Dental Pathologies in the Three Kingdoms Period Population from Imdang Site, Gyeongsan, Korea / 체질인류학회지

ABSTRACT

Dental pathology has the potential to provide insight into the interpretation of the health and life style of past population. In particular, dental pathologies are strongly correlated to subsistence pattern, diet habits and food-preparation techniques. For this reason, my studies have focused on analyses of dental diseases (e.g., caries, abscesses, ante-mortem tooth loss, enamel hypoplasia, dental attrition, and periodontal diseases). The purpose of this study is to investigate the prevalence of dental pathologies of the Imdang population dating to between A.D. 3rd and A.D. 7th centuries (Three Kingdoms Period). In this study, through a macroscopic observation of dental remains from 138 individuals of the Imdang site, the prevalence of caries, abscess and ante-mortem tooth loss was examined. The association between sex, age and the frequencies of pathology was analyzed by the Chi-square tests. The results showed that the frequency of dental pathologies was consistently low level in Imdang population. Caries prevalence in the Imdang population was higher in females (6.15%) that in males (4.89). Among dental pathologies, abscess prevalence (0.7%) was lowest in Imdang population. Meanwhile, AMTL prevalence was 10.81% in males and 3.8% in females. There is a statistically significant difference between the anterior teeth of males and females (p<0.05). This study revealed that the rate of dental caries, abscess and AMTL in the Three Kingdoms Period population was relatively low level. This study is the first report of the patterns of dental pathologies in the Three Kingdoms Period population. It is necessary to investigate more number of pathologic markers that needed for deeper understanding of the multi-faceted nature of dental pathologies of ancient populations.
