Objectives: The purpose of this study was to compare the sealing ability of Biodentine, Mineral Trioxide Aggregate (MTA) and Glass Ionomer Cement (GIC) when used over gutta-percha as intracanal sealing materials. The study also evaluated the sealing ability of Zinc oxide eugenol (ZOE) sealer and AH PLUS sealer. Materials and Methods: Ninety mandibular premolars were prepared using step-back technique and divided into experimental groups A, B (45 premolars each). Teeth were obturated with gutta-percha using sealer ZOE (group A) and AH PLUS (group B). The groups were further divided into 3 subgroups (15 premolars each) on the basis of intracanal sealing material used: GIC subgroups (A1, B1) MTA subgroups (A2, B2) and biodentine subgroups (A3, B3). The clearing technique was used in this study for leakage evaluation. Coronal microleakage was determined under stereomicroscope using 15X magnification. Data was statistically analyzed using one-way ANOVA followed by Post-Hoc Multiple comparison (Bonferroni). Results: Biodentine group leaked significantly less than GIC group (P < 0.05). AH Plus sealer exhibited better sealing ability than ZOE sealer. Conclusions: Biodentine or MTA may be preferred over GIC as an intracanal barrier.
Keywords: AH Plus sealer; Biodentine; GIC; Intracanal barrier; Intracanal sealing; MTA.
