Resumo
Objetivo: Avaliar o efeito remineralizante, bactericida e de pigmentação produzido por uma solução de fluoreto de sódio com nanopartículas de prata em comparação com o tratamento com Diamino Fluoride da marca SDI. Foram utilizados 40 dentes extraídos, desmineralizados com ácido fosfórico, depois colocados topicamente com Diamino Fluoreto e experimentalmente colocados em dois lados do mesmo dente e armazenados em saliva artificial a 37°C. A mineralização foi medida com o DIAGNOdent2095 (Kavo) sem tratamento e após a aplicação em 1 e 24 horas, 7 e 14 dias. A pigmentação foi comparada por meio de fotografias de microscópio estéreo. Os halos de inibição bacteriana foram testados em culturas de amostras de lesões cariosas de crianças em ágar salivarius e ágar tomate. Os resultados mostram uma remineralização total das amostras em ambos os tratamentos sem diferença estatística, com semelhança de inibição bacteriana, ligeiramente superior no Flúor Diamina em ágar salivarius. As áreas tratadas com o fluoreto experimental não apresentam pigmentação clínica, 75% das áreas tratadas com o fluoreto diamina apresentam pigmentação escura evidente. Em conclusão, o desempenho remineralizante e bactericida do fluoreto experimental é competente sem o efeito de pigmentação, tornando-o uma alternativa viável.
