FluoroBond is one kind of fluoride releasing, visible light-activated bonding system for orthodontic bracket placement. The first aim of this study was to investigate the fluoride release from FluoroBond. The second aim of this study was to determine the fluoride uptake by human enamel which was immersed in distilled water for 30 days in contact with FluoroBond. The third aim of this study was to demonstrate the fluoride uptake by human enamel adjacent to the bracket as well as by the human enamel beneath the bracket which was placed using FluoroBond, and immersed for 30 days in distilled water. The results obtained were as follows. 1) A great amount of fluoride was released from FluoroBond immediately after immersion. The fluoride released weakend rapidly over the first 10 days. However, the fluoride released became stable after the 10th day. 2) The uptake of fluoride from FluoroBond was large both on the surface and the subsurface enamel in contact with it. 3) When FluoroBond was used as a bracket bonding material, fluoride was absorbed from FluoroBond by the enamel not only under the bracket but also adjacent to the bracket.

D003743 Dental Enamel A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath.
