Background: As we all know that apical extrusion of debris also referred to as a “worm of necrotic debris,” is an unfavorable incident that occurs during the instrumentation of the root canal system. Also, one of the main reasons for the failure of root canal treatment is the apical extrusion of pulp tissue, microorganisms, and irrigants beyond the apical foramen. 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: This study was performed on thirty freshly extracted maxillary central incisors. In all the selected samples, 30 roots were further segregated into three groups based on the NiTi system. Accordingly, in group I PTN files were used in the sequence ProTaper Universal SX, ProTaper Next system X1, ProTaper Next system X2, ProTaper Next system X3, ProTaper Next system X4 and ProTaper Next system X5. In group II, TF (Twisted File Adaptive) adaptive instruments were used in the sequence ML1, ML2, and ML3. In group III, Reciproc R25 instrument was used. Results: Statistical analysis was done using statistical software ‘Statistical Package for the Social Sciences (SPSS)’. The recorded data was subjected to suitable statistical tests to obtain p values and mean. P ≤ 0.05 was considered as statistically significant. Debris extrusion in group I was 0.00047 grams, in group II was 0.00058 grams and in group III was 0.00050 grams. The difference was non- significant (P> 0.05). Conclusion: Within the limitations of the study the authors have concluded that maximum amount of debris were extruded by TF adaptive instruments followed by Reciproc R25 and PTN files system. However, we expect other studies to be conducted those include larger samples and wider testing parameters.
