Introduction: Sterilization of the root canal is a prime aim successful endodontics. The cleaning and shaping directed as achieving this goal. extrusion apical debris has deleterious effect on prognosis treatment. Several instrument designs instrumentation techniques have been developed to prevent this. Materials Methods: Forty caries free single rooted human mandibular premolar teeth were divided in four groups ten each. Teeth each group instrumented until working length with rotary ProTaper, K3, Mtwo systems, hand K-type stainless steel files. Debris irrigant extruded from foramen collected into vials amounts quantitatively determined. data obtained analyzed using Kruskal-Wallis one-way analysis variance Mann-Whitney U tests. Results: results show that all produced significant amount irrigant. engine-driven nickel-titanium systems showed less than manual technique. No statistically difference was found between at [P > 0.05]. Maximum seen K-file least group. Conclusions: use files perform does apex. This can contribute more endodontic therapy.
