Sugar disrupts the equilibrium between acid- and alkali-producing bacteria. qPCR quantification of S. mutans (a), S. sanguinis (b), S. gordonii (c), and the ratios of S. mutans/S. sanguinis (d) and S. mutans/S. gordonii (e) in biofilm treated without or with sucrose/lactose/glucose. Results were presented as mean ± standard deviation. (n = 5; *p < 0.05; **p < 0.01; ***p < 0.001; ns, not significant; S. m = S. mutans; S. s = S. sanguinis; S. g = S. gordonii).
