【摘要】：目的了解西安市3~7岁儿童乳牙患龋现况,为有效防控儿童乳牙龋齿奠定科学基础。方法本研究采用整群抽样方法,抽取西安市城区内45所幼儿园内的12 005名儿童进行口腔健康检查,并调查儿童的一般人口学特征。结果西安市3~7岁儿童乳牙患龋率、龋均和充填率分别为55.80%、2.45和8.14%,男女儿童乳牙患龋率和乳牙龋均之间差异无统计学意义,3~7岁年龄组儿童乳牙患龋率分别为45.22%、55.89%、61.81%和65.37%,乳牙龋均分别为1.69、2.46、2.87和3.12,乳牙充填率分别为3.08%、7.04%、10.29%和13.45%。儿童乳牙患龋率、龋均和充填率均有跟随儿童年龄增加而逐年增加的趋向。左右同名牙位患龋率明显对称,患龋率最高的是上颌双侧乳中切牙,其次为双侧下颌第二乳磨牙。结论西安市3~7岁儿童乳牙患龋率仍然处于较高水平,应加大口腔健康教育力度,尽早采取有效干预措施,降低乳牙龋病对儿童健康的损害。
[Abstract]:Objective to investigate the prevalence of caries in children aged 3 to 7 years old in Xi'an, and to lay a scientific foundation for the prevention and control of caries in children. Methods using cluster sampling method, 12 005 children in 45 kindergartens in Xi'an city were selected for oral health examination, and the general demographic characteristics of children were investigated. Results the caries rate of children aged 3 years old and 7 years old in Xi'an city was analyzed. The caries mean and filling rates were 55.80 and 8.14, respectively. There was no significant difference in caries and caries of primary teeth between male and female children aged 37 years. The caries rate of primary teeth in the age group of 35.22 years was 45.229.89% and 61.81%, respectively. The caries of primary teeth were 1.692.462.87 and 3.12, respectively. The filling rates of primary teeth were 3.087.047.0410.29% and 13.4545 respectively. The incidence of caries, average caries and filling rates of children with primary teeth increased year by year with the increase of children's age. The caries rate of left and right teeth with the same name was significantly symmetrical, and the incidence of caries was the highest in the maxillary bilateral central deciduous incisors, followed by the bilateral mandibular second primary molars. Conclusion the dental caries rate of children aged 3 to 7 years old in Xi'an is still at a high level. Oral health education should be strengthened and effective intervention measures should be taken as soon as possible to reduce the damage to children's health caused by caries of deciduous teeth.
