enamel's primary mineral is hydroxyapatite, which is a crystalline calcium phosphate.
the large amount of minerals in enamel accounts not only for its strength but also for its brittleness.
dentin, which is less mineralized and less brittle, compensates for enamel and is necessary as a support.
unlike dentin and bone, enamel does not contain collagen.
instead, it has two unique classes of proteins called amelogenins and enamelins.
