This article discusses variations in dentogenesis and their consequences when estimating age in archaeological samples. One example described here, taken from a sample of a Lagoa Santa primeval population found in the Santana do Riacho rock shelter in the state of Minas Gerais, Brazil, suggests a need for more research concerning patterns of dental growth and maturation in South American indigenous populations.
