A quantitative technique for obtaining angular data on human maxillary first premolar teeth is presented. Measurement indicates that North American Indian buccal cusps are either buccolingually compressed mesially, or expanded distally, or both, when compared with non‐Indian teeth. Surprisingly, data on Chinese and Eskimo samples are similar to non‐Indian teeth rather than Indian teeth. Similar techniques may be applied to the more complex multicusped molar teeth in order to extract quantitative data from them.
