  1. Negative control: salivary pellicle-coated HA; Heat-inactivated CPP, CPP and CPP + F: salivary pellicle-coated HA modified by heat-inactivated 2.5% CPP, 2.5% CPP, and 2.5% CPP supplemented with 900 ppm fluoride. Data are expressed as the mean ± SD. Within columns (water contact angle or zeta potential), different superscript letters (a, b, c, d) indicated significant difference (p < 0.05)
