Real-time biofilm formation of (a) S. mutans NCTC 10449 and (b) clinical isolate 2366 in BHI-sucrose medium or medium supplemented with 1, 2% or 5% xylitol and (c) S. mutans NCTC 10449 and (d) clinical isolate 2366 in BHI-sucrose medium or medium supplemented with 1, 2% or 5% erythritol. Bacteria were let to adhere on E-plate surface for 2 h, after which xylitol was added in the medium. dCI = cell index value change after addition of xylitol, see text for details. Mean ± SD, n = 4
