Abstract
The relationship between metrical and non-metrical fluctuating dental asymmetry was evaluated in three human population groups. Data were gathered for the Carabelli trait and the canine distal accessory ridge (CDAR) in 106 South African ‘Blacks’∗ (56 males, 50 females), 125 South African ‘Whites’† (59 male, 66 female) and 202 Paraguayan Lengua Indians (100 male, 102 female). When the levels of asymmetry for these two traits were compared to odontometric asymmetry of maxillary canines and first molars, a significant lack of association was noted. While Lengua Indians were found to be the least morphologically asymmetric, our data failed to offer an insight into the usefulness of fluctuating dento-morphological asymmetry as an indicator of environmental stress.
