Figure 2 Scanning electron microscopy images of Enterococcus faecalis-infected dentin blocks treated with saline and chlorhexidine. Blocks treated with saline solution for 10 min show many adhering Enterococcus faecalis (A, × 1500) with normal shape (B, × 20000). The group soaked with 2% chlorhexidine shows fewer adhering bacteria (C, × 1500) and chlorhexidine particles attached to bacterial membranes (D, × 20000, white arrows)[28].
