The mean number of Streptococcus mutans ATCC 25175 colonized on cementum surfaces were determined by average bacterial cells in ten randomly selected fields from each section (six sections in each group) and six SEM images for each section were captured. This experiment was independently repeated three times [41]. (A) CaP-F/Zn; (B) CaP-F; (C) CaP-Zn; (D) DDW (**p < 0.01; ^## p < 0.01; ^△△ p < 0.01)
