The use of high-phosphorus supplements to inhibit dental enamel demineralisation by ice lollies

Five new formulations of water ice lollies with a high-phosphorus (low Ca) supplementation ratio were tested for their erosiveness of dental enamel or hydroxylapatite in vitro. Compared with the basic unsupplemented lolly, all five formulations that had been prepared with additional calcium and phosphorus, but in a low Ca/P ratio, as potential inhibitors of demineralisation, were associated with significantly less attack on dental mineral, as measured by the dissolution of calcium and phosphorus.
