Abstract :Purpose: The aim of this study was to evaluate the amount of apically extruded debris during endodontic retreatment with different file systems. Materials and Methods: Sixty extracted human mandibular premolar teeth were used in this study. Root canals of the teeth were instrumented and filled before being randomly assigned to three groups. Guttapercha was removed using the Reciproc system, the Twisted File system insert ignore into journalissuearticles values(TF);, and Hedström-files insert ignore into journalissuearticles values(H-file);. Apically extruded debris was collected and dried in pre-weighed Eppendorf tubes. The amount of extruded debris was assessed with an electronic balance. Data were statistically analyzed using one-way ANOVA, Kruskal-Wallis, and Mann-Whitney U tests. Results: The Reciproc and TF systems extruded significantly less debris than the H-file insert ignore into journalissuearticles values(p<0.05);. However, no significant difference was found between the Reciproc and TF systems. Conclusion: All tested file systems caused apical extrusion of debris. Both the rotary file insert ignore into journalissuearticles values(TF); and the reciprocating single-file insert ignore into journalissuearticles values(Reciproc); systems were associated with less apical extrusion compared with the H-file.
