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

Figure 1

DAPI staining (blue) and live/dead staining (red/green): representative images of CPP/ACP samples and control-specimens (CHX, no rinse) after 8 h oral exposure. On enamel control samples vast areas were coated by bacterial aggregates or monolayers; dentin samples show a preferred colonization at the dentin tubules. Initial rinses of chlorhexidine reduced the bacterial adhesion considerably. CPP/ACP had no impact on the amount of adherent bacteria, as compared with unrinsed controls.
