Material properties and clinical application status of Biodentine

Biodentine is a bioactive dentin replacement material whose main component is high-purity tricalcium silicate without dicalcium silicate. It has a shorter cure time; although it has a higher solubility, it hardly affects the volume of the material. It has a low X-ray barrier property, low porosity, high bulk density, and high compressive strength and is not affected by moisture or a dry environment. It has strong acid corrosion resistance, can increase dentin resistance, and has biocompatibility due to the lack of cytotoxicity. It has antibacterial activity against various bacteria, with strong antibacterial activity against Streptococcus sanguis. Since 2010, Biodentine has been widely used in clinical treatments such as dental restoration, pulp capping, pulpectomy, et al. In clinical applications, Biodentine is primarily used as a permanent dentin substitute or as a temporary enamel substitute within 6 months. As a new dentin substitute material with a short clinical application time, the long-term efficacy of Biodentine requires further follow-up observation studies.
