Resumo

Objective: Performing a screening of Amazonian species as antimicrobial action of oral biofilm micro-organisms in vitro. Methods: Determining the Minimum Inhibitory Concentration (MIC) for solid medium diffusion and Minimum Inhibitory Concentration of Adherence (MICA). The strains tested were S. sobrinus (ATCC 27609), S. mutans (ATCC 25175), S. mitis (ATCC 9811); S. sanguis (ATCC10556), L. casei (ATCC 7469).Results: Juca, Crajiru, Alfavaca and Copaiba presented MIC with halos of inhibition for all strains tested, with values of 62.5, 500, 1000 and 1000 mg/mL, respectively. In MICA, extracts of Juca, Jambu and Crajiru inhibited the adherence in all strains tested. Conclusions: Extracts of Juca, Crajiru, Alfavaca and Copaiba essential oil had antimicrobial activity against the strains tested and extracts of Juca, Crajiru, Alfavaca, Jambu and Copaiba and Andiroba oils inhibited microbial adherence.
