Prolonged Inhibition of Streptococcus mutans Growth and Biofilm Formation by Sustained Release of Chlorhexidine from Varnish Coated Dental Abutments: An in Vitro Study

Figure 4

HR-SEM images of abutment-associated biofilm. The abutment-associated biofilms formed after 13 days of abutment exposure to S. mutans were visualized using HR-SEM. (a) Upper panel: SRV-placebo-coated abutments, 1, 2, and 3; lower panel: SRV-CHX-coated abutments, 1, 2, and 3. Magnification ×100. (b) Upper panel: SRV-placebo-coated abutments, 1, 2, and 3; lower panel: SRV-CHX-coated abutments, 1, 2, 3. Magnification ×5000.
