Studies to date show that extracellular fluid obtained from resting plaque is highly supersaturated with respect to enamel mineral and that, after one sugar rinse, it rarely becomes unsaturated, even though the pH decreases markedly. This is partly because Ca2+ is released from plaque pools and minimises the change in saturation level, that is, acts as a "saturation buffer". Theoretical considerations, however, suggest that, with repeated pH cycling, calcium and possibly phosphate and fluoride… CONTINUE READING
