Dental disease and dietary patterns in coastal Phoenicia during the Roman period

The current paper presents one of the first bioarchaeological studies on dental disease and dietary patterns in coastal Phoenicia during the Roman period, focusing on the dentition of 145 adults from the contemporary and geographically proximal sites of Byblos, Beirut, and Tyre. Pathological conditions of the oral cavity and dental wear were used to assess intra-assemblage and inter-assemblage differences. Byblos in almost all instances exhibited higher levels of dental diseases and wear than Beirut and Tyre, suggesting a greater consumption of carbohydrates but also poorer oral hygiene and greater mechanical stress (dental wear) in this community. This difference between Beirut/Tyre and Byblos may be explained by the politico-economic status of these cities as textual sources highlight the economic and political prowess of Beirut and Tyre due to their status as colonia. In addition, within each assemblage females generally exhibited higher caries (and associated periapical cavities and ante-mortem tooth loss) than males. Although dental caries may be linked to nondietary factors, these patterns may support a more cariogenic diet for females in agreement with literary accounts reciting gender-based divisions in Roman society, at least to the extent that these would manifest in dietary patterns. The findings from this study offer important insights into major and understudied communities along the Phoenician coast. Yet, further research is required, employing complementary methods (e.g., isotopic analysis and dental calculus microdebris) and including larger datasets of Roman Phoenician assemblages.

Automated summary

This bioarchaeological study examines dental disease and dietary patterns in Roman Phoenicia's coastal areas, specifically Byblos, Beirut, and Tyre. Byblos showed higher rates of dental diseases and wear compared to Beirut and Tyre, suggesting a higher consumption of carbohydrates but also poorer oral hygiene and greater mechanical stress. This difference may be related to the economic and political status of these cities. Females in all sites generally had higher rates of dental caries, which may reflect gender-based dietary patterns in Roman society. The findings provide important insights into understudied Phoenician communities, but further research with larger datasets and complementary methods is needed.
