陕西陇县两千年前人牙槽骨水平吸收状况的研究

目的：调查距今2000年前人牙槽骨水平吸收的状况。方法：观察并统计陕西陇县出土的59具人骨架全部832个牙齿的牙槽骨水平吸收的情况。分别对牙槽骨水平吸收的患病率、罹患的牙位进行了统计分析。结果：该人群牙槽骨水平吸收的平均患病率为77．97％。不同牙位牙槽骨水平吸收的发生率高低顺序为：第一磨牙〉第二磨牙=第二前磨牙〉第一前磨牙〉第三磨牙〉尖牙〉侧切牙〉中切牙。结论：在2000年前的人群中可能广泛存在牙槽骨的水平吸收。

The resorption of alveolar bones from the Long coanty in Shanxi Province about 2,000 years ago

AIM:To investigate the resorption of alveolar bones about 2,000years ago. METHODS: Eight humdred and thirty-five teeth of 59 skulls excavated from the Long county in Shanxi Province were checked. The prevalence rate and the tooth position of the resorption of alveolar bones were analysed. RESULTS: The prevalence rate of the resorption of alveolar bones in different tooth position was first molar>second molar=second premolar>first premolar>third molar>cahine>lateral incisor >central incisor. CONCLUSION: The resorption of alveolar bones was common 2,000years ago.
