The aim of this study was to evaluate the in vitro antimicrobial activity of essential oils (EO) and fractions from highest activity EO against planktonic cells of mutans streptococci. Besides, the biofilms formed by this microorganism were submitted to active fractions and the higher activity EO and active fractions were evaluated regarding their citotoxicity and chemically characterized. For this, twenty essentinal oils were obtained from plants of the "Collectio of Medicinal and Aromatic Plants" (CPMA, CPQBA/UNICAMP), germplasm bank by hydrodistillation. These EO were evaluated by antimicrobial assays: minimum inhibitory (MIC) and bactericidal (MBC) concentrations against Streptococcus mutans UA159. Positive (chlorhexidine 0.12%) and negative (propylene glycol 6.12 % and 25%) controls were also tested...Note: The complete abstract is available with the full electronic document. (AU)
