In a study of maxillary right first premolar morphology, multivariate analysis showed varying degree of separation between four human ethnic groups depending upon the actual metrical profile included in the analysis. Such ethnic discriminations were not possible from visual inspection or univariate analysis of individual crown diameters. Although the interpretation of such ethnic contrasts remains obscure, this study demonstrated the potential of multivariate statistical techniques in the investigation of odontometric data.
在一项关于上颌右侧第一前磨牙形态的研究中，多变量分析表明，根据分析中所纳入的实际测量特征，四个人类种族群体之间存在不同程度的差异。通过目视检查或对单个牙冠直径进行单变量分析，无法进行此类种族区分。尽管此类种族差异的解读仍不明确，但这项研究证明了多变量统计技术在牙测量数据研究中的潜力。
