This study evaluated the action of ethanolic extract of Myrciaria cauliflora (Mart.)O.Berg leaves on three Streptococcus cultures from dental plaque. Antimicrobial activity was assessed by agar-well diffusion method. The obtained data were satisfactory for all assayed species (Streptococcus mutans ATCC 25175, Streptococcus sobrinus ATCC 27609 and Streptococcus sanguis ATCC 10557) yielding inhibition halos when the pure extract and 1:2 and 1:4 dilutions were used. These results encourage new studies for the production of therapeutic compounds to be used in clinical dentistry.
