Is oligodontia a disability?

Conclusions: Oligodontia is a heterogeneous condition. Patients with oligodontia can be classified as having three different types according to the extent of their disability and the complexity of their prosthodontic requirements.

What syndromes are associated with oligodontia?

Oligodontia can occur in association with various genetic syndromes, like ectodermal dysplasia, Van Der Woude syndrome, Down syndrome and Reiger syndrome or as a nonsyndromic isolated familial trait, or as an infrequent finding.

How is oligodontia treated?

Treatment of oligodontia requires a multidisciplinary approach. Prosthetic treatment includes removable partial dentures, fixed partial dentures and over dentures. Osseointegrated dental implants are also possible when there is adequate bone height as they offer a more stable, long-term solution.

Is missing permanent teeth genetic?

Congenitally missing teeth are teeth that never appear and are not trapped in the gums – they just do not exist in some people! The condition, which usually affects the lateral incisors and the second premolars, is often a harmless genetic trait passed down from parents to their children.

Are peg laterals hereditary?

Peg-shaped teeth are a hereditary dental disorder called microdontia, a condition where one or more teeth appear smaller than average (microdontia) [1]. In general, the most common teeth affected are the upper lateral incisors or sometimes third molars.

Is missing teeth a disability?

Therefore, an individual should be considered to have a dental disability if orofacial pain, infection, or pathological condition and/or lack of functional dentition affect nutritional intake, growth and development, or participation in life activities.

How common is missing permanent teeth?

Researchers estimate that as many as 20 percent of adults are born with at least one missing tooth, making hypodontia one of the most common developmental oral health conditions. Most individuals are missing only one or two permanent teeth, with very few missing more than six.

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/oligodontia/anodontia might be considered as a unique clinical entity but with increasing severity.

How common is anodontia?

The prevalence of anodontia is unknown but it is a very rare disorder. Anodontia occurs in less than 2-8% of the general population in regards to permanent teeth and 0.1-0.7% in primary teeth.

Is supernumerary teeth genetic?

Presence of supernumerary teeth is well-recognized clinical phenomenon. However, it is uncommon to find multiple supernumeraries in individuals with no other associated disease or syndrome. Presence of multiple supernumerary teeth is thought to have genetic component.

What are the commonest congenitally missing teeth?

The most common congenitally missing teeth are wisdom teeth, upper lateral incisors, and the second premolars(source).

Why are kids missing teeth?

Congenitally missing teeth may also be associated with various dental anomalies, such as cleft lip and palate, and genetic conditions, including Down's Syndrome. If a baby tooth is lost before it is ready to come out, other surrounding teeth can crowd into the vacant spot.

What is a ghost tooth?

Teeth in a region or quadrant of maxilla or mandible are affected to the extent that they exhibit short roots, wide open apical foramen and large pulp chamber, the thinness and poor mineralisation qualities of th enamel and dentine layers have given rise to a faint radiolucent image, hence the term "Ghost teeth".

What causes natal teeth?

The cause of natal teeth is unknown. Natal teeth may be more likely to occur in children with certain health problems that affect growth. This includes Sotos syndrome. The condition can also be linked to Ellis-van Creveld syndrome (chondroectodermal dysplasia), pachyonychia congenita, and Hallermann-Streiff syndrome.

What is the second tooth in hypodontia?

The second premolars – these are the teeth right in front of your molars. One may sometimes be removed during braces treatment, but if your child is missing this permanent tooth, chances are it's due to hypodontia.

What causes severe hypodontia?

Hypodontia is usually the result of a problem with the band of tissue under the gums (dental lamina) where the teeth form. The most common cause of these problems is heredity or family history. A mutation of one of the specific genes which help form the dental lamina properly can lead to hypodontia.

What does congenitally missing teeth mean?

If you are born with lesser teeth than an average person, you have hypodontia. It is also commonly known as congenitally missing teeth (CMT). It affects both baby and permanent teeth. The most common congenitally missing teeth are second premolars, wisdom teeth, and upper lateral incisors.

Can you be born with no 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. The most common missing teeth are wisdom teeth, upper lateral incisors, and second premolars/bicuspids.
