Abstract

Objective This study aimed to evaluate adaptation of mineral trioxide aggregate (MTA), Biodentine, and MTA Plus when used as root-end restorative materials using scanning electron microscope. Materials and Methods Forty-five extracted teeth with one root canal were cleaned and sectioned at cementoenamel junction, maintaining a standardized length of 15 mm. Chemomechanical preparation and obturation was done in all the samples, and access was restored with glass ionomer cement (GIC). Root-end cavities were prepared in all the samples after 3-mm apical root end was resected. Forty-five samples were divided into three groups with 15 samples each. Root apices were filled with ProRoot MTA in group I, Biodentine in group II, and MTA Plus in group III. The sample teeth were sectioned for examination of gaps at the margins using scanning electron microscope. The data collected were put to statistical analysis by one-way ANOVA (analysis of variance) and post hoc tests. Results The minimum margin gap score of 2.44 μm was observed in group II (Biodentine), whereas maximum gap score of 5.63 μm was observed in group I (ProRoot MTA); 4.92 μm mean margin gap score was observed in group III (MTA Plus). Conclusion Biodentine showed least margin gap at the interface, so it can be considered as the best root-end filling material, whereas, MTA Plus can be considered as a substitute to ProRoot MTA as a root-end filling material.
