Product Code Database
Enameloid, also known as durodentine or vitrodentine, is an Tooth enamel-like tissue found in fish. It is the primary outer component of shark (Shark tooth and dermal denticles), and modified forms of enameloid also occur in the teeth and scales of Actinopterygii (ray finned) fishes and stem-group Gnathostomata (jawed vertebrates). In extinct, armored jawless vertebrates such as Heterostraci, enameloid forms the outer component of shell-like dermal armor. Although the origin of enameloid is debated, it is probably homologous to rather than true enamel, despite its enamel-like strength and development. The term covers any hyper-mineralized tissue with an organic "scaffold" consisting of ectodermal and ectomesenchymal .
