新疆生产建设兵团南疆垦区3~5岁儿童龋病流行病学调查分析

Epidemiological Investigation and Analysis of Dental Caries among Children Aged 3-5 Years in Southern Reclamation Area of Xinjiang Production and Construction Corps

目的:调查新疆生产建设兵团南疆垦区学龄前(年龄范围3~5岁)儿童乳牙患龋状况,为制定学龄前儿童口腔健康策略和改善儿童患龋状况工作的开展提供理论依据。方法:采用分层整群抽样的方法,对南疆垦区10所幼儿园1159名学龄前儿童(3~5岁)进行口腔临床检查,分析比较不同年龄、性别、民族、城乡学龄前儿童的龋病率和龋齿充填率等差异。结果:受检幼儿中,有884名幼儿患龋,患龋率为76.27%,龋均为4.39,龋齿充填率为1.64%,98.36%的龋坏未经治疗。不同年龄段的儿童患龋率差异有统计学意义(P<0.05),儿童患龋率和龋均随年龄增长而增加(P<0.05);维吾尔族儿童乳牙的患龋率高于汉族儿童,差异具有统计学意义(P<0.05);团场儿童乳牙的患龋率高于城市儿童,差异具有统计学意义(P<0.05);性别因素与儿童乳牙患病率无明显关联;乳牙的龋均在不同性别、民族、城乡学龄前儿童之间差异无统计学意义。龋齿充填率在维、汉不同民族、年龄组和城乡之间差异有统计学意义(P<0.05)。患龋牙以乳切牙和乳磨牙最多见,左右两侧患龋风险性较为一致,下颌乳牙龋齿呈U分布,上颌乳牙龋齿分布呈现W分布。结论:新疆生产建设兵团南疆垦区3~5岁学龄前儿童乳牙患龋情况仍处于较高水平,应从各个方面入手强化干预措施,有效控制儿童乳牙龋病的发展。

Objective:To investigate the caries status of preschool children(age range 3~5 years old)in southern reclamation area of Xinjiang Production and Construction Corps,and provide theoretical basis for the formulation of oral health strategies for preschool children and the improvement of caries status in children.Methods:Using stratified,cluster sampling,Clinical oral examination of 1159 preschool children(3~5 years old)in 5 kindergartens under reclamation area of Southern Xinjiang.To analyze and compare the caries rate and caries filling rate of preschool children of different age,sex and nationality,urban and rural areas.Results:Of the children tested,there are 884 children suffering from caries.The caries rate was 76.27%,The caries were 4.39,The caries filling rate was 1.64%,98.36%of caries are untreated.There were statistically significant differences in caries rates among children of different ages,the caries rate and caries increased with age(P<0.05).The caries rate of Uighur children increased with age(P<0.05),the caries rate was higher than that of Han children(P<0.05).The caries rate of Uighur children was higher than that of Han children(P<0.05).The caries rate of children in Tuanchang was higher than that of urban children(P<0.05).There was no significant difference between sex factors and the prevalence of deciduous teeth in children,and there was no significant difference between preschool children of different sex,nationality,urban and rural areas.Dental caries are common in deciduous incisors and abrasions.The risk of caries on both sides is consistent,Dental caries of mandibular deciduous teeth are U distributed.Dental caries distribution of maxillary deciduous teeth showed W distribution.Conclusion:Caries of 3~5 year old preschool children in southern reclamation area of Xinjiang Production and Construction Corps are still at a high level.The intervention should be strengthened in all its aspects,effectively control the development of dental caries in children.
