RESUMO

The purpose of this study was to present a specific cephalometric dental pattern for young Brazilian afrocaucasian descendents, by obtaining the mean values of some dental cephalometric variables, and to analyse the prevalence or absence of dimorphism between genders. The sample comprised 40 lateral cephalograms, 20 of male (mean age of 13.15 years) and 20 of female (mean age of 13.10 years) subjects. All subjects were offspring from the miscegenation of Brazilian African and Caucasian adults. All subjects presented permanent dentition in occlusion, except for the third molars, and had not received previous orthodontic treatment. Cephalometric dental measurements were performed following the analyses of DOWNS, STEINER, RIEDEL, TWEED, McNAMARA, RICKETTS. Comparison between genders was performed by the independent "t" test. Data obtained from this methodology confirmed the absence of dimorphism between genders. Additionally, protrusion and buccal tipping of maxillary and mandibular incisors were observed, thus evidencing the adoption of a specific cephalometric pattern for this population.
