七四级工农兵学员在下乡开门办学过程中,发现所在公社龋齿的发病率很高,他们“急贫下中农之所急,痛贫下中农之所痛”,在老师的指导下,积极对该地龋齿患病情况进行了调查,发现青少年儿童中患龋率高达55.7％,有的大队还高达77.6％。 为什么当地龋齿患病率那么高?为什么同一个公社患龋率还有不同,他们又对当地井水中的含氟量进行了测定,结果证明当地井水含氟量低;患龋率最高的大队,含氟量也最低。说明长期饮用低氟水可能是青少年儿童患龋率较高的原因之一。目前在他们的建议下,当地行政与卫生部门正大力开展龋齿预防工作,商业部门组织供应氟化牙膏,保护劳动力,保护青少年儿童的身体健康。
During their schooling in the countryside, the workers, peasants and soldiers of the prefectural and agricultural levels found that there was a high incidence of dental caries in the communes. They were “anxiously needed by the peasants in the middle of the poor, and painful by the middle peasants.” Under the guidance of the teacher, The prevalence of dental caries was investigated and found that caries prevalence in young children as high as 55.7%, and some brigade up to 77.6%. Why the prevalence of caries in the local area is so high? Why is there a difference in caries prevalence in the same commune? They also measured the amount of fluoride in well water in the local area. As a result, the fluorine content of well water in the local area was low, and the brigade with the highest caries rate , The lowest fluorine content. The long-term consumption of low-fluoride water may be one of the reasons for the higher prevalence of caries in adolescents and children. At present, at their suggestion, the local administrative and health departments are vigorously implementing prevention of dental caries. The commercial departments organize the supply of fluoride toothpaste, protect the labor force and protect the health of children and adolescents.
