Statistical analysis of 3,576 DMFT counts from three million observations of children aged 6 to 16 in East Germany shows a strong time-lagged relationship with fluoridation activities. More significant results, however, are found due to age and a score of socioeconomic factors. Additionally, caries prevalence decreases with time. Conversely, DMFT is not affected by size or type of dental staff, neither absolutely nor relatively.
对东德6至16岁儿童的三百万次观察中得到的3576个龋失补指数(DMFT)计数进行统计分析,结果显示其与氟化活动存在很强的时间滞后关系。然而,由于年龄和一系列社会经济因素,发现了更显著的结果。此外,龋齿患病率随时间下降。相反,龋失补指数(DMFT)绝对或相对而言都不受牙科工作人员规模或类型的影响。
