The mesiodistal crown diameters were measured in a group of fifty-six male American Negroes from the recruit population at the Great Lakes Naval Training Center and compared with previously reported data on Caucasians from the same population. The results indicate that tooth size is consistently larger in the Negro sample, averaging about 8.4 percent for the over-all maxillary and mandibular dentition, excluding third molars.
