| Abstract | ||
| Aim: Thorough removal of root canal filling materials is essential for achieving successful endodontic retreatment. This study evaluated the canal centering and apical transportation using Solite RE Black and Hyflex Remover retreatment file system during retreatment employing Nano-CT for detailed analysis. Materials and Methods: Thirty extracted human mandibular molars were chosen, and the mesial roots were sectioned to a length of 16 mm followed by instrumentation with the ProTaper Gold system up to size F2, then obturated using the matched taper cone with AH Plus sealer. Teeth were randomly assigned to two groups (n=15 each) for retreatment: Group 1 using Solite RE Black files and Group 2 using Coltene Hyflex Remover files. Nano-CT scans were taken before and after retreatment to assess canal centering at 3 mm, 6 mm, and 9 mm from the apex and apical transportation at 1 mm, 2 mm, and 3 mm from the apex in mesio-buccal and mesio-lingual canals. Data was analyzed using SPSS Software. Results: Nano-CT analysis revealed Solite RE Black system demonstrated superior canal centering ability with less apical transportation compared to the Hyflex Remover system at all levels respectively in both the mesiobuccal and mesiolingual canals (p<0.05). Conclusion: In conclusion, the Solite RE Black system provides better canal centering and reduced apical transportation in the mesiobuccal and mesiolingual canals compared to the Hyflex Remover system during retreatment procedures. Nano-CT proved to be an effective tool for detailed analysis of endodontic retreatment outcomes. | ||
