Abstract

COMPOSIçõES DE VIDRO BIOATIVO E MéTODOS DE TRATAMENTO UTILIZANDO VIDRO BIOATIVO. Uma nova composição de vidro bioativo à base de sílica que pode ser utilizada em conjunto com um agente de distribuição, tal como uma pasta de dente, gel, etc., tendo uma faixa de tamanho de partícula < 90<109>m que formará uma reação rápida e contínua com fluidos corpóreos devido à liberação iónica imediata e duradoura de Ca e P das partículas de sílica do núcleo para produzir uma camada de apatita de hidróxi carbonato cristalina estável depositada sobre e nos túbulos de dentina para a redução imediata e duradoura da hipersensibilidade da dentina e remineralização superficial do dente.
