Title:	Minerals in human teeth: differences between preindustrial and contemporary Hopi Indians
Date:	1977
Source:	American Journal of Clinical Nutrition
Abstract:	Mineral elements in dentin from 17th century Hopis were compared with samples from contemporary Hopis living in the same geographic area. Less lead, zinc, and copper, and more strontium were found in the preindustrial teeth. Trace element levels in the contemporary Hopi teeth were similar to those in suburban Californian teeth.
