4 CONCLUSÃO GERAL

Nas condições desse estudo in situ, a terapia antimicrobiana fotodinâmica foi efetiva na redução microbiana em lesões de cárie dentinária.

 A terapia antimicrobiana fotodinâmica, utilizando uma fonte de luz LED (620-660 nm) na presença de azul de orto-toluidina, mostrou-se efetiva na redução de microorganismos totais, estreptococcos totais, estreptococos do grupo mutans e lactobacilos presentes em lesões de cárie dentinária produzidas in situ.

 Utilizando os parâmetros testados, a terapia não foi dose dependente e a irradiação prolongada da dentina teve efeito significativo na redução de todos os microrganismos testados. Assim, novos estudos devem ser realizados, a fim de estabelecer parâmetros adequados à utilização clínica da terapia antimicrobiana fotodinâmica.
