BIOACTIVE GLASS COMPOSITIONS AND METHODS OF TREATMENT USING BIOACTIVE GLASS

摘要

A novel silica-based bioactive glass composition that can be used in conjunction with a delivery agent such as a toothpaste, gel, etc., having a particle size range < 90 .mu.m which will form a rapid and conti nuous reaction with body fluids due to the immediate and long-term ionic release of Ca and P from the core silica particles, to produce a stabl e crystalline hydroxy carbonate apatite layer deposited onto and into the dentin tubules for the immediate and long-term reduction of dentin hypersensitivity and tooth surface remineralization.
