Hyperdontia

Hyperdontia is a condition characterized by the presence of an excessive number of teeth in the mouth. These extra teeth are referred to as supernumerary teeth. Hyperdontia can occur in both the primary dentition and the permanent dentition.
Types of Supernumerary Teeth
Supernumerary teeth can be classified based on their location and morphology. The most common types include:
- Mesiodens: These are extra teeth that occur in the midline of the maxilla, between the two central incisors. Mesiodens are the most common type of supernumerary teeth.
- Paramolars: These are extra teeth located buccally or lingually to the molars.
- Distomolars: Also known as "fourth molars," these are extra teeth located distal to the third molars.
- Supplemental teeth: These resemble the normal series of teeth and are often found in the incisor or molar regions.
Causes
The exact cause of hyperdontia is not well understood, but it is believed to involve a combination of genetic and environmental factors. It is often associated with certain genetic disorders such as Cleidocranial dysostosis and Gardner's syndrome.
Diagnosis
Hyperdontia is typically diagnosed through clinical examination and dental radiography. Panoramic radiographs and cone beam computed tomography (CBCT) are commonly used to assess the number, position, and morphology of the supernumerary teeth.
Treatment
The treatment of hyperdontia depends on the type, number, and position of the supernumerary teeth, as well as the presence of any associated complications. Treatment options may include:
- Observation: In cases where the supernumerary teeth are not causing any problems, they may be left in place and monitored over time.
- Extraction: Supernumerary teeth that cause crowding, impede eruption of normal teeth, or lead to other dental issues are often extracted.
- Orthodontic treatment: In some cases, orthodontic treatment may be necessary to correct any malocclusion or alignment issues caused by the presence of supernumerary teeth.
Complications
Hyperdontia can lead to several complications, including:
- Dental crowding
- Impaction of adjacent teeth
- Malocclusion
- Cyst formation
- Delayed or ectopic eruption of permanent teeth
