Background: Apical debris extrusion may be associated with pain and/or swelling in the presence of a severe inflammatory response in clinical practice. The present study was conducted to assess apical extrusion of debris with different files system. Materials & Methods: The present study was conducted on thirty freshly extracted maxillary central incisors. The 30 roots were divided into three groups based on the NiTi system. In group I PTN files were used in the sequence ProTaper Universal SX, PTN X1, PTN X2, PTN X3, PTN X4 and PTN X5. In group II, TF adaptive instruments were used in the sequence ML1, ML2, and ML3. In group III, a Reciproc R25 instrument was used. Results: Debris extrusion in group I was 0.00048 grams, in group II was 0.00059 grams and in group III was 0.00051 grams. The difference was non- significant (P> 0.05). Conclusion: We found that maximum amount of debris were extruded by TF adaptive instruments followed by Reciproc R25 and PTN files system.
Key words: Apical debris, PTN files, Reciproc R25
