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].

current classification under substance of tooth may be turned into taxon GCI (e.g. sharks have enamel in dermal denticles)
Skeletal tissue that consists of an avascular, noncollagenous, hypermineralized matrix that is deposited by ameloblasts that are excluded from the matrix. Enamel develops from organic pre-enamel tissue that is replaced by a largely inorganic matrix.[VSAO]
