| Abstract | ||
| The aim of this study was to evaluate the quantitative amount of apically extruded debris after endodontic retreatment using three retreatment rotary systems D-RaCe, R-Endo, and EdgefileXR in the teeth obturated by two techniques (single cone and continuous wave compaction). Sixty human mandibular premolars with single straight root canals were prepared by 2Shape endodontic rotary system with file size (25/0.04). After that, samples were divided into two groups according to the technique of obturation used (n=30/group):A: single cone and B: continuous wave compaction. Then,further random subdivision for each group into three sub groups according to the system used for retreatment(n=10/group) as follow: A1,B1:D-RaCe, A2,B2:R-Endo, andA3,B3: EdgefileXR. Preweighed Eppendorf tubes were used to collect the apical extruded material during endodontic retreatment. Then, Eppendorf tubes were stored in an incubator at 68C for 5 days. The weight of extruded debris was calculated by subtracting the weight of the empty tube from the weight of the tube containing the extruded debris.Data were analyzed statistically using one way ANOVA analysis of variance and post hoc Duncan test. EdgeFileXR and R-Endo were significantly not different, but significantly different from D-race in two obturation technique. Also, result showed that the same system exhibited no difference in both obturation techniques. All retreatment techniques resulted in apical extrusion debris. Also, it was concluded that the techniques of obturation had no significant effect in the amount of apical extruded debris by different retreatment systems used in this study. | ||
