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

Figure 1

Dental abutments before and after coating with SRV-CHX. Upper panel: three kinds of sterile dental abutments: GM PEAK healing abutment 5.5 × 2.5 mm [1] (a), GM titanium healing abutment 3.3 × 2.5 mm [2] (b), and GM titanium permanent abutment 4.5 × 6 × 2.5 mm [3] (c) were used for this study. Lower panel: the lower screw part of abutments 1, 2, and 3 were coated with the SRV-CHX ((d)–(f), respectively), and allowed to dry aseptically at room temperature.
