Dental caries, prehistoric diet, and the pithouse-to-pueblo transition in southwestern Colorado

Researchers in different parts of the southwestern United States continue to debate whether the end of the Basketmaker period coincides with a general shift from supplemental to intensive maize agriculture. across the U.S. Southwest. In some areas this transition appears to have occurred earlier, with heavy reliance on agriculture appearing by the Basketmaker H period. In this study, evidence from dental caries in southwestern Colorado populations supports the latter view, suggesting that Basketmaker subsistence in this area included a heavy reliance on agricultural products. Dental caries frequencies in both Basketmaker and post-Basketmaker samples are well within the expected range for,full-time agriculturalists. Although there is no significant association between time period and caries rate, frequencies of interproximal caries and numbers of carious teeth per individual may indicate maize-processing differences between samples obtained from the two temporal periods. Differences in the intensity of maize production, rather than consumption, may contribute to the current lack of agreement on the timing of Southwestern agricultural dependence.
