Introduction: The aim of nonsurgical retreatment is to remove the previous filling material followed by chemo-mechanical preparation of the canal to achieve proper disinfection of the root canal system. This is then followed by re-obturation. This study evaluates the time taken to retrieve the gutta-percha and the quantity of remaining filling material after retreatment with two different file systems. The quantity of remaining filling material was assessed using nano-computed tomography (CT) due to its increased accuracy. Materials and Methods: Forty extracted single-rooted teeth were split into two groups at random and decoronated and obturated at a standard root length of 16 mm. Solite RS3 (SRS-3) Retreatment and ProTaper Universal Retreatment (PTUR) systems were used to retrieve the gutta-percha after a preoperative nano-CT scan. Postoperative nano-CT scan was taken and both the scans were superimposed to quantify the remaining filling material. The time taken to remove gutta-percha was measured using a stopwatch. The statistical analysis comparing the two groups was conducted using the independent t-test. Results: The quantitative analysis of remaining filling material using nano-CT showed no statistical difference between both the file systems used (P > 0.05). However, SRS-3 took significantly less time in the removal of gutta-percha (P < 0.05). Conclusion: Hence, we can conclude that there is no significant difference in the amount of remaining filling material between both the file systems. However, time taken to remove the gutta-percha was lesser in SRS-3 compared to PTUR file system.

“…Because of the complexity of the apical area of the root canal (intracanal isthmuses, constriction, and apical delta), which was observed in the majority of cases, the results of this study revealed that two rotary retreatment systems (R-Endo and EdgefileXR) left filling materials in the canal after retreatment for canals previously obturated by epoxy resin sealer (T-Seal) (30) . The current study found that the EdgefileXR retreatment system for T-Seal sealer was more effective than the R-Endo retreatment system in removing obturating materials.…”

Aims:To evaluate the volumetric amount of endodontic obturating materials remains after endodontic retreatment with and without complementary retreatment(XP-Endo Finisher) utilizing two retreatment rotary systems (R-Endo and EdgefileXR).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. Gutta-percha and T-Seal (Epoxy resin sealer) were used to obtain all the teeth using a single cone technique. Samples were then divided into two groups based on the retreatment system used (n=10). CBCT images of each sample were taken and analyzed in axial, coronal, and sagittal planes to determine the obturating material remnants after retreatment. Then, all samples retreated by two retreatment systems (R-Endo and EdgefileXR) were subjected to supplementary retreatment by the XP-Endo Finisher. Second CBCT evaluation were performed to determine the XP-Endp Finisher effect. The data were statistically analyzed using one-way ANOVA analysis of variance, independent t-test, and Duncan's multiple analysis rang test. Results: EdgeFileXR and R-Endo were significantly different, EdgefileXR is more effective and XP-Endo Finisher improved removal of obturating materials in both groups. Conclusions: The retreatment system had a significant effect on the amount of endodontic obturating materials remnants, XP-Endo Finisher show a supplementary removal effect.
