在伟大领袖毛主席关于“预防为主”的方针指引下,广州市从1965年下半年开始全面实行供水(自来水)氟化防龋的保健措施。供水氟化六年,广州市芳村地区减少了儿童的龋齿50％左右(见广州《新医学》1972年第二期第20页)。本文系报告广州市东山地区的防龋效果。本地区的供水氟化处理方法,基本上是与芳村地区相同,规定的含氟量平均为0.8PPM.(夏天为0.6～0.8PPM,冬天为0.8～1.0PPM)。我们结合日常的学校防治工作,在1966年上半年(即氟化初期)对本地区的所有小学和部分中学的学生进行了口腔检查和纪录。检查系用口镜和探针,在良好光线下进行。今年上半年我们又对部分学校进行了复
Guided by Chairman Mao’s principle of “prevention first”, the great leader, Guangzhou Municipality fully implemented the fluoridation and anticorrosion health care measures for water supply (tap water) from the second half of 1965. Fluoridation of water for six years, Guangzhou Fangcun area to reduce children’s dental caries about 50% (see Guangzhou “new medicine” 1972 second period p. 20). This article reports the prevention of caries in Dongshan, Guangzhou. Fluoridation of water supply in this area is basically the same as in Fangcun, with an average fluorine content of 0.8 PPM (0.6 to 0.8 PPM in summer and 0.8 to 1.0 PPM in winter). Combining our day-to-day school control efforts, we conducted oral exams and records of all elementary and middle school students in our region during the first half of 1966 (early stage of fluorination). Department of inspection with a mirror and probe, in good light. In the first half of this year, we reworked some of the schools
