The objective is determining the frequency and variability, sexual dimorph, bilateral asymmetry and correspondence between twelve non-metric dental traits and two metric dental traits on the first and second upper and lower premolars in dental casts from 110 subjects from a Colombian racially mixed population. In this descriptive and quantitative study, frequency and variability of twelve non-metric dental crown traits were observed, through the ASUDAS (mesial and distal accessory crest and tricuspid premolar), Higa et al. (mesial and distal interstitial tubercle), van Reenen et al. (hypostile, bucal furrow, transverse ridge, meso-lingual furrow and disto-lingual furrow; and Hillson (lingual cusp number and groove pattern). The frequency of the metric and non-metric dental traits demonstrates that the first premolars present a minor dimensions and simplified morphology (caninization); whereas the second premolars ones are many characterized and of major size (molarization). The frequency of the non-metric dental traits is ambiguous; they do not present sexual dimorphism and present bilateral symmetry, with the exception of the meso-lingual furrow. The correspondence between the first and second upper and lower premolars changes in every trait. The dental dimensions present bilateral symmetry and sexual dimorphism with the exception of the second lower premolars. The dendogram suggests that the sample consists in mixed population with Caucasoid characteristics, negroid influence and mongoloid conservation. [ABSTRACT FROM AUTHOR]
