BIOACTIVE GLASS – A VERSATILE BIOMATERIAL
Rakshith J.*
ABSTRACT
Regeneration of lost dental hard tissue is a significant contributing factors to long term success of the hard tissue treatment. Several bioceramic materials are now available with high degree of biocompatibility and bioinductive abilities. Bioactive Glass (BAG) is a novel biomaterial with primary components consisting of Silica, Calcium oxide and Phosphate. BAG was initially used as a bone regenerating material & is also found to promote new hydroxyapatite formation. The primary antimicrobial action of BAG is through its alkalinity and is effective against S.aureus and E.coli. In conservative dentistry BAG is used as a pulp capping material due to its ability to stimulate dentin bridge formation and deposition of secondary dentin. It is also capable of enamel remineralization and is used as dental adhesive. In endodontics BAG is used as an effective root canal sealer , perforation repair agent, retrograde filling material, pulp capping agent, repair of resorptive defects, apexification procedures and for pulpotomy procedure in due to its adhesive properties with tooth structure. BAG is used as a component in bioactive obturation materials such as the thermoplastic polymer based Resilon sealer. Bio Gutta, a gutta percha mixed with bioglass is a new alternative to classical GP cones as it does not require the use of a sealer and bonds to the dentin wall. The chemistry of BAG mimics the natural hard tissue composition and along with its bio inductive properties presents as an excellent biomaterial in the field of conservative and endodontics.
