  • a Data are mean viable populations of S. mutans, C. albicans, and total flora ± standard deviations (n = 11). —, not detected. Asterisks indicate that the values for the two infection groups are significantly different from each other (P, <0.05). The values for total flora do not differ significantly for the different infection groups (P, >0.05).
