Abstract

INTRODUCTION

McNamara's Jr. cephalometric analysis is a tool to diagnose dental and skeletal discrepancies and is widely used, guiding diagnosis for surgical procedures to be performed or for the use of functional devices. Few studies have shown that different ethnic groups have different cephalometric patterns. Thus, single characteristics should be respected to support the diagnosis and to help the treatment plan for different ethnic groups and their different patterns of miscegenation.

OBJECTIVE

Obtain normal values for McNamara's cephalometric analysis for adolescent Japanese-Brazilian descents with normal occlusion, as well as to compare this sample with similar samples of White-Brazilian and Japanese.

METHODS

Lateral headfilms from 40 White-Brazilian, 33 Japanese and 32 Japanese-Brazilian descents were selected. The three groups were composed by individuals with normal occlusion, well-balanced profiles and were separated by sex. The data were statistically analyzed with ANOVA, t-test, ANCOVA and MANCOVA tests.

RESULTS

White-Brazilian males had significantly greater nasolabial angle than Japanese males. Japanese-Brazilian displayed an intermediate value between White-Brazilian and Japanese.

CONCLUSION

White-Brazilian, Japanese and Japanese-Brazilian present different cephalometric characteristics of McNamara analysis. Japanese males have a significantly more acute nasolabial angle than White-Brazilian subjects.

摘要

简介

麦克纳马拉 Jr. 头影测量分析是一种用于诊断牙齿和骨骼差异的工具，被广泛应用，指导手术程序的诊断或功能设备的使用。很少有研究表明不同种族群体具有不同的头影测量模式。因此，应该尊重不同的特征，以支持不同种族群体及其不同的混血模式的诊断，并帮助制定治疗计划。

目的

获得具有正常咬合的青少年日裔巴西人麦克纳马拉头影测量分析的正常值，并将该样本与白种巴西人和日本人的类似样本进行比较。

方法

选择了 40 名白种巴西人、33 名日本人、32 名日裔巴西人的侧头部影片。这三组人群由具有正常咬合、均衡面部轮廓的个体组成，并按性别进行了区分。使用方差分析、t 检验、协方差分析和多变量协方差分析对数据进行了统计学分析。

结果

白种巴西男性的鼻唇角显著大于日本男性。日裔巴西人则显示出介于白种巴西人和日本人之间的中间值。

结论

白种巴西人、日本人、日裔巴西人具有不同的麦克纳马拉头影测量分析特征。日本男性的鼻唇角明显比白种巴西人更锐利。
