鲤鱼墩遗址出土人牙的牙齿磨耗和龋齿

距今约6000年以前, 华南先民以渔猎采集经济为主, 并辅之以块茎植物种植的观点已为学界所共识。这种类型的生业方式与长江中下游、华北及其以北地区有着较大的区别。这不仅反映在遗址出土的动植物遗存和生产工具的不同, 也体现在出土人骨体质特征的差异上。后者已初步为C、N稳定同位素的比较研究所证实。本文则利用鲤鱼墩遗址出土的人牙,从牙齿磨耗和龋齿两方面考察上述差异。

Study of Tooth Wear and Caries of Teeth Unearthed from the Liyudun Site

The idea that 6000 BP inhabitants in southern China made their living mostly by fishing, hunting and gathering, with planting roots and tubers as supplement has been widely accepted. This type of subsistence strategy was different from that that occurred in the middle and lower valley of Yangtze River and in northern China. The differences were not only presented in the remains of animals, plants, and tools excavated from archaeological sites, but also expressed by physical features of unearthed human bones. The latter evidence was analyzed using carbon and nitrogen stable isotopes. Using teeth uncovered from the Liyudun site, we attempted to exam the differences mentioned above on tooth wear and caries.
