RESUMEN

The use of high-dimensional plots is explored in the evaluation of interpopulation differences in tooth size. Buccolingual and mesiodistal diameters were determined on the teeth of 202 Paraguayan Lengua Indians, 100 skeletal Blacks, 206 living South African Blacks and 125 living South African caucasoids. Multivariate discrimination between the four populations was effected by means of canonical variate analyses and stepwise discriminant analyses. These results were then compared to Andrews plots generated for males and females in each of these populations. Our results show that Blacks and caucasoids have significantly differing curves and that Amerindians share characteristics of both these groups.
