments (p&lt;0.05). Neither instruments nor clinical motions created a statistical difference regarding the required time (p&gt;0.05). <strong>Conclusion:</strong> All tested instruments pushed debris out apically at some level, but MIMERACI operative technique was associated with significantly less apical debris extrusion.</p> ER -
