The dissolution kinetics at 37Β°C and for constant pH values of 5.0 and 6.0 are studied for calcium hydroxyapatite (HAp) equilibrated at pH 7.0 in the presence of 1 or 10 ppm of F-. Experiments are realized using an automatic setup which allows a continuous record of proton uptake and calcium or fluo
