【摘要】：目的了解西安市城乡7~9岁儿童第一恒磨牙萌出与患龋状况,为开展儿童口腔保健工作提供依据。方法对西安市新城和户县15 513名7~9岁儿童,按照统一检查标准,调查第一恒磨牙萌出与患龋情况。结果 7~9岁儿童第一恒磨牙完全萌出率为93.3%,7,8,9岁组分别为86.6%,95.0%,97.7%,差异有统计学意义(χ2=1 921.93,P0.01)。第一恒磨牙总患龋率为9.6%。第一恒磨牙患龋率性别、年龄、城乡儿童间差异均有统计学意义;第一恒磨牙龋失补牙数随年龄增长而增加,女童高于男童;龋补充填率随年龄增长而增加,城市高于农村(P值均0.01)。下颌第一恒磨牙为龋病的好发牙位,占68.2%。牙合面、颊面患龋最多见,分别占总患龋牙面数的83.2%和12.7%。龋齿补填率随年龄增长而增加,7~9岁分别为5.2%,7.9%,10.4%(P0.01);城市儿童龋补充填率高于乡村,分别为10.8%和5.2%(P0.01)。结论西安市7~9岁儿童第一恒磨牙患龋状况与全国其他省市较为接近,应重点封闭下颌第一恒磨牙和牙面的牙合面、颊面。
[Abstract]:Objective to investigate the first permanent molar eruption and caries in 7-9-year-old children in urban and rural areas of Xi'an, in order to provide basis for oral health care of children. Methods the first permanent molar eruption and caries were investigated in 15 513 7-9-year-old children in Xincheng and Huxian, Xi'an city according to the standard of unified examination. Results the complete eruption rate of the first permanent molar was 93.3% in 7-9-year-old children, 86.6%, 95.0% and 97.7% in 7,8-year-old and 9-year-old children, respectively. There was significant difference between them (蠂 2 / 1 921.93, P0.01). The total incidence of caries in the first permanent molar was 9.6%. There were significant differences in the rate of first permanent molars caries, age and children between urban and rural areas, and the number of caries lost in the first permanent molars increased with the increase of age, and the number of caries lost in girls was higher than that in boys. The rate of filling caries increased with the increase of age, which was higher in city than in rural area (P < 0.01). The mandibular first permanent molar is the most common dental caries, accounting for 68.2%. The most common caries were occlusal surface and buccal surface, accounting for 83.2% and 12.7% of the total caries surface, respectively. The filling rate of caries increased with age (5.2%, 7.9%, 10.4% respectively at 7-9 years old), and was 10.8% and 5.2% (P0.01) in urban children, which was higher than that in rural areas (10.8% and 5.2%, respectively). Conclusion the caries status of the first permanent molars in children aged 7 ~ 9 years old in Xi'an is close to that of other provinces and cities in China. The occlusal and buccal surfaces of the mandibular first permanent molars and the occlusal surfaces should be closed with emphasis.
