| Abstract | ||
| Aims: This study was aimed to measure the quantity of residual material remained in root canals after root canal system being retreated by rotary instruments of three types:EdgefileXR, D-RaCe, and R-Endo in teeth that their canals filled by either single cone method or the continuous wave compaction method. Methods: human mandibular cuspid teeth (n=60) had only one non curve canal were instrumented with file (25/0.04). Then, the teeth classified into two main groups depending on the technique that they were obturated with (thirty teeth for each group): A: single cone method and B: continuous wave compaction method. After that, other subcategories, for each of the groups subdivided into three subgroups depending on the retreatment system that used(n=10/group) as following: A1, B1: D-RaCe, A2, B2: REndo, and A3, B3: EdgefileXR. The teeth were analyzed by using cone beam, computed tomography with aid of AutoCAD software to evaluate the percentage of residual obturating material. We used both tests one, way ANOVA;and post hoc, Duncan to analyze the data statically. Results:the results were found there was significant; difference between D-race and other two rotary systems, while no significant difference between EdgefileXR and R-Endo in both technique of obturation. Also, this study reported there was no difference statically in the same rotary system in both0 techniques of obturation. Conclusions: All rotary retreatment systems left residual obturating material. EdgeFileXRl rotary system is more effective, among systems. | ||
