Lustrous dentin of ivory of elephant is called what ..?
Answers
Ivory is a hard, white material from the tusks and teeth of animals, that consists mainly of d-e-n-t-i-n-e, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin.
Ivory poaching for tusks is the main reason that elephants have been so heavily hunted. Elephant ivory has been used in huge amounts to make billiards balls, piano keys, identification chops and many other items for human enjoyment.
Elephants usually have 26 teeth: the incisors, known as the tusks, 12 deciduous premolars, and 12 molars. Unlike most mammals, which grow baby teeth and then replace them with a single permanent set of adult teeth, elephants are p-o-l-y-p-h-y-o-d-o-n-t-s that have cycles of tooth rotation throughout their lives.
