Is hypodontia a medical condition?

Hypodontia is the most prevalent dentofacial malformation in humans [1]. It may occur as part of a recognised genetic syndrome or as a nonsyndromic isolated trait [2]. The condition refers to the developmental failure of six or fewer teeth [3].


Is hypodontia a condition?

Hypodontia is a congenital condition characterized by one to six missing teeth.

Is hypodontia a genetic disorder?

Hypodontia is genetic in origin and usually involves the absence of from 1 to 5 teeth. Oligodontia is genetic as well and is the term used to describe a condition in which six or more teeth are missing.

Hypodontia treatments include getting dental implants, getting bridges and dentures. While replacing the missing teeth is a common recommended approach, you may not require that but, just braces and other less invasive treatments. Most adults who had missing teeth as children may have missing teeth as adults.

Hypodontia can also result from environmental factors, such as trauma, radiation or chemotherapy (Schalk-van der Weide et al., 1993; Näsman et al., 1997). Therefore, non-syndromic hypodontia can occur sporadically or in a familial form.

It was suggested, that severe hypodontia causes a lack of occlusal support, which results in an underdevelopment of the lower face and anterior rotation of the mandible, leading to prognathism of the lower jaw [16].

What mutations cause hypodontia?

MSX1 gene mutations have been associated with premature termination of tooth development in animals [2, 21] and severe forms of hypodontia in humans. Recently, however, a frameshift mutation in MSX1 has been identified in a family missing all second premolars and mandibular central incisors [62].

Why do some people have no teeth?

Tooth decay, gum disease, and injury are common causes of missing teeth. 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.


When is hypodontia diagnosed?

It is a common dental issue where teeth fail to develop normally from childhood. You can be diagnosed with hypodontia if there are any congenitally missing permanent teeth in your mouth. Hypodontia is diagnosed in childhood if parents are alert and notice missing teeth in kids.

What is severe hypodontia?

Severe hypodontia is the absence of six or more permanent teeth and is relatively uncommon (estimated prevalence of 0.1-0.2%). This condition may have considerable functional, aesthetic and psychological implications for the patient, as well as presenting a significant challenge for the restorative dentist.


Is hypodontia recessive?

Hypodontia may be inherited in an autosomal recessive, autosomal dominant, X-linked dominant, or X-linked recessive mode. The most commonly missing permanent teeth are the third molars (20%), second premolars (3.4%), and maxillary lateral incisors (2.2%) (Simons et al. 1993).

Can braces fix hypodontia?

While braces work for some hypodontia problems, they aren't likely to work if the gap is too big or if your child has multiple gaps in the same part of the mouth. If existing teeth can't cover the gap without moving too much themselves, then your teen needs a different solution.

Can having no teeth affect your health?

Tooth loss has been linked to heart disease, diabetes, and an increased risk for kidney disease. Gum disease and severe infections in the mouth can spread to other parts of the body faster than people realize. A healthy mouth is alkaline. It's vital for you to maintain an alkaline pH to keep harmful bacteria away.


Can you live a healthy life without teeth?

You will notice this as a sunken look to your face or a shorter face (than normal).

Does Down syndrome have hypodontia?

Hypodontia is often seen in people with Down syndrome (DS). In the normal population, persons with hypodontia have a shorter cranial base and a hypoplastic maxilla, leading to a skeletal Class III tendency and a reduced face height.


What are 5 features recognized in a Down's syndrome individual?

  • A flattened face, especially the bridge of the nose.
