The difference between histologic zones of an enamel lesion is primarily based on which property?

Differences among the histologic zones of an enamel lesion come from how much mineral has been lost from the enamel and how this loss changes pore space. Enamel is largely mineral (hydroxyapatite), so demineralization creates porosity and increases water-filled and air-filled spaces. The zones reflect progressively greater mineral loss: the areas with the least loss have smaller porosity, while deeper zones show more mineral loss and larger pores. Clinically observed color or thickness can vary with porosity and light scattering, but the fundamental distinction among zones is the degree of mineral content.
