Effect of CPP/ACP on Initial Bioadhesion to Enamel and Dentin In Situ

Figure 5

Effect of CPP/ACP (red), chlorhexidine (CHX) (blue), and saline solution (control) (black) on the viability of S. mutans in vitro. A suspension of S. mutans was incubated with CPP/ACP and chlorhexidine solutions in different concentrations. After incubation, the samples were admixed to proportions of the basic suspension. The amount of vital and dead bacteria was determined by BacLight bacterial viability assay. The measurements were carried out in duplicate and the ratio was calculated: emission 530 nm and emission 620 nm are representing emission vital and emission dead bacteria, respectively.
