  • Patent number: 6244871
    Abstract: 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 &mgr;m which will form a rapid and continuous 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 stable 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.
