| Abstract | ||
| Aims: To evaluate volumetric amount of endodontic obturating materials remnants after endodontic retreatment using two retreatment rotary systems (R-Endo and EdgefileXR)with and without supplementary retreatment(XP-Endo Finisher), in teeth obturated by Sure-Seal Root TM (Bioceramic sealer). Materials and Methods: Twenty human mandibular premolars with single straight root canals were prepared using a 2Shape endodontic rotary system with a file size of 25/0.04. All teeth were obturated using gutta-percha and Sure-Seal Root TM (Bioceramic sealer) using the single cone technique. The samples were then divided into two groups according to the retreatment system used (n=10). After retreating all samples with different rotary systems, the samples were evaluated using CBCT images. CBCT images of each sample were taken and evaluated in axial, coronal and sagittal planes to determine the obturating material remnants after retreatment. Then, all samples retreated with two retreatment systems (R-Endo and EdgefileXR) underwent supplementary retreatment with XP-Endo Finisher. Second CBCT images for each sample were taken and the volume of the remnant material inside the canal walls was analyzed. Data were analyzed statistically using one-way ANOVA analysis of variance, Duncan’s multiple analysis rang test and independent t-test. Results: EdgeFileXR and R-Endo were significantly different and XP-Endo Finisher improved the removal of obturating materials in both groups. Conclusions: The retreatment system had a significant effect on the amount of endodontic obturating material remnants after endodontic retreatment and XP-Endo Finisher had a supplementary removal effect. | ||
