The prevalance of a number of malocclusion traits was investigated for 1,000 modern British caucasoid, 70 medieval British, 60 Anglo-Saxon, 100 negroid and 100 mongoloid dentitions. Marked contrasts were evident in the sagittal, vertical and transverse occlusal and spacing anomalies between the various samples, with dental crowding being particularly prevalent in the modern British caucasoid sample and spacing between the teeth in the Anglo-Saxon sample. The method of quantification of malocclusions was shown to be applicable for other epidemiologic studies.
对1000例现代英国白种人、70例中世纪英国人、60例盎格鲁 - 撒克逊人、100例黑人及100例蒙古人种的牙列，研究了若干错颌特征的患病率。不同样本在矢状、垂直和横向咬合及间隙异常方面存在明显差异，牙列拥挤在现代英国白种人样本中尤为普遍，而牙齿间隙在盎格鲁 - 撒克逊人样本中较为常见。错颌的量化方法被证明适用于其他流行病学研究。
