Popis: Summary: Streptococcus mutans is an important cariogenic microorganism, and alternative methods for its elimination are required. Different concentrations of Baccharis dracunculifolia essential oil (EO) were tested to determine its minimal inhibitory concentration (MIC) in planktonic cultures, and this concentration was used in S. mutans biofilms. Additionally, we assessed the effect of a 0.12% chlorhexidine (CHX) and saline solution in S. mutans biofilms. The biofilms were grown in discs of composite resin for 48 h and exposed to B. dracunculifolia, CHX or saline solution for 5 min. The viability of the biofilms was determined by counting the colony-forming units per milliliter (CFU/ml) in agar, which was statistically significant (P
