1986年我们调查了氟病区偃师县台沟村和对照区十八里河、河医大子弟学校共1649名7～17岁中小学生斑釉和龋病的发病率,同时测定这些地区的总摄氟量,并对这两种牙病与总摄氟量的关系进行了探讨。调查结果氟病区总摄氟量5.433mg/日,斑釉率94.35%,患龋率13.6%:而对照区总摄氟量和斑釉率均低,于前者,患龋率高于前者。结果表明斑釉率与总摄氟量成正比关系,患龋率与总摄氟量成反比关系。
In 1986, we investigated the incidence of spot glaze and dental caries in 1649 primary and secondary school students aged 17-17 years in Taigou Village and Control District of Talihali River and Hexi Medical University in Yanshi County of the Fluorosis Area, and determined the total Fluoride intake, and the relationship between these two dental diseases and total fluoride exposure were discussed. Survey results fluorine fluoride total amount of fluorine 5.433mg / day, spot glaze rate 94.35%, caries prevalence rate of 13.6%: the control area total fluoride exposure and spot glaze rate are low, in the former, prevalence of caries was higher than the former. The results show that the rate of spot glaze and total fluorine is proportional to the relationship between the caries prevalence rate and the total amount of fluorine is inversely proportional relationship.
