  • a Mean ± SEM (n = 28). P values are as follows: for S. mutans fimbriae, A versus B = 0.0001, A versus C = 0.0001, and B versus C = 0.9999; for CTB, A versus B = 0.0001, A versus C = 0.0187, and B versus C = 0.1362; and for whole cells (WC), A versus B = 0.0022, A versus C = 0.0019, and B versus C = 0.9985. Results for groups B and C were not significantly different (P > 0.05) as determined by Tukey’s procedure.
