Question

The teeth which are different in shape, size and function are called as

• A. Acrodont
• B. Pleurodont
• C. Homodont
• D. Heterodont

Answer 1

The correct option is D Heterodont

The teeth which are different in shape, size and function are called as heterodont. A heterodont is an animal which possesses more than a single tooth morphology. They generally possess incisors, canines, premolars, and molars. The presence of heterodont dentition is evidence of some degree of feeding/hunting specialization in a species.

In contrast, homodont dentition refers to a set of teeth that possess the same tooth morphology.

Acrodont is a formation of the teeth whereby the teeth are consolidated with the summit of the alveolar ridge of the jaw without sockets.

Pleurodont is a formation of the teeth that are fused by their sides to the inner surface of the jaw bones.
