enamel
http://purl.obolibrary.org/obo/UBERON_0001752
A dentine-like hypermineralized substance that covers the tooth tip. Enamel's primary mineral is hydroxylapatite, which is a crystalline calcium phosphate. Unlike dentin and bone, enamel does not contain collagen. Instead, it has two unique classes of proteins called amelogenins and enamelins[WP].
