Abstract

The dental health of two Cambodian Iron Age (500 BC to 500 AD) communities is interpreted through an analysis of advanced wear, caries, periapical lesions, and antemortem tooth loss (AMTL). The two communities, Phum Snay and Phum Sophy, just 40 km apart, are temporally situated at a time of significant socio-political change prior to the establishment of Angkorian state rule. Dental pathology frequencies are compared between the two communities and with other prehistoric sites throughout Southeast Asia to determine whether dental health was affected by socio-political changes and the intensification of rice agriculture that also occurred at this time. The people of Snay and Sophy, despite their proximity, were found to exhibit significant differences in dental health. When subdivided by age and sex, Sophy older age class teeth had significantly more advanced wear, and older females had more periapical lesions, while the Phum Snay older age dentitions had significantly more AMTL. Caries rates were similar between the samples. When compared in the broader context of the Iron Age in prehistoric Southeast Asia, both Phum Snay and Phum Sophy suggest a trend of declining dental health during the period prior to the rise of the Angkorian state.
