A Study Comparing The Retreatment Efficacy Of Calcium Hydroxide-based Root Canal Sealers
Aylin KalaycI*, Berna Aslan**, Lale Zaİmoğlu***
Purpose: The purpose of this study was to evaluate the efficacy of ultrasonic retreatment after obturation with either Apexit, CRCS, or Sealapex and gutta-percha.
Material and Method: Sixty freshly extracted, single-rooted teeth were obturated with three different calcium hydroxide-based root canal sealers and stored in 100% humidity for 2 months. All of the root canals were then retreated.After retreatment vertical grooves were cut along the buccal and lingual sides of the roots. Both halves of the split roots were viewed in a stereomicroscope at X2.5 magnification.Data were evaluated statistically.
Results: The differences in debris scores at each level within each sealer group and among the groups were statistically analyzed using Friedman test , Kruskal-Wallis test all with 5% level of significance. The amount of debris was the highest in roots obturated in conjunction with CRCS and lowest in control group at each canal level(p < 0.05).Differences among the groups in retreatment time were compared using analysis of variance.The mean time required for retreatment was the longest in canals obturated in conjunction with Sealapex, followed by CRCS and Apexit.These differences were statistically significant (p < 0.01).
Conclusion: The results of this study showed that amount of debris remaining on the root canal walls following retreatment was the lowest, and the mean time required for retreatment was the shortest in control group.Among the root canal sealers used in this study, amount of debris remaining on the root canal walls following retreatment was the lowest in Apexit group. Furthermore,the mean time required for retreatment was the shortest in Apexit group.Keywords: Calcium hydroxide-based root canal sealers, RetretreatmentTurkiye Klinikleri J Dental Sci 1997, 3:84-88
