Fig. 1From: Casein phosphopeptide combined with fluoride enhances the inhibitory effect on initial adhesion of Streptococcus mutans to the saliva-coated hydroxyapatite discEffect of different concentrations of CPP on S. mutans initial adhesion. Salivary pellicle-coated HA disc was modified by two-fold serially diluted CPP solutions in the range of 0.15625–10%, followed by cultivation of S. mutans for 30 min and 2 h. Colony forming units (CFU) counts of S. mutans per disc were determined and the results were expressed as the mean ± SD. **p < 0.01, ****p < 0.0001 compared with the control groupBack to article page
