A water fluoridation program launched in the United States in 1945 has become a worldwide application for caries prevention. Although such a program is important in Japan, water fluoridation in large communities has not been established. This study aimed to develop safe small-scale water fluoride equipment that can be easily used to carry out water fluoridation programs in areas with children in long-term care facilities, and in developing countries without water supply facilities.
Batch-type NaF addition adjustment equipment was manufactured as small-scale water fluoride equipment. The fluoride concentration of the adjusted water with this equipment was measured using an ion meter and a fluoride composite electrode. All 51 water quality standards set by the Ministry of Health, Labour, and Welfare of Japan were tested.
The fluoride ion concentration of the adjusted water was 0.7 mg/L and it was constant and stable. The adjusted water conformed to the water quality standard values of the Japanese Water Supply Law.
Water produced with small-scale water fluoridation equipment had a fluoride concentration of 0.7 mg/L, which is the recommended concentration for caries prevention. The fluoride concentration was stable.
1945 年在美国启动的水氟化项目已成为全球范围内预防龋齿的应用。尽管该项目在日本很重要，但大型社区的水氟化尚未建立。本研究旨在开发安全的小型水氟化物设备，以便在长期护理设施中有儿童的地区和没有供水设施的发展中国家，轻松开展水氟化项目。
制造批处理型 NaF 添加调整设备作为小型水氟化物设备。使用离子计和氟复合电极测量该设备调整后的水的氟化物浓度。测试了日本厚生劳动省设定的所有 51 项水质标准。
调整后的水的氟离子浓度为 0.7mg/L，且保持恒定稳定。调整后的水符合日本《水道法》的水质标准值。
小型水氟化设备生产的水的氟化物浓度为 0.7mg/L，这是预防龋齿的推荐浓度。氟化物浓度稳定。
