Fig. 3From: Thymol and carvacrol induce autolysis, stress, growth inhibition and reduce the biofilm formation by Streptococcus mutans The change in the viability of S. mutans when grown with clove oil (CO), carvacrol (M-1; CAR), thymol (M-2; THY), and chlorhexidine digluconate (CHD). a Shows percent change in the metabolic activity of S. mutans using MTT assay with various concentrations of test compounds. While b shows the percent population of dead and live cells as determined by Live/dead staining when grown with test compounds. The experiment was done in triplicate and values are presented as mean ± S.D error. Asterisk represents the p value <0.05. Dagger the concentration of CHD is 2.5, 5, 10 and 20 µg/ml (refer to Additional file 1 for raw data)Back to article page
