The Cusp of Carabelli, or Carabelli's tubercle, or tuberculus anomalus of Georg Carabelli is a small additional cusp at the mesiolingual line angle of maxillary first molars. This cusp is entirely absent in some individuals and present in others in a variety of forms. In some cases, Carabelli's cusp may rival the main cusps in size. Other related forms include ridges, pits, or furrows. This additional cusp was first described in 1842 by Georg Carabelli, a court dentist of the Austrian Empire|Austrian Emperor Franz.
The cusp of Carabelli is a heritable feature. Kraus (1951) proposed that homozygosity of a gene is responsible for a pronounced tubercle, whereas the heterozygote shows slight grooves, pits, tubercles or bulge. Later studies showed that the development of this trait is affected by multiple genes. Carabelli's cusp is most common among Europeans (75-85% of individuals) and rarest in Pacific Islands (35-45%).
