To determine the normality mean values in the soft tissue cephalometric measurements of young Japanese-Brazilian, with normal occlusion and to compare the results of the variables with compatible samples of young Caucasians and Mongoloids.
Forty radiographs of young Caucasians, 32 of Japanese-Brazilians and 33 of Mongoloids were used. The three samples presented individuals with normal occlusion and well-balanced face. The samples were divided by gender due to the soft tissue characteristics and to facilitate comparison. The following statistical tests were performed: Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) with p < 0.05.
The Japanese-Brazilian sample of females showed thinner soft tissues in the nasion region and smaller nose when compared to the Caucasians. The Mongoloid sample showed thinner tissues in the supramentonian and pogonion regions. In males, the Japanese-Brazilians had thinner tissues in the nasion region; thicker lower lip and supramentonian region in comparison to the Caucasian sample. For the Mongoloid, soft tissue was thicker in the glabella and ANS-Sn regions.
It is necessary to use specific soft tissue standards for this mixed race.
确定咬合正常的年轻日裔巴西人的软组织头影测量正常值，并将这些变量的结果与年轻白种人和蒙古人种的匹配样本进行比较。
使用了40张年轻白种人的X线片、32张日裔巴西人的X线片和33张蒙古人种的X线片。这三个样本中的个体咬合正常且面部比例协调。由于软组织特征并为便于比较，样本按性别划分。进行了以下统计检验：方差分析（ANOVA）和协方差分析（ANCOVA），p < 0.05。
与白种人相比，日裔巴西女性样本在鼻根区的软组织更薄，鼻子更小。蒙古人种样本在颏下点和颏前点区域的组织更薄。在男性中，日裔巴西人在鼻根区的组织更薄；与白种人样本相比，下唇和颏下区更厚。对于蒙古人种，眉间和前鼻棘-鼻下点区域的软组织更厚。
对于这种混血种族，有必要使用特定的软组织标准。
