A bioactive glass composition and a composition for treating teeth comprising the glass composition

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 mum 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.
