AIM: The aim of this study is evaluate the antimicrobial activity of the Ocimum basilicum L. (basil) extract  and of the Coriandrum sativum L. (coriander) extract in biofilm of Streptococcus mutans colonized in specimens confectioned in acrylic used to confection removable orthodontic appliances. MATERIAL AND METHODS: To perform this work, specimens were confectioned (spherical discs in sterile acrylic) which were immersed in extracts pure and in series dilutions (1:2 a 1:128) by 24, 48 and 72 hours. For each time of exposition, the disintegration of bacterial films was performed by sonication in saline solution. RESULTS: The results obtained were satisfactory for the extracts studied on the inhibition of biofilm formation. CONCLUSION: We conclude that polyphenols present in the extracts interfered on the glucan synthesis engine, possibly inhibiting the enzymes (glucosyl- and fructosyl transferase) which synthesize the extracellular polymers, also acting as antioxidant, and therewith they presented antimicrobial activity.
