Perforations are anomalous communications between the root canal system and the external dental surface that connects the pulp cavity to the periodontal tissue. Current advances in biomaterials has made the recovery of tooth structure and function possible even in the most complicated cases. Ideally, perforations should be immediately repaired with a biocompatible material to seal the communication between the perforation site and the gingival sulcus in order to achieve a more favorable prognosis. This review article is focussed on Biodentine as perforative repair material, and has found to provide good biocompatibility, bioactivity, high compressive strength and a short setting time.
