Abstract
The purpose of this study was to investigate the effect of Ag (NH3)2F on enamel surfaces. Both intact and artificially produced 'white spot' enamel slabs were treated with 38% Ag(NH3)2F solution. The uptake of F- and Ag+ ions was measured by etching these treated enamel slabs with HCl04. By the same method, the retention of F- and Ag+ ions was evaluated after immersing them in synthetic saliva. In addition, the enamel solubility of these samples was compared by measuring Ca2+ ions in acid solution. Finally, the remineralization was studied by means of microradiography, electron microprobe analysis and x-ray diffraction analysis. The following results were obtained:
