甘肃临潭磨沟墓地人骨的牙齿健康状况

Dental Health of Ancient Mogou Residents in Lintan, Gansu Province

本文通过甘肃临潭磨沟齐家文化墓地出土的262例人骨标本的牙病情况尤其是龋病、牙周病、根尖周病以及牙结石情况的统计与分析,得知磨沟墓地古代居民牙齿疾病的基本情况:1)牙病的罹患率性别差异显著,女性龋病和根尖周病的罹患率高于男性,而在牙周病和牙结石的出现率上则是男性高于女性;2)牙病的罹患率随着年龄增长而增高;3)龋病、牙周病及根尖周病多发于臼齿,牙结石多发于门齿;4)重度磨耗牙齿多发牙周病及根尖周病;5)牙病罹患率不仅受到性别、年龄、牙位以及齿冠磨耗程度的影响,而且与磨沟组古代居民农业种植食物和采集食物并重的食物结构有关。

A total of 262 skulls from the Mogou cemetery of the Qijia Culture in Lintan County, Gansu Province, were examined for the incidence of observable dental diseases, including dental caries, periodontal disease, periapical disease and dental calculus. The results of statistical analysis indicate the following patterns： 1） Significant difference of dental diseases rates found between males and females, with females having higher rates of dental caries and periodontal disease, and males having higher rates ofperiapical disease and dental calculus. 2） Dental disease rate was positively correlated with age. 3） There was a higher prevalence of caries, periodontal disease, periapical disease in molars, and dental calculus in anterior teeth. 4） Severely attritted teeth had higher prevalence of periodontal and periapical diseases. 5） The prevalence of dental diseases is also associated with the mode of subsistence and diet, specifically farming and gathering.
