Dental crown variation was studied inthe four main population groups living in Malaysiausing dental casts (upper and lower) obtained from 790individuals. The aims of the study were to characterizevariation in 13 dental crown traits, within groups as wellas between groups, and to assess affinities between thegroups based on frequencies of occurrence of dentalfeatures. Using chi-square analysis and Fisher’s exacttest, the majority of dental traits were found to bebilaterally symmetrical and to demonstrate low sexualdimorphism. Comparisons of trait frequencies betweengroups revealed similarities between Malays, Jahai(Negritos) and Chinese who conformed to MongoloidSinodont-Sundadont dental patterns, whereas theIndians conformed to an Indo-European pattern.Phenetic distance analysis, using the mean measureof divergence, showed that Indians were markedlyseparated from the other three groups, while Malayswere closer to Jahai than to Chinese. These findingsbased on dental traits are consistent with historicalexplanations of affinities between modern Malaysianpopulations
