郑州青台遗址新石器时代中晚期人群龋齿的统计与分析

本文通过对郑州青台遗址新石器时代中晚期91例个体、1913枚牙齿罹患龋齿的统计与分析可知,青台人群患龋率为71.43%,龋齿率为13.38%。其中,龋齿率女性高于男性,可能与女性孕期生理变化、食物选择及性别分工等有关。上颌龋齿率高于下颌,臼齿及咬合面为龋齿易患齿类及部位。通过对比可知青台人群显示出较高的龋齿罹患率,暗示该人群饮食中应包含较多的碳水化合物类食物,这可能与新石器时代中晚期黄河中游发达的旱作农业有关。此外,龋齿率在黄河及长江中、下游新石器时代农业人群中的区域性差异可能与龋病病因的复杂性和各地区不同的文化面貌、人群生活方式有关。

Analysis of dental caries in the Yangshao population at the Qingtai site,Zhengzhou city

This paper focuses on the prevalence of dental caries in the Neolithic Yangshao population from the Qingtai site, Zhengzhou city, Henan Province. A total of 1913 teeth and 91 individuals were included in this study. The individual caries rate of Qingtai group is 71.43%, and the caries rate of teeth is 13.38% which rises to 17.03% after correction. Females had a higher caries rate than males, which may be attributed to the physiological changes during pregnancy, food preference and labor division between different sex groups. The caries rate of maxilla is higher than that of mandible; besides, molars and occlusal surfaces were more prone to dental caries than other teeth and locations. Compared with other Neolithic populations in China, Qingtai people presented a relatively higher caries rate. This phenomenon suggests that their diet may contain a large amount of carbohydrates, which can also be associated with the developed millet farming in this region during the Yangshao culture period. In addition, the regional differences of dental caries rate among the Neolithic agricultural populations in the middle and lower reaches of the Yellow River and the Yangtze River may be related to the complexity of the caries etiology and the differences of cultural features as well as lifestyles.
