PREVALENCE OF CUSP OF CARABELLI IN 652 TEETH AMONGST SOUTH INDIAN POPULATION

Background: The cusp of Carabelli, or Carabelli's tubercle, or tuberculum anomalum of Georg Carabelli is a small additional cusp at the mesiopalatal line angle of maxillary first molars. This extra cusp is usually found on the first molar, and becomes progressively less likely in the second, third molars. It is not found in all individuals. The cusp of Carabelli is a heritable feature. Carabelli's cusp is most common among Europeans (75-85% of individuals) and rarest in Pacific Islands (35-45%).Carabelli's cusp may rival the main cusps in size. The cusp of Carabelli trait was first described by Carabelli in 1842. Aim: To study the Prevalence of cusp of carebelli in an given population. To analysis first maxillary molar in different races (Indian, Srilankan, Malaysians, Chinese) Methods/Materials: At least 200 maxillary first molar is visually observed in patients and students of Saveetha dental college and hospital. Reason for the project: To justify that the presence of cusp of carebelli will vary for individuals from different races
