definition

Collagen-rich odontogenic tissue characteristic of teeth and tooth-like skeletal elements (e.g., odontodes); mature dentine is mineralized and develops from predentine tissue; often (but not always) tubular and acellular.

external definition

Mineralized collagen containing substance that forms the tooth structure.[TAO]

dentine of tooth

dentin

has narrow synonym

taxon notes

Dentine is found in the fossil record as early as the late Cambrian, in fish, where it may have had a role in electrochemical sensing of the environment as well as assisting in defense[WP]
