Intentional Dental Modification and Oral-Dental Health in Western Micronesia
Intentional dental modification was observed in Pre-Latte and Latte Period bioarchaeological samples from western Micronesia. These purposeful cultural alterations include multilinear incisions and horizontal abrading of labial tooth surfaces in the Mariana Islands and tooth blackening in Palau. To understand the biological impacts of intentional modification, over ten pre-European Contact (before AD 1521) dental samples from the Mariana Islands were examined to test for a correlation between intentionally modified teeth and two indicators of oral-dental health: caries and periapical abscesses. Although differences in data collection methods and poor bone preservation prevented the use of both indicators across the board, preliminary results indicate that horizontal abrading in at least one sample appears to be associated with carious lesions while dental incising is not.
