摘　　要：目的调查距今六千年左右新石器时期古人牙齿的龋病状况,以探求龋病的发生发展趋势。方法观察记录并统计了西安半坡博物馆馆藏73例人头颅骨全部牙齿的龋病情况,用SPSS12.0软件对913颗牙齿进行统计学分析。结果当时人群患龋率为26.03%,龋齿率为2.85%,总龋均为0.35。从龋患在牙面上的分布看,当时人群的牙合面龋最多,占全部龋患的73.08%,其次为邻面龋,占50.00%。不同牙位龋患发生的多少顺序为M2>M3>M1>P2,第二磨牙的患龋率最高;龋病罹患在性别上无显著性差异。结论新石器时代半坡人的龋病发病较现代人低,随着物质文明的发展人类的龋患率不断增高。Objective：To investigate the status of dental caries in human of the Neolithic Age. Methods：913 teeth in 73 human cranial bones of the Neolithic Age kept in Banpo museum were examined ,the soft ware SPSS 12.0 was used for statistics. Resultes：Caries was found in 19 out of the 73 subjects, the dental caries prevalence rate was 26.03%. There were 26 caries teeth, which was 2.85% of the whole teeth. The mean DMFT of the 73 objects was 0.35. The second molars had the highest pereentage（38.46% ） of caries. There was no significant difference between male and famale（ P 〉 0.05 ）. The occlusal caries （ 73.08% ） was more than the interproximal （ 50.00% ）. Conclusion： The prevalence of dental caries in the people at the Neolithic Age was lower than that in modern people.
