| Popis: | Diffusion fluxes of two anionic species through hydroxyapatite membranes were found to be reduced up to 50% by the presence of adsorbed salivary pellicles developed on the membrane surfaces. By contrast, water fluxes were only marginally affected, indicating that salivary pellicles display ionic permselectivity. This property is used to explain a remarkable protection of the enamel observed when salivary pellicles were developed on extracted teeth before exposure to acid lactate buffers. |
