ABSTRACT:-
Background: The sealing ability of root canal fillings is crucial for the success of endodontic treatment. Various obturation techniques have been introduced to enhance this sealing ability, but their comparative impact remains to be thoroughly evaluated. Materials and Methods: In this clinical study, 80 patients requiring root canal treatment were randomly assigned to four groups (n=20 each) based on the obturation technique employed: lateral compaction, vertical compaction, single cone, and thermoplasticized gutta-percha. After obturation, the sealing ability of the root canal fillings was assessed using dye penetration tests and digital radiography. Statistical analysis was performed using ANOVA and post-hoc Tukey tests (p0.05). Results: The mean dye penetration depth and percentage of voids were found to be significantly different among the four groups. The lateral compaction technique exhibited the least dye penetration depth (mean ± SD: 0.15 ± 0.03 mm) and the lowest percentage of voids (6.5 ± 1.2%). Conversely, the single cone technique showed the highest dye penetration depth (0.28 ± 0.05 mm) and the highest percentage of voids (15.2 ± 2.4%). Conclusion: Among the obturation techniques evaluated, lateral compaction demonstrated superior sealing ability with minimal void formation, while the single cone technique exhibited comparatively poorer sealing and increased void presence. These findings underscore the importance of selecting appropriate obturation techniques to optimize the sealing ability of root canal fillings.
