Supernumerary root

Supernumerary root is a dental condition characterized by the presence of an extra root in a tooth that normally has one or two roots. This condition is relatively rare and can occur in any tooth, but it is most commonly found in the molar teeth.

Causes

The exact cause of supernumerary roots is not known. However, it is believed to be a developmental anomaly that occurs during the formation of the tooth. Some researchers suggest that it may be due to genetic factors, while others believe that it could be related to environmental factors such as trauma or infection during tooth development.

Diagnosis

Diagnosis of supernumerary roots is usually made through dental radiographs. These can show the presence of an extra root, although it may not always be visible if the root is small or overlapped by other structures. In some cases, a CT scan may be needed to confirm the diagnosis.

Treatment

Treatment for supernumerary roots depends on the symptoms and complications associated with the condition. If the extra root is causing pain or other problems, it may need to be removed. This is usually done through a procedure called root canal therapy, which involves removing the pulp from the root and then filling and sealing the root canal. In some cases, the entire tooth may need to be extracted.

Complications

Supernumerary roots can cause a number of complications. They can make root canal therapy more difficult, as the extra root can be hard to locate and treat. They can also increase the risk of periodontal disease, as the extra root can create a space where bacteria can accumulate. In addition, they can cause problems with tooth alignment and bite, and can make it more difficult to place dental implants.
