Crown dimensions of deciduous teeth from pre-Columbian Peru

The mean mesiodistal and buccolingual diameters are presented for the deciduous teeth from Pre-Columbian Peru. Generally, the deciduous teeth from Pre-Columbian Peru are larger in most dimensions than the deciduous teeth of modern populations of European descent and smaller than those of modern Australian aboriginals. Differences in crown dimensions between the Pre-Columbian Peruvian deciduous teeth and those from Prehistoric Inamgaon and Mesolithic Europe are inconsistent. However, the maxillary and mandibular second molars are larger in the Peruvian population while the incisors are smaller. Since comparative data for prehistoric deciduous teeth are rare, this paper adds valuable data to the growing literature on deciduous crown dimensions.
