An Ex-vivo Evaluation of Sealability of Three Bioceramic Physical Variants in Coronal and Apical Thirds of Root Canals.

Abstract

Aim: To assess the coronal and apical microleakage of mineral trioxide aggregate (MTA), Biodentine, and Bioceramic putty when used as coronal and apical seals in endodontically treated teeth.

Materials and methods: The study was conducted on 90 mandibular premolar teeth. The groups were divided into two subgroups. One group assessed the coronal seal (n = 45), and the other group assessed the apical seal (n = 45). Coronal and apical 3 mm of the root filling was removed and replaced randomly with MTA, Biodentine, and Bioceramic putty in the three experimental subgroups (n = 15). All teeth were immersed in methylene blue and after incubation, the degree of dye penetration was assessed under a stereomicroscope of ×10 magnification. Statistical analysis was done using the Kruskal-Wallis test with a p-value set at 0.05.

Results: The mean depth of dye penetration for coronal sealing in the MTA group was 2.91 ± 0.66, in the Biodentine group was 2.12 ± 0.50 and in the Bioceramic putty group was 1.51 ± 0.46. The mean depth of dye penetration for root-end sealing in the MTA group was 0.75 ± 0.55, in the Biodentine group was 1.94 ± 0.88 and in the Bioceramic putty group was 0.29 ± 0.20.

Conclusion: Within the limitations of this study, it can be concluded that Bioceramic putty exhibited better sealing ability in both coronal and apical barriers of root canals.

Clinical significance: The sealing ability of a material vastly influences the treatment outcome of nonsurgical and surgical root therapy. The study evaluates the coronal and apical seal of three physical variants of Bioceramic material. How to cite this article: Rao MH, Krishnan R, Gopal P, et al.
