Introduction
Biodentin is the first all-in-one bioactive and biocompatible dentine substitute based on unique Active Biosilicate TechnologyTM. It is designed to treat damaged dentine. It can be used for both for restorative and endodontic purposes.(1-8) Biodentin is superior to calcium hydroxide in terms of inducing dentinogenesis in human pulp tissue. Thus Pulp capping with Biodentin has gained popularity. Also, the pulp heal faster with Biodentin than calcium hydroxide.(9)
Use of BiodentineTM as a dentine substitute
BiodentineTM has easy handling along with excellent anatomic form. It shows very good marginal adaption. It also establishes a very good inter-proximal contact. Hence it is preferred to be used as a permanent dentine substitute…show more content… However in real practice, fractures may take place in the bond material, the substrate, or both which may extend beyond the initial bonded area. Thus fracture force of a bonded system is measured for a particular method of load application and hence should be interpreted as bond strength with caution.(13) Failure modes of Glass ionomer cement( 12,13) and Biodentine (14,15) to dentine were largely cohesive within the cement rather than at the interface. Therefore, interpretation of bond strength is significantly influenced by the rigidity of the…show more content… These oxides modify its chemical and physical properties. (2,18) Reactions occur at interface when GIC is applied to Biodentine. –COO of the Polyacrylic acid could interact with the calcium of biodentin to form calcium salts or the Silicate Hydrate gel of the biodentin could condense with the silicate hydrate gel of the GIC to form by product.(12) Biodentin contain mineral oxide which are ZrO2 (44.23 wt%), SiO2 (21.20 wt%). As the mineral oxides are higher in Biodentin, it is expected that Glass ionomer cement could bond strongly to
