Abstract
FluoroBondTM is one kind of fluoride releasing, visible light-activated bonding system for orthodontic bracket placement. The first aim of this study was to demonstrate the fluoride uptake by the human enamel adjacent to the bracket as well as by the human enamel beneath the bracket which was placed using FluoroBond. The second aim of this study was to investigate the acid solubility, of the human enamel in contact with FluoroBond for 30 days. The third aim of this study was to examine the teeth which produced artificial caries-like lesions after the attaching of the bracket using FluoroBond for 30 days in vitro.
The following results were obtained:
1. 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.
2. The acid solubility of the enamel was reduced by contact with FluoroBond. The reduction rate of 48 hours dissolution was 42.0%.
3. FluoroBond reduced the extend of demineralization adjacent to the bracket as well as beneath the bracket.
