RESUMO
The non-metric traits in tooth morphology, for their excellent preservation, and inter-population variation, immune from selection pressure, are known to be one of the major sources of observation for researchers who analyze human variation and its relationship to the populations biological history. In a forensic context, the knowledge of the local morphological characteristics allows its use as additional criterion for human identification purposes. Objective: This study has proposed an anthropological analysis of tooth morphology of Brazilian individuals from Rio de Janeiro, between 18 and 30 years, listing the prevalence of some anthropological non-metric traits, their relationship with frequencies found by other researchers, in different populations, and its value as additional criterion for in human identification. Methodology: The dental casts of 130 individuals (59 males and 71 females) were examined, with the following inclusion criteria: Brazilian naturality, with Brazilian ascendency until second degree, presence of at least two of the target-teeth healthy, and absence of blood relationship with other participants. We evaluated the presence of six non-metric dental traits with populational frequencies previously published by other authors, as follows: shoveling, Carabelli s cusp, cusp 5 (distal accessory tubercle), hypocone absence, cusp 6, and hypoconid absence. Results: The frequencies of all the traits evaluated differ from frequencies previously presented for Amerindian and South American. The sample has little resemblance to the so called american dental complex, and strong influence of the African Sub-Sahara and European patterns, which is in agreement with local historical events
