A rotating disk method has been used to study the dissolution of bovine enamel. A diffusion model adequately describes the reaction for a wide range of conditions, and the rate is also hydrogen ion dependent. The solubility product of bovine enamel, 5.9 ± 1.8 × 10-59 moles9 1-9 at 25 C is derived by a method that minimizes the possibility of phase changes.
