Cusp of Carabelli

Cusp of Carabelli is a supplemental or extra cusp found on the mesiopalatal surface of the maxillary first molar, specifically the maxillary first molar. The cusp is named after Georg Carabelli, an Austrian dentist who first described it in the 19th century.

Description

The Cusp of Carabelli is a conical or tubercle-like elevation that is variable in size and shape. It is most commonly found on the mesiopalatal cusp of the maxillary first molar, but can also be found on other teeth. The presence of the cusp is considered a normal variant of tooth morphology.

Prevalence

The prevalence of the Cusp of Carabelli varies widely among different populations. It is most commonly found in people of European descent, with a prevalence rate of up to 80%. It is less common in people of Asian, African, and Native American descent.

Clinical significance

The Cusp of Carabelli can have clinical significance in dentistry. It can affect the occlusion of the teeth and may require modification during restorative procedures. In addition, the cusp can present challenges in tooth cleaning and may be associated with an increased risk of dental caries.

History

The Cusp of Carabelli was first described by Austrian dentist Georg Carabelli in the 19th century. Since then, it has been the subject of numerous studies investigating its prevalence, genetic basis, and clinical significance.
