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 agents 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.
本研究的目的是比较多种正畸粘结剂的氟释放情况。在20周的时间内测量了氟向去离子水中的释放量。基于氟交换树脂的材料也在盐溶液中进行了测试。比较了多种正畸粘结剂的氟释放情况，发现释放量差异很大。与树脂基材料相比，玻璃离子基材料的氟释放量明显更大。阴离子（Cl-）的存在并未改善氟交换树脂的释放情况。玻璃离子/树脂混合材料（Vitrabond）释放的氟量最大。
