The cusp of Carabelli in Malaysians.
The maxillary casts of 320 Malaysian children were examined for the occurrence of the Carabelli trait on the maxillary first permanent molars. The total trait frequency was observed to be 52.2 per cent. Statistical analysis showed no sex dimorphism in the occurrence of the trait. Bilateral occurrence with a tendency towards concordance of expression between sides was also observed.
