台湾大学医学院牙医学系与台湾省环境卫生院协同制定了一项龋齿预防规划,并选台湾中部的中兴新村为自来水氟化防龋实验研究区,毗邻的草屯镇为对照区,两地年平均气温为24℃,水含氟量中兴新村为0.07ppm,草屯镇为0.08ppm,1971年5月开始在中兴新村自来水厂加氟,氟化物浓度经常保持为0.6ppm,加氟前半年曾在两地作口腔检查作为日后复查
Department of Dentistry, College of Medicine, National Taiwan University, and Taiwan Provincial Environmental Hygiene Department co-developed a dental caries prevention program and selected Zhongxing New Village in central Taiwan as the Fluoride Caries Demonstration Area for running water fluoride. The adjacent Caotun Township is the control area. Both places The annual average temperature is 24 ℃. The water content of fluorine in Zhongxingxin Village is 0.07ppm and that of Caotun Town is 0.08ppm. Since May 1971, fluoride has been added to the water plant of Zhongxing New Village. The fluoride concentration is always kept at 0.6ppm. I have conducted oral examinations in both places for future review
