Anodontia
Anodontia Definition
Anodontia, also known as anodontia vera in dentistry, is a very rare genetic disorder. This disease is characterized by congenital absence of all permanent and primary teeth. Anodontia is associated with a group of nerve and skin syndromes known as ?ectodermal dysplasias?. Anodontia is commonly part of different syndromes, which rarely occur as an isolated disorder. Partial anodontia, wherein the patient suffers from congenital absence of two or more teeth, could also occur. This is also known as ?oligodontia? and ?hypodontia?. Some patients may also suffer from congenital absence of all third molars and all wisdrom teeth.
