The purpose of this study was to compare the fluoride release from a variety of orthodontic bonding agents, Fluoride release into de-ionized water was measured over a 20-week period. Material based on the fluoride exchange resin was also tested in a saline solution. Fluoride release from a variety of orthodontic bonding agent was compared and the amount of release found to be highly variable. Glass ionomer-based materials showed substantially greater fluoride release when compared with resin-based materials. The presence of anions (Cl−) did not improve the release from fluoride exchange resin.
Glass ionomer/resin hybrid material (Vitrabond®) released the greatest amount of fluoride.
