A study of multiracial malocclusions.

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.
