Figure 2.
Mean values of biofilm fluorescence activities (vitality, CTC activity, EPS production) in S. mutans biofilm stacks after 24 h from the C (control), S (sucrose) and X (xylitol) conditions. Error bars indicate the 95% confidence interval. Statistical significance is denoted by asterisks (n=10). Cll, lower limit of the 95% confidence intervals; Clu, upper limit of the 95% confidence intervals; Con A, concanavalin A; CTC, 5-cyano-2,3-ditolyl tetrazolium chloride; EPS, extracellular polysaccharide.
