The aim of this study was to evaluate the operational control of water fluoridation at the city water supply plant in Niterói, Rio de Janeiro, Brazil, from January to December 2000. The water treatment supervisor filled out a questionnaire on the control of water fluoridation. In addition, water samples were collected every two weeks for fluoride analysis before and after treatment. Samples were analyzed by an independent laboratory using an ion-specific electrode. According to the water treatment supervisor, the entire process for controlling fluoride concentration in the water was rigorous and complied with Brazilian guidelines, but according to testing, 96% of samples were inadequate in terms of risks/benefits of fluoride use from water. The information obtained from the plant supervisor and the test data were thus mutually inconsistent. Based on these data, an independent water fluoride concentration control program is needed to ensure the benefits of dental caries prevention for the population.
本研究的目的是评估2000年1月至12月期间巴西里约热内卢尼泰罗伊市供水厂的水氟化操作控制情况。水处理主管填写了一份关于水氟化控制的问卷。此外，每两周采集一次处理前后的水样进行氟化物分析。样本由一家独立实验室使用离子特异性电极进行分析。根据水处理主管的说法，控制水中氟化物浓度的整个过程很严格，符合巴西的指导方针，但根据测试，96%的样本在水中使用氟化物的风险/益处方面不达标。因此，从工厂主管处获得的信息与测试数据相互矛盾。基于这些数据，需要一个独立的水氟化物浓度控制计划，以确保为民众预防龋齿带来益处。
