【摘要】：目的了解广州市中小学生乳牙龋牙数及龋补与恒牙龋的关联性,为预防学生恒牙龋病提供参考。方法2014年9—12月,对广州市7,9,12和14岁的5 272名中小学生进行口腔检查,记录乳、恒牙患龋及龋补情况,运用负二项回归模型分析乳牙龋牙数和龋补数对恒龋牙数的影响。结果广州市7,9和12岁学生乳牙患龋率分别为48.24%,45.21%,6.10%。7,9,12和14岁学生恒牙患龋率分别为0.61%,2.85%,10.14%,14.28%。男、女生乳牙患龋率分别为35.04%和34.08%,恒牙龋患率分别为4.88%和8.82%。以恒龋数为结局变量,分析乳龋对恒龋的影响,调整学生年龄、性别和城乡后,负二项回归模型中离散参数的估计值为16.37(95%CI=9.27~28.90),女生较男生更易患恒牙龋,越年长的学生患恒牙龋的强度越高,且均有统计学意义(χ~2值分别为41.09,13.32,19.40,P值均0.01)。乳牙龋拟合负二项回归模型显示,调整年龄、性别和城乡后,有乳牙龋补和恒牙龋补的学生与恒牙龋的关联均有统计学意义(β值分别为1.00,2.76,P值均0.05)。将乳牙龋补和恒牙龋补同时纳入模型后,乳牙龋补对恒牙龋有保护效应(β=-1.09,95%CI=-1.72~-0.46,P0.01),而恒牙龋补和恒牙龋的正关联也仍有统计学意义(β=3.02,95%CI=2.65~3.39,P0.01)。结论乳牙龋越严重的中小学生恒牙龋也越严重,对乳牙龋进行龋补修复有助于降低恒牙龋牙数。
[Abstract]:Objective to investigate the correlation between caries and dental caries in primary and middle school students in Guangzhou, and to provide reference for the prevention of dental caries. Methods from September to December 2014, 5 272 primary and middle school students aged from 7 to 12 and 14 years old in Guangzhou were examined by oral examination to record the incidence of caries and dental caries in permanent teeth. The negative binomial regression model was used to analyze the influence of the number of caries and the number of dental caries on the number of permanent caries. Results the caries rates of primary teeth of students aged 7 and 12 in Guangzhou were 48.24 and 45.21, respectively. The caries rates of permanent teeth of students aged 14 and 14 were 0.612.85 and 10.1414.28, respectively. The caries rates of male and female deciduous teeth were 35.04% and 34.08%, respectively, and the rates of permanent teeth caries were 4.88% and 8.82%, respectively. The effect of breast caries on permanent caries was analyzed. After adjusting the age, sex and urban and rural areas of students, the estimated value of discrete parameters in negative binomial regression model was 16.3795% CI9.27 ~ 28.90%. Girls were more likely to suffer from permanent tooth caries than boys. The intensity of permanent tooth caries in the older students was higher, and there was statistical significance (蠂 ~ 2 = 41.09 ~ 13.32 ~ 19.40 P = 0.01). The negative binomial regression model of deciduous caries showed that after adjusting for age, sex and urban and rural areas, there was a significant correlation between primary caries and permanent dental caries (尾 = 1.00, 2.76, P = 0.05, respectively). After both primary and permanent dental caries were included in the model, primary dental caries had a protective effect on permanent dental caries (尾 -1.09 ~ 95CI-1.72 ~ -0.46% P 0.01), and the positive correlation between permanent tooth caries and permanent tooth caries was still statistically significant (尾 -1.099 ~ (95) CI 2.65 ~ 3.39 ~ (9) P 0.01). Conclusion the more serious the caries of primary and middle school students, the more serious the permanent teeth caries are, and the repair of caries is helpful to reduce the number of permanent teeth caries.
