title: A metrical comparison of maxillary first premolar form.
abstract: 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.
