Objective To investigate the oral health status and awareness of urban children in Lhasa,aiming to provide a data basis for the prevention and treatment of children's caries and the promotion of oral health education. Methods A total of 504 Tibetan students were selected by cluster sampling from 2 primary schools in Chengguan District of Lhasa.All the participants were required to take oral health examination and complete a questionnaire about oral health awareness and behavior. Results The caries prevalence rate and mean decayed-missing-filled tooth(DMFT)of permanent teeth were 75.00% and 2.18±1.91,respectively.The rates of pit and fissure sealant and filling of permanent teeth were 3.77% and 6.81%,respectively.The caries prevalence rate of first permanent molars was 47.62%.The mean DMFT of permanent teeth and caries prevalence rate of first permanent molar were significantly higher in female group(=0.001 and =0.007,respectively).The prevalence rate of dental fluorosis was 61.51%,and the detection rate of dental calculus was 71.83%.Multivariate logistic regression analysis showed that prevalence of caries was influenced by many independent factors including gender,oral health awareness,intention of dental intervention,and dental experience. Conclusion High caries prevalence rate,low filling rate,and poor oral hygiene and health awareness were found among the primary school students in Lhasa,which require continuous dentistry investment and oral health education for the local students and their parents.
目的 调查拉萨市城区儿童口腔健康状况及认知水平，为儿童龋病防治及口腔健康教育推广提供数据依据。方法 采用整群抽样法从拉萨市城关区2所小学选取504名藏族学生。所有参与者均需进行口腔健康检查，并完成一份关于口腔健康认知与行为的问卷。结果 恒牙龋患率和龋失补牙面均数（DMFT）分别为75.00%和2.18±1.91。恒牙窝沟封闭率和充填率分别为3.77%和6.81%。第一恒磨牙龋患率为47.62%。女性组恒牙平均DMFT及第一恒磨牙龋患率均显著高于男性组（分别为P=0.001和P=0.007）。氟斑牙患病率为61.51%，牙结石检出率为71.83%。多因素logistic回归分析显示，龋病患病率受性别、口腔健康认知、口腔干预意愿及看牙经历等多种独立因素影响。结论 拉萨市小学生龋患率高、充填率低，口腔卫生及健康认知较差，需持续加大对当地学生及其家长的口腔医疗投入及开展口腔健康教育。
