Figure 4From: Influences of naturally occurring agents in combination with fluoride on gene expression and structural organization of Streptococcus mutans in biofilmsInfluence of treatments on the pH values in the culture medium during S. mutans biofilm formation. The medium was replaced daily with fresh medium. The pH values (n = 9) were determined at 0 h and after 4, 8, 10 and 24 h of incubation each day. Values from vehicle control are significantly different from MFar250 at 10 h and 24 h of incubation, and from all treatments at 24 h of incubation during the entire experimental period (P < 0.05, ANOVA, comparison for all pairs using Tukey's test).Back to article page
