Abstract

Introduction: The quality of root canal treatment depends on the sealing ability of root canal obturation materials. Sealers help create an impenetrable seal. This study aimed to compare the sealing ability of AH Plus and Sure-Seal Root sealers by the fluid filtration technique. Methods: This in-vitro study evaluated 80 extracted human mandibular second premolars. After initial preparation, the teeth were randomly divided into two experimental groups (n=35) and positive and negative control groups (n=5). The experimental groups were obturated with AH Plus sealer and Sure-Seal Root sealer. The AH Plus and the Sure-Seal Root groups were obturated with the lateral condensation technique and the single-cone technique, respectively. Apical leakage was assessed at two intervals of 1 week and 3 months, evaluated by the fluid filtration technique, and compared between the two groups using Student’s t-test. Results: No significant differences were observed between the two groups in 7 days. However, after 90 days, the AH Plus group exhibited significantly less leakage than the Sure-Seal Root group. The microleakage of AH Plus decreased over time (P<0.05). Conclusion: In this study, AH Plus exhibited significantly better sealing ability than Sure-Seal Root in the long term. © 2022, Mashhad University of Medical Sciences. All rights reserved.
