Linear Enamel Hypoplasias in Hasanlu: a Survey

The purpose of this thesis was to investigate the presence of LEH in the Hasanlu and Dinkha Tepe collection, compare the LEH presence between the two collections and between the two areas of the Hasanlu site, High Mound and Lower Mound. The overall questions to be answered were what linear enamel hypoplasia prevalence exists, if there was a difference in linear enamel hypoplasia prevalence between sites and if that difference was significant enough to signal phenomena that shapes systemic health status. Every tooth to each individual in the collection was macroscopically surveyed to look for the presence of linear enamel hypoplasia. If present the LEH lines were measured with a Mitutyo needle nosed caliper and recorded. Only teeth with matching LEH were said to have LEH. The LEH prevalence was found to be 54.2% in High Mound Period IVB, 68.9% in Lower Mound, 80% in High Mound Period IIIl, 59.4% in Dinkha Tepe, and 64% overall. The significance of the LEH numbers was determined with a chi-square test, and it was found that there was no statistically significant difference between sites. Statistical significance was found for the Lower Mound age and sex distribution.
