(b) Toluidine-blue-stained sections from a typical plaque biofilm. Sections i–vi taken at distances (from enamel surface) of approximately 820 µm, 730 µm, 560 µm, 390 µm, 220 µm, and 110 µm, respectively.

(a) Biofilms exposed to NaF for 30 sec, ± wash in saliva-like solution. (b) Biofilms exposed to NaF for 120 sec, ± wash in saliva-like solution. (c) Unexposed controls, and biofilms exposed to NaF for 30 min.
