Background: Complete seal at dentin-sealer-core interface of the root canal is required to maintain long-term periapical health. Aim: The aim of this in vitro scanning electron microscopic (SEM) study was to determine which of the commonly used root canal sealer among AH-Plus, GuttaFlow, and RealSeal provides a superior marginal adaptation with the dentin in the apical third region of root canals. Materials and Methods: Selected 30 human freshly extracted maxillary central incisors were biomechanically prepared, then divided equally into three groups and obturated with AH-Plus, GuttaFlow, and RealSeal using single-cone obturation technique. After sectioning longitudinally, apical third of the roots was observed under SEM; dentin-sealer-core interface was focused. Marginal adaptation and interfacial gaps at dentin-sealer interface of all the samples were evaluated and analyzed statistically in this part of the article. Statistical Analysis Used: Analysis of variance and post hoc Tukey's test. Results: GuttaFlow exhibited least average marginal gap of 2.38 ± 1.43 μm, followed by AH-Plus (4.11 ± 2.85 μm) and RealSeal (4.65 ± 3.91 μm) with no significant difference (P > 0.05) among the groups. Conclusions: As the dentin-sealer interfacial gap is seen to be minimum in GuttaFlow, it is better adapted to dentin in the apical third of root canals compared to AH-Plus and RealSeal.
