title: Scanning electron microscopy of dentition: methodology and ultrastructural morphology of tooth wear.
abstract: Scanning electron micrographs were taken of sets of human molars-those of paleo-Indians used in mastication of, ostensibly, a highly abrasive diet, and those of contemporary Americans. Different ultrastructural patterns of enamel wear were observed between the groups.
