O presente estudo teve como objetivo avaliar e comparar o grau de conversão (usando a espectroscopia de infravermelho com transformador de Fourier), resistência à flexão e módulo de elasticidade (por teste flexão de três pontos), sorção e solubilidade da água e análise antimicrobiana (Concentração Inibitória Mínima e Concentração Bactericida Mínima - CIM e CBM, respectivamente) de infiltrantes experimentais contendo sal de difeniliodônio (DFI) e quitosana e do infiltrante da marca comercial Icon®. O grupo de infiltrante na concentração de 1% de DFI e 0,25% de quitosana foi o que apresentou os melhores resultados nos testes realizados. Esse grupo foi semelhante ao infiltrante comercial Icon® em todos os quesitos, tendo o diferencial de apresentar atividade bactericida que a marca comercial não apresenta. Concluindo que a adição de sal de DFI e quitosana são boas alternativas para a melhoria das propriedades mecânicas e antimicrobianas dos infiltrantes.
