'This is the second edition of The Anthropology of Modern Human Teeth: Dental Morphology and its Variation in Recent Human Populations (1997). Scott and Turner, authors of the first edition, studied dental variants and the two major patterns of Mongoloid dental variation, Sundadont and Sinodont, were described. Their dental trait evaluation system, the ASUDAS (Arizona State University Dental Anthropology System), has become an essential tool for dental anthropological researchers worldwide. In the first edition, morphological variations in dental traits were described. In the second edition, the ontogenetic, genetic and evolutionary aspects of these traits have also been covered. The authors also describe how advances in dental studies will become even more dramatic over the next twenty years. This is a classic text that is well written, beautifully illustrated and extensively referenced, and it will undoubtedly become a compass for younger researchers responsible for the next generation of dental anthropological research.'
