Abstract
ABSTRACT Objective: The purpose of this in vitro investigation was to assess the effectiveness of various gutta-percha retrieval methods in endodontic retreatment. Methods: Five groups were randomly allocated to extract human teeth that had already had root canal therapy: manual files, rotary tools, heat, solvents, and ultrasonics. By evaluating the amount of filling material still present, gutta-percha clearance was quantitatively examined, and root canal cleanliness was qualitatively appraised. To compare the effectiveness of retrieval approaches, statistical analysis was done. Findings: Hand files, heat, and solvents were less effective than rotary devices and ultrasonics at removing gutta-percha (P < 0.05). A quantitative investigation showed that the groups using rotary instruments (0.87 mm) and ultrasonics (0.68 mm) had much less gutta-percha left. The qualitative evaluation revealed that rotary instruments (2.12) and ultrasonics (2.45) had greater cleaning ratings compared to other methods. Conclusion: In conclusion, gutta-percha can be effectively removed during endodontic retreatment by using rotary tools and ultrasonics, which provide both quantitative efficiency and qualitative purity. The implementation of sophisticated retrieval procedures to maximize treatment results in clinical practice is supported by these findings.
