Efeito da utilização de dentifrícios com diferentes compostos bioativos nas propriedades superficiais do esmalte dental clareado

Thayne Waleska Yamamoto, Rubens Corte Real de Carvalho

Resumo

Este estudo tem como objetivo realizar uma revisão da literatura para verificar se os novos compostos bioativos presentes no mercado, CPP-ACP, fosfossilicato de cálcio e sódio e o nitrato de potássio são eficazes na remineralização do esmalte dental clareado. As alterações da superfície dental ocasionadas pelo clareamento são diversas. Duas novas técnicas de análise demonstram-se promissoras: o QLF e a nanoidentação. O QLF relaciona-se com a autofluorescência dental, possuindo vantagens relacionadas à sua especificidade, simples manuseio e preservação do espécime. Já a nanoidentação é capaz de mensurar a dureza em sítios específicos, em uma escala nanométrica, permitindo uma criteriosa seleção da área a ser analisada. O estudo concluiu que a literatura diverge quanto aos resultados dos efeitos do clareamento na superfície dental e os estudos que avaliaram os diversos compostos bioativos apresentam diferentes metodologias que não permitem o estabelecimento de um protocolo de aplicação dos mesmos. Sendo assim, faz-se necessária a realização de novos estudos para avaliar os possíveis efeitos dos diferentes compostos quando da utilização destes como dentifrícios de uso terapêutico após o tratamento clareador.

Palavras-chave
