[Relative concentration of phosphorus and calcium in the ameloblastic layer and in the enamel. Preliminary study (author's transl)].
It may be inferred from this observation, that all of the phosphorus necessary to the formation of the enamel, reaches it, during its formation process, by way of compounds, formed in the ameloblastic layer, and containing only part of the calcium necessary to the crystallisation of the hydroxyapatite. The remainder of the calcium may attain, by another route, the enamel under formation where the hydroxyapatite crystallises.
