The rate of progression of the demineralization front during acid demineralization is investigated for standardized elephant's ivory dentine specimens. A theoretical model for the penetration based upon a combined diffusion with reaction process is set up. It is demonstrated that the results are in accordance with the proposed model. For specimens of certain geometrical shapes (semi-infinite or plane sheet) the distance penetrated by the front is directly proportional to the square root of the time.
