Effects of UDMA on biofilm formation by S. mutans UA159 on a surface coated with saliva, and one not coated with saliva in a glucose-containing medium (a), and sucrose-containing medium (b), as determined by crystal violet staining. Number of viable cells in the glucose-containing medium (c), and sucrose-containing medium (d). Biofilms were formed in the presence and absence of a saliva coating on the surface. DMSO was used as a vehicle for UDMA, and cells not treated with UDMA served as the control (2% DMSO). Data are representative of three independent experiments, and are expressed as mean ± standard deviation values (Two-way analysis of variance).
