What causes oligodontia?
Possible causes of oligodontia include viral disease during pregnancy, genetic predisposition, metabolic imbalances, developmental abnormalities and environmental factors. Autosomal dominant mutations in PAX9 and MSX1 have been found in patients with molar non-syndromic oligodontia.
What type of mutation causes oligodontia?
WNT10A mutations are the most commonly reported in the genetic etiology for syndromic oligodontia and PAX9 mutations are the most commonly reported genetic etiology for isolated oligodontia. Oligodontia is not only a disorder of missing teeth but also a clinical sign of a potentially complex systemic condition.
Is oligodontia a genetic disorder?
Oligodontia is genetic as well and is the term used to describe a condition in which six or more teeth are missing. Hypodontia/oligodontia/anodontia might be considered as a unique clinical entity but with increasing severity.
Is oligodontia a birth defect?
According to the Oral Health Group, this is the most common congenital (affects you from birth) condition in humans. Oligodontia is a specific type of agenesis that causes you to be born without six or more teeth (not counting wisdom teeth). Causes of teeth absent from birth include: Genetic syndromes.
What percentage of people have oligodontia?
It is a relatively rare condition affecting 0.1–0.2 % of the population. Oligodontia can occur as an isolated nonsyndromic condition or as a part of a syndrome.
Can missing teeth be genetic?
Some people are born without certain teeth, and this condition is called congenitally missing teeth. Genetic factors cause congenitally missing teeth and this condition is often seen in generations of a family. The most common missing teeth are wisdom teeth, upper lateral incisors, and second premolars/bicuspids.
Do Native Americans have extra teeth?
The reported incidence of supernumerary teeth ranges 0.3–1.7% of the population with greater frequency in Asians and Native Americans. According to previous studies, supernumerary teeth more frequently found in permanent dentition with a male predilection.
What is anodontia?
Anodontia is a dental condition characterized by complete absence of teeth. The primary (baby) or permanent (adult) teeth may be involved. In most cases, the condition is associated with a group of conditions called the ectodermal dysplasias.
What race has no wisdom teeth?
But the Inuit, a group of people who live in the Arctic regions of Canada, Greenland and Alaska, have the fewest wisdom teeth; about 45 percent of them lack one or more third molar, he said. There are probably a couple reasons for this.
Can you tell your ancestry by your teeth?
Your teeth can indicate facets of your recent ancestry and may even provide information about the long dead evolutionary past. That’s why knowing more about teeth and how they develop and grow is valuable for people other than your dentist.
