RESUMO

Introduction: Remaining the diverse population in Brazil, the different ethnic groups can present unique skeletal and soft tissue measurements. Studies must be established to support orthodontics diagnostic and treatment plans between different races and different standards. Objective: Obtain mean normal values to soft tissue and skeletal cephalometric variables for Japanese-Brazilian and compare the values between Mediterranean, Japanese-Brazilian and Japanese descents. Methods: Cephalometric films were obtained from 40 Mediterranean, 32 Japanese-Brazilian and 33 Japanese adolescents. Only subjects with normal occlusion and well-balanced faces were selected. The variables were separately compared for males and females. ANCOVA, ANOVA and t tests were performed to compare the groups. Results: There were significant differences between the Mediterranean, Japanese-Brazilian and Japanese population in several variables tested for both sexes ( P<.05). The Japanese-Brazilian female have more protrusive lips, smaller nose and smaller nasion thickness when compared to the Caucasian sample and the Japanese-Brazilian male have greater glabellas thickness, smaller nasion thickness, greater lower lips and B point thickness and greater facial convexity. Conclusions: Japanese-Brazilian females showed more similarity characteristics to Japanese sample and males had numerically intermediate values with some variables been more similar to Mediterranean and other with the Japanese. Consequently, Japanese-Brazilian descents need a specific soft tissue standard.
