Examination for incidence of Carabelli's trait was done on 1267 Africans and 781 Asian school children, 298 dental plaster casts and 248 skulls of Africans. The African sample is composed of 80% Bantu, 20% Nilote, and Nilo-Hamitic people. When observed intraorally, the trait is present in 31-35% of Africans and 26-27% of Asians. In the dental casts and skull sample of Africans, the trait is present as pit in 23-28%, groove in 20%, and as tubercle and cusp in 22%. The total trait frequency in Africans is 68%.
