In Vitro Interproximal Enamel Fluoride Uptake as a Function of Fluoride Delivery Vehicles

Interproximal sites are often covered with a thin layer of saliva, which forms isocaps. These can restrict adequate delivery of therapeutic agents such as fluoride. Methods: Chemically demineralized enamel blocks were paired to simulate interproximal sites and exposed to human saliva to form isocaps. Enamel fluoride uptake (EFU) at these interfaces was studied using 220 ppm fluoride (F) rinse, 1.23% acidulated phosphate fluoride (Apf) gel, 5% sodium fluoride (NaF) varnish, and 2 novel vehicles – a pH nonacidic NaF disk (pHn disk), and an Apf disk, both containing 1.23% F and applied with or without NaF varnish...
