An ideal dental repair material should possess certain exclusive properties such as adequate adhesive ability, dimensional stability, biocompatibility, bioactivity etc. Calcium silicate based materials seem to have intrinsic properties suitable for their clinical use, such as good sealing correlated to expansion, and the ability to set in the presence of fluids, bioactivity, the release of ions acting as epigenetic signals, and good biological properties. The introduction of MTA was considered as a major break-through in the history of material science. Biodentine has been recently introduced as the “the first all-in-one, bioactive and biocompatible material for damaged dentin replacement”. This article attempts to compare the properties and clinical applications of MTA and Biodentine.

This case report describes the management of a supragingivally complicated crown fracture of a maxillary central incisors. The patient aged 12 years gave a history of trauma one year back and got the root canal treatment done. The patient gave a history of not getting the treatment completed after the obturations were done and that led to furthur loss of unsupported tooth structure. In this case fibre post was used in 11. The tooth structure of 21 could not be supported by fiber post so crown lengthening followed by cast metal post and core was given. The teeth were further restored with porcelain fused metal crowns.

An immature tooth with pulpal necrosis and periapical pathology imposes a great difficulty to the endodontist. Endodontic treatment options for such teeth consist of conventional apexification procedure with and without apical barriers. Biodentine is new calcium silicate based cement that exhibits physical and chemical properties similar to those described for certain Portland cement derivatives. This article demonstrates the use of the newer material, Biodentine as an apical matrix barrier in root end apexification procedure. This case report presents apexification and successful healing with the use of Biodentine as an apical barrier matrix.
