NEW USE OF BIOACTIVE SILICIOUS GLASS AND NEW COMPOSITIONS CONTAINING BIOACTIVE SILICIOUS GLASS

摘要

The invention concerns a novel use of bioactive silica containing glass. According to the present invention, the said glass is used for making a preparation which reduces the pulpal irritation of a tooth and/or strengthens the structure of a tooth. The invention also presents a pharmaceutical preparation, including a glass phase which is bioactive silica containing glass in the form of a paste, suspension or solution mixed in a physiologically suitable liquid or bound to a physiologically suitable vehicle, and which preparation reduces the pulpal irritation of a tooth and/or strengthens the structure of a tooth. Bioactive silica containing glass may be a material which contains only Si-oxide or Si-hydroxide and which allows the formation and movement of Si-OH-groups. Preferably, the preparation also comprises calcium and phosphate sources.
