目的了解2015年深圳在校小学生龋病流行特征,为制定小学生口腔健康策略和开展口腔健康促进提供依据。方法对深圳市公立小学169 918名在校学生进行口腔健康普查。通过深圳市学生口腔防治管理系统收集数据。结果 2015年深圳市小学生乳牙患龋率为49.5%,填充率为13.6%,龋均为(1.81±2.52),缺失率为4.6%;恒牙患龋率为16.4%,填充率为20.4%,龋均为(0.33±0.88),恒牙缺失率为0.2%,显著龋病指数(Si C)为(0.98±1.27)。随着年龄增长乳牙患龋率及龋均呈下降趋势,恒牙患龋率及龋均呈上升趋势。12岁儿童恒牙患龋率为26.5%,龋均为(0.57±1.15),缺失率为0.4%,Si C为(1.72±1.42)。女生恒牙患龋率(18.5%)高于男生(14.8%)(χ~2=431.38,P<0.01);女生恒牙龋均(0.38±0.94)也高于男生(0.29±0.82)(t=-20.84,P<0.01)。原关外小学生的乳、恒牙患龋率(55.0%,18.3%)均高于原关内(46.0%,15.2%)(χ~2值分别为1 289.04,294.90,P值均<0.05),龋均(2.14±2.66,0.39±0.98)也高于原关内(1.61±2.40,0.29±0.80)(t值分别为-41.04,-23.26,P值均<0.01)。结论深圳小学生龋病流行处于较低水平,原关外新区情况尤为严重。需要重点加强口腔健康教育及干预措施。
Objective To understand the prevalence of dental caries among primary school students in Shenzhen in 2015 and to provide evidence for the development of oral health strategies for primary school children and oral health promotion. Methods A total of 169 918 undergraduates from Shenzhen Public Primary School were surveyed. Through the Shenzhen City student oral management system to collect data. Results The prevalence of dental caries was 49.5% in primary school students in Shenzhen in 2015, the filling rate was 13.6%, the caries was 1.81 ± 2.52, the rate of caries was 4.6%, the rate of caries was 16.4%, the rate of filling was 20.4% The caries was (0.33 ± 0.88), the permanent tooth loss rate was 0.2%, and the significant cariousness index (Si C) was (0.98 ± 1.27). With age, caries prevalence and caries in deciduous teeth showed a decreasing trend, and the caries prevalence and caries in permanent teeth showed an upward trend. The caries prevalence rate of permanent 12-year-old children was 26.5%, caries was (0.57 ± 1.15), the missing rate was 0.4%, Si C was (1.72 ± 1.42). The prevalence of dental caries was higher in girls than in boys (18.5% vs. 14.8%, χ ~ 2 = 431.38, P <0.01) = -20.84, P <0.01). The caries prevalence of primary and secondary primary school students was 55.0% and 18.3% respectively, higher than that of primary school (46.0%, 15.2%) (χ ~ 2 = 1 289.04 and 294.90 respectively, P <0.05) (2.14 ± 2.66,0.39 ± 0.98) were also higher than the original (1.61 ± 2.40,0.29 ± 0.80) (t values were -41.04, -23.26, P values were <0.01). Conclusion The caries prevalence among primary school students in Shenzhen is at a low level, especially in the newly opened area. Need to focus on oral health education and interventions.
