†Data are presented as the mean and standard deviation of three independent experiments (μM/OD). ‡Relative amount of each acidic end-product compared with the total amount of acidic end-products (%). G, 10 mM glucose; F, fluoride (mM). *P < 0.05; **P < 0.01; compared with the amount of acidic end-products produced in the presence of glucose.
