Knowledge of the normal dentofacial patterns of various ethnic groups is important for clinical and research purposes. The objective of this study was to describe the dentofacial pattern of one Jewish ethnic group and to compare it with accepted standards for other white populations. Lateral cephalometric radiographs of 18 children of Jewish East European origin with clinically acceptable permanent occlusion, ages 11 to 13 years, were used. A computer-aided cephalometric analysis was performed, and the mean values and standard deviations for the various cephalometric variables were obtained. When compared with some classical standards, it was found that this ethnic group tended toward a mild skeletal Class II, a convex profile, and a more vertical direction of growth. These features appeared in persons selected on the basis of a clinically acceptable occlusion, suggesting the existence of dental compensations. Understanding these natural accommodations of the dentition to skeletal variations can be clinically useful when establishing treatment goals.
了解不同种族群体的正常牙颌面形态对于临床和研究目的都很重要。本研究的目的是描述一个犹太种族群体的牙颌面形态,并将其与其他白人人群的公认标准进行比较。使用了18名年龄在11至13岁、具有临床可接受恒牙咬合的东欧犹太裔儿童的头颅侧位X线片。进行了计算机辅助的头影测量分析,并获得了各种头影测量变量的平均值和标准差。与一些经典标准相比,发现这个种族群体倾向于轻度骨骼II类、凸面型和更垂直的生长方向。这些特征出现在基于临床可接受咬合选择的个体中,表明存在牙齿代偿。在制定治疗目标时,了解牙列对骨骼变异的这些自然适应性在临床上可能会很有用。
