General Discussion

Anodontia is a genetic disorder commonly defined as the absence of all teeth, and is extremely rarely encountered in a pure form without any associated abnormalities. Rare but more common than complete anodontia are hypodontia and oligodontia. Hypodontia is genetic in origin and usually involves the absence of from 1 to 6 teeth. Oligodontia is genetic as well and is the term most commonly used to describe conditions in which more than six teeth are missing.

These conditions may involve either the primary or permanent sets of teeth, but most cases involve the permanent teeth. These phenomena are associated with a group of non-progressive skin and nerve syndromes called the ectodermal dysplasias. Anodontia, especially, is usually part of a syndrome and seldom occurs as an isolated entity.
