Fig. 5From: Thymol and carvacrol induce autolysis, stress, growth inhibition and reduce the biofilm formation by Streptococcus mutans Percent inhibition of the biofilm formation by S. mutans in the presence of test compounds. Values are presented are mean ± S.D error of three independent experiments. Dagger chlorhexidine digluconate was tested at a concentration of 2.5, 5, 10 and 20 µg/ml. Asterisk represents the p value <0.05 (refer to Additional file 1 for raw data)Back to article page
