Abstract Details

2021, Master of Arts, Ohio State University, Anthropology.
Accentuated Striae (AS) are enamel growth disruptions visible as thick dark lines in histological slides of enamel, paralleling normal growth lines known as brown striae of Retzius. They have been used as indicators of stress in archaeological, forensic, and primate studies within the field of biological anthropology. This research investigates whether there is a relationship between the manifestation of AS and (1) socioeconomic status (SES) differences between two Ohio populations, and (2) several physiological attributes of the sample. Deciduous teeth were collected from 48 individuals representing two populations with known disparities in overall stress exposure (high-SES sample from affluent neighborhoods in Central Ohio; low-SES sample from primarily rural Appalachian Ohio). Histological slides of enamel were created, and the presence of AS was observed in each tooth using a Nikon polarizing transmitted light microscope with Cannon digital camera. AS prevalence was compared between samples and contrasted with several demographic and physiological health measures (gestation length, birth mode, sex of infant, gestational diabetes). AS were observed among the low-SES sample (31%), but not among the high-SES sample (0%) (chi-square test; p=0.007). There are no associations between AS and any other assessed measure (p>0.05 for all comparisons). These results support the hypothesis that AS and non-specific population stress are related, thereby reinforcing AS as a valid indicator for reconstructing past population health
