目的:调查距今2200年前西安秦人的龋病状况,以探求龋病的罹患率及发展趋势。方法:观察记录并统计了西安高陵坡底遗址出土的111例古人的龋齿情况,用SPSS21.0软件对全部的1633枚牙齿进行统计学分析。结果:坡底人群患龋率为33.33%,其中男性患龋率为36.67%,女性患龋率为27.91%;龋齿率为3.12%,龋均为1.38。结论:龋病的罹患率与年龄具有相关性,壮年和中年为龋病的高发期,患龋率分别为46.30%和45.00%,龋齿率分别为4.64%和4.71%;患龋牙位发病率依次为M2〉M3〉M1〉M2〉M3〉M1〉P2〉P1〉C1〉P1〉P2;下颌龋齿罹患率高于上颌(3.32%〉2.89%),从龋患部位来看,邻面龋发病率最高(66.67%),其次为唇颊面龋(17.65%)和咬合面龋(13.73%),舌腭面龋最低(1.96%)。
Objective:To survey the caries conditions of Qin people lived in late Warring States Period and to search the attack rate and growing trend of caries.Methods:The decayed teeth of 111 ancients unearthed at Podi site of Gaoling,Xi'an were observed,recorded and counted.A total of 1633 teeth were counted by statistical analysis technique via SPSS 21.0.Results:Prevalence rate of Podi people was 33.33%,of which males' prevalence rate was36.67% and female's was 27.91%.Dental caries rate was 3.12% and total DMFT was 1.38.Conclusion:Attack rate of caries is correlated with age.Prime and middle age are high-incidence season of caries.Prevalence rate of primary-age group is 46.30%,and the middle age group is 45.00%.Dental caries rate of primary-age group is4.64% and the middle age group is 4.71%.The morbidity of caries for different teeth is M2〉M3〉M1〉M2〉M3〉M1〉P2〉P1〉C1〉P1〉P2.Caries attack rate of lower jaw is higher than that of upper jaw(3.32%〉2.89%).From the aspect of attack location,proximal caries has the highest morbidity(66.67%),then buccal labial surface caries(17.65%)and occlusal surface caries(13.73%),and tongue palatal surfaces caries has the lowest morbidity(1.96%).
