RESUMO

OBJECTIVE: The objective of this study was to identify the standards for skeletal and dental measurements of adolescent Japanese-Brazilian descents with normal occlusion and also to compare it with a similar White and Japanese sample. MATERIAL AND METHODS: Lateral cephalometric radiographs were used with the purpose of comparison between the groups: White (N=40), Japanese-Brazilian (N=32) and Japanese (n=33). The statistical tests were the t test and ANCOVA. Basically, the cephalometric measurements used followed the analyses of Steiner (1953), Tweed (1954) and McNamara Jr (1984). RESULTS: The statistical differences (p <.05) indicated a more accentuated vertical pattern, smaller interincisal angle and overbite for the Japanese-Brazilian sample, when compared to the White sample, although with similar values to the Japanese group. CONCLUSION: The skeletal and dental standards found for the Japanese-Brazilian descents were, in general, similar to those of the Japanese sample but diverse to the White sample. This empowers the necessity to discern this Japanese-Brazilian descents pattern.
