Cephalometric study of tooth position in young Afro-Caucasian Brazilian individuals with normal occlusion

Objective: The purpose of this study was to achieve a specific cephalometric pattern for young Afro-Caucasian Brazilian individuals and verify the presence of dimorphism between sexes. Methods: The sample was composed of 40 lateral cephalograms of young Afro-Caucasian Brazilian individuals (mulattos), 20 males (mean age 13.25 years) and 20 females (mean age 13.10 years), with normal occlusion and no previous orthodontic treatment. The cephalometric variables were determined according to the analyses of Downs, Steiner, Riedel, Tweed, McNamara, Ricketts and Interlandi. Independent t test was applied to compare the variables between sexes. Results: The maxillary and mandibular incisors were protruded and buccally tipped. There was no statistically significant difference between sexes in all variables. Conclusions: It was observed that young Afro-Caucasian Brazilian individuals without skeletal alterations and with normal occlusion showed specific tooth position and facial features in relation to the other Brazilian ethnic groups.
