Abstract

Introduction: This study aimed comparatively evaluate the relationship between penetration in simulated lateral canals and apical microleakage of AH Plus Jet, TotalFill BC and GuttaFlow Bioseal root canal sealers. Materials and methods: Thirty single-rooted extracted human mandibular premolars were decoronated and the root canal length was standardized at15mm, simulated lateral canals were made. After chemo-mechanical preparation, the specimens were randomized into three experimental groups according to the root canal sealers: TotalFill BC, AH Plus Jet, and GuttaFlow Bioseal root canal sealers. In all groups, root canal filling was performed with a single cone technique. The specimens were immersed in 2% methylene blue dye solution and then, subjected to the clearing technique. A stereomicroscope was used to observe the specimens. The penetration depth of root canal sealers in simulated lateral canals and apical microleakage were assessed by a four-grade scoring system (0.3). Data were statistically analyzed by Spearman correlation test at 5% significance. Results: Statistically, there was no significant correlation between penetration depth and apical microleakage of AH Plus Jet sealer (P>0.05). Instead, there was a significant correlation between penetration depth and apical microleakage of TotalFill BC sealer at apical simulated lateral canals whereas GuttaFlow Bioseal sealer showed a significant correlation at coronal simulated lateral canals (P<0.05). Conclusions: GuttaFlow Bioseal and TotalFill BC sealers showed an association between their penetration depth and apical microleakage whereas AH Plus Jet sealer showed no association between its penetration depth and apical microleakage.
