Effect of the addition of test compounds on S. mutans biofilms grown on resin ciments disks. (A) Biochemical data: (I) bacterial viability; (II) dry weight; (III) alkali-soluble polysaccharide; (IV) intracellular polysaccharide; (V) water-soluble polysaccharide. Different letters indicate a significant difference (p<0.05). (B) Representative SEM images of biofilm of S. mutans: (I) 20x and (II) 5000x.
