A Comparative Evaluation of Sealing Ability of Three Recent Root-End Filling Materials: An In Vitro Study

Abstract

Aims and Objective: The aim of the study was to evaluate and compare the apical sealing ability of mineral trioxide aggregate (MTA) Plus, Biodentine, and MTA. Materials and Methods: One forty maxillary incisors were obturated with gutta-percha and AH Plus sealer. All samples were randomly divided into 2 control and 3 experimental groups of 28 samples each. In the Group I, no apical preparation was done. The apical 3 mm of the samples in the other groups were resected, and 3 mm deep cavity was prepared and filled with gutta-percha, Biodentine, MTA Plus, and MTA, respectively. In negative control group, the entire specimen was coated with three layers of nail varnish; all samples in Groups II-V were coated with three layers of nail varnish except at the apical resected root surface. All samples were immersed in 2% rhodamine B dye for 72 h. The teeth were then sectioned longitudinally and examined under stereomicroscope. Results: MTA Plus showed less microleakage compared to Biodentine and MTA. Conclusion: MTA Plus showed a better seal than that of Biodentine and MTA.
