title: Comparative study of dental cephalometric patterns of Japanese-Brazilian, Caucasian and Mongoloid patients.
abstract: BACKGROUND
  The objective of this study was to identify the patterns of dental variables of adolescent Japanese-Brazilian descendants with normal occlusion, and also to compare them with a similar Caucasian and Mongoloid sample.
  
  
  METHODS
  Lateral cephalometric radiographs were used to compare the groups: Caucasian (n = 40), Japanese-Brazilian (n = 32) and Mongoloid (n = 33). The statistical tests used were one-way ANOVA and ANCOVA. The cephalometric measurements used followed the analyses of Steiner, Tweed and McNamara Jr.
  
  
  RESULTS
  Statistical differences (P < 0.05) indicated a smaller interincisal angle and overbite for the Japanese-Brazilian sample, when compared to the Caucasian sample, although with similar values to the Mongoloid group.
  
  
  CONCLUSIONS
  The dental patterns found for the Japanese-Brazilian descendants were, in general, more similar to those of the Mongoloid sample.
