Use of the modified robbins device and fluorescent staining to screen plant extracts for the inhibition of S. mutans biofilm formation.
Streptococcus mutans plays an important role in the formation of dental plaque. To study biofilm growth on hydroxyapatite (HA) in vitro, a flow system based on a Modified Robbins Device (MRD) and a method for the quantification of the biomass using fluorescent staining with SYTO(R) 9 were developed. The combined approach was used to assess the inhibitory effect of plant extracts on biofilm formation in concentrations below their minimal inhibitory concentrations.
