Abstract
Improved surface-characterization techniques are needed to study the adsorption of molecules and ions from aqueous solutions onto microcrystals of the biological mineral hydroxyapatite, the prime constituent of bone and teeth. The continuing development of techniques for obtaining high-resolution nuclear magnetic resonance (NMR) spectra from solids indicates that NMR could provide a valuable spectroscopic characterization of hydroxyapatite surfaces. We report here the successful application of new NMR techniques to two areas: (1) the adsorption onto the surface of hydroxyapatite of diphosphonates, used both as inhibitors of biological mineralization and as bone-scanning agents; (2) the reactions of hydroxyapatite with fluoride ion, which are important in the anti-caries benefits provided through fluoridation of dental enamel.
