Developmental tooth disorders

Dens evaginatus is a condition found in teeth where the outer surface appears to form an extra bump or cusp.

Dental fluorosis (also termed mottled enamel) is an extremely common disorder, characterized by hypomineralization of tooth enamel caused by ingestion of excessive fluoride during enamel formation.

Dentinogenesis imperfecta (DI) is a genetic disorder of tooth development.

Kohlschütter-Tönz syndrome (KTS), also called Amelo-cerebro-hypohidrotic syndrome is a rare inherited syndrome characterized by epilepsy, dementia, intellectual disability, and yellow teeth caused by amelogenesis imperfecta (abnormal formation of tooth enamel).

Amelogenesis imperfecta (AI) presents with a rare abnormal formation of the enamel or external layer of the crown of teeth.

Macrodontia (or megadontia or megalodontia) is a type of localized gigantism in which teeth are larger than normal for the particular type(s) of teeth involved.

Microdontia is a condition in which one or more teeth appear smaller than normal.

An enamel pearl is a condition of teeth where enamel is found on locations where enamel is not supposed to be, such as on a root surface.

Dilaceration is a developmental disturbance in shape of teeth.

Supernumerary roots is a condition found in teeth there may be a larger number of roots than expected.

Enamel hypoplasia is a defect of the teeth in which the enamel is hard but thin and deficient in amount, caused by defective enamel matrix formation with a deficiency of vitamin D in the body.

In dentistry, hypodontia is the condition at which the patient has missing teeth as a result of the failure of those teeth to develop (also called tooth agenesis).

Taurodontism is a condition found in the molar teeth of humans whereby the body of the tooth and pulp chamber is enlarged vertically at the expense of the roots.

Regional odontodysplasia or odontogenesis imperfecta is an uncommon developmental abnormality of teeth, usually localized to a certain area of the mouth.

Talon Cusp is a rare dental anomaly.

Dens invaginatus, also known as dens in dente ("tooth within a tooth") is a condition found in teeth where the outer surface folds inward.

Tooth gemination is a dental phenomenon that appears to be two teeth developed from one.

Dentin dysplasia is a genetic disorder of teeth, commonly exhibiting an autosomal dominant inheritance.
