What syndromes are associated with supernumerary teeth?

Supernumerary teeth (ST) are odontostomatologic anomaly characterized by as the existence excessive number of teeth in relation to the normal dental formula. This condition is commonly seen with several congenital genetic disorders such as Gardner's syndrome, cleidocranial dysostosis and cleft lip and palate

cleft lip and palate

The Centers for Disease Control and Prevention (CDC) estimates that in the United States: About 1 in every 1,600 babies is born with cleft lip with cleft palate. About 1 in every 2,800 babies is born with cleft lip without cleft palate. About 1 in every 1,700 babies is born with cleft palate.

What is the cause of supernumerary teeth?

The causes of supernumerary teeth are uncertain, though factors that may contribute to their appearance include genetics, overactivity of the dental lamina (cells that initiate tooth development), disease processes, and atavism (the reappearance of a trait no longer common because of evolution).

What are the most common supernumerary teeth?

The most common type of supernumerary tooth is the mesiodens, which is a supernumerary tooth that forms between the upper two front teeth. Note that supernumerary teeth do not always erupt through the gums. In such cases, the supernumerary teeth may be visible only via dental X-rays.

Are 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 is Nance Horan syndrome?

General Discussion. Nance-Horan syndrome is a rare genetic disorder that may be evident at birth (congenital). It is primarily characterized by abnormalities of the teeth and clouding of the lens of the eyes (congenital cataracts), resulting in poor vision.

Supernumerary teeth

What is Dentinogenesis imperfecta?

Dentinogenesis imperfecta is a disorder of tooth development. This condition causes the teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent.

What is Turner's hypoplasia?

Turner's Tooth, also called Enamel Hypoplasia by professionals in the field, is a condition that reduces a tooth's enamel thickness, increases tooth sensitivity, leaves the affected tooth more susceptible to decay, and results in an unsightly appearance.

What is Amelogenesis imperfecta?

Amelogenesis imperfecta (AI) refers to a group of rare, inherited disorders characterized by abnormal enamel formation. The term is typically restricted to those disorders of enamel development not associated with other abnormalities of the body.

What is the most serious complication for infants with supernumerary teeth?

Complications associated with supernumerary teeth include impaction, delayed eruption, ectopic eruption, dental overcrowding, teeth spatial disorders, and the formation of follicular cysts.

What does hypodontia mean?

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 it to have 6 wisdom teeth?

These extra teeth, which can erupt after your original wisdom teeth have been extracted, are called supernumerary teeth. According to a 2015 study of more than 7,300 people, you have about a 2 percent chance of having supernumerary teeth.

What is cause Hypercementosis?

Hypercementosis is excessive deposition of cementum on the tooth roots. In most cases, its cause is unknown. Occasionally, it appears on a supraerupted tooth after the loss of an opposing tooth. Another cause of hypercementosis is inflammation, usually resulting from rarefying or sclerosing osteitis.

What is a Distomolar?

A distomolar is a supernumerary tooth which is located distal to third molars. They appear more frequently in men than in women. Several theories had been suggested to explain this phenomenon with the “dental lamina hyperactivity theory” to be the most accepted. Supernumerary molars (distomolars) are usually impacted.

What is Talon cusp?

Talon cusp is a dental anomaly also known as an eagle's talon. It is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. The exact etiology is unknown. The inci-dence of talon cusp is less than 6%.

What is Taurodontia?

Taurodontism is a developmental disturbance of a tooth in which body is enlarged at the expense of the roots. An enlarged pulp chamber, apical displacement of the pulpal floor and lack of constriction at the cementoenamel junction are the characteristic features.

How can you distinguish between amelogenesis and Dentinogenesis imperfecta?

Amelogenesis imperfecta vs.

This is a bone-like substance that makes up the middle layer of your teeth. Dentinogenesis imperfecta is caused by mutations in the DSPP gene. People with dentinogenesis imperfecta have teeth that are translucent and blue-grey or yellow-brown in color.

What is Hypocalcified amelogenesis imperfecta?

Definition. Hypocalcified amelogenesis imperfecta is characterized by enamel of normal thickness on newly erupted and unerupted and unresolved teeth. The enamel is soft and may be lost soon after eruption leaving the crown composed only of dentin. The enamel has a cheesy consistency and can be scraped from the dentin.

What does Abfraction mean?

An abfraction is a condition in which small notches, or lesions, develop near the gum line. These notches are often angular, however, they may become rounded over time as a result of abrasively brushing the teeth.

Is amelogenesis imperfecta and enamel hypoplasia same?

Enamel Hypoplasia can be related either to hereditary causes, affecting all the teeth on both dentitions or acquired ones, involving one or more teeth (Figure 3). When Hypoplasia is related to a hereditary cause it can be also called Amelogenesis Imperfecta.

What is Hutchinson's incisors?

Hutchinson's teeth is a sign of congenital syphilis. Affected people have teeth that are smaller and more widely spaced than normal and which have notches on their biting surfaces. It is named after Sir Jonathan Hutchinson, an English surgeon and pathologist, who first described it.

What is Genesis Imperfecta?

Osteogenesis imperfecta (OI) is an inherited (genetic) bone disorder that is present at birth. It is also known as brittle bone disease. A child born with OI may have soft bones that break (fracture) easily, bones that are not formed normally, and other problems. Signs and symptoms may range from mild to severe.

What is the difference between dentin dysplasia and dentinogenesis imperfecta?

A. Dentinogenesis imperfecta: The teeth are translucent and often roughened with severe amber discolouration. B. Dentine dysplasia: The primary teeth are translucent and amber in colour whereas the erupting secondary central incisors are of normal appearance.

What is Type 2 dentinogenesis imperfecta?

Overview. Dentinogenesis imperfecta type 2 is a rare and severe form of dentinogenesis imperfecta, a condition that affects tooth development. People affected by the condition may have weak and discolored teeth. These problems can affect both primary (baby) teeth and permanent teeth.

What is Parapremolar?

parapremolar n.

A *supernumerary tooth that forms in the premolar region and resembles a premolar tooth. ... General Links for this Work.

What is an enamel Pearl?

Enamel pearls are one of a number of different enamel structures that can be found on the roots of deciduous and permanent teeth. They have a distinct predilection for the furcation areas of molar, particularly the maxillary third and second molars.
