Resinas compostas, Adesivos dentinários, Dentina, longevidade.Resumo
O presente trabalho objetiva realizar uma revisão crítica que busque esclarecer os mecanismos responsáveis pela degradação da união, assim como analisar as informações da literatura e propor medidas para a realização de restaurações mais duradouras. Apesar do avanço tecnológico que proporcionou o surgimento de resinas compostas mais estéticas e resistentes ao desgaste, esses materiais ainda apresentam problemas em relação à obtenção e preservação do selamento proporcionado pelo sistema adesivo. Revisando a literatura acerca dessa problemática, o ataque enzimático às fibras colágenas expostas, assim como a dissolução dos componentes do adesivo parecem explicar o mecanismo de degradação da adesão a longo prazo. Dessa maneira, mudanças no protocolo clínico como a aplicação de clorexidina ou EDTA têm sido propostas visando aumentar a estabilidade de união dente-restauração.Downloads
