目的：本研究调查了居住在可忽略（NF: 0.2 ppm）、最佳（OPF: 1.0 ppm）和四倍最佳（4倍OPF: 4.0 ppm）水系统中天然氟化物含量社区的7-14岁儿童氟斑牙和龋齿的患病率。方法：对344名终身居住在社区的儿童进行调查。结果：无论是用氟斑牙牙面指数还是Dean's指数，4X OPF社区儿童氟斑牙患病率最高。虽然在OPF和NF社区中氟中毒的严重程度在外观上是轻微的，但结果表明氟中毒确实发生在最佳和可忽略的氟化社区。与NF社区相比，OPF社区的DMFT和DMFS得分分别低9.2%和21.2%。结论：在牙齿发育期间摄入含1 ppm或更少氟化物的水可能导致氟牙症，尽管其形式较轻。然而，在目前有许多含氟产品可供使用的情况下，与饮用氟化物含量可忽略不计的水的儿童相比，饮用含1 ppm氟化物的水的儿童继续获得龋齿保护。因此，发展相对较小的不美观状况的潜力必须与减少牙病的潜力相权衡。
Objectives:This study investigated the prevalence of dental fluorosis and caries in 7–14‐year‐old children residing in communities with negligible (NF: 0.2 ppm), optimal (OPF: 1.0 ppm), and four‐times optimal (4X OPF: 4.0 ppm) naturally occurring fluoride in their water systems.Methods: Examinations were performed on 344 children who were lifetime residents of their communities.Results: Whether using the tooth surface index of fluorosis or Dean's index, children examined in the 4X OPF community had the highest prevalence of dental fluorosis. While the severity of fluorosis seen in the OPF and NF communities was mild in appearance, the results indicate that fluorosis does occur in optimally and negligibly fluoridated communities. Compared to the NF community, DMFT and DMFS scores in the OPF community were 9.2 percent and 21.2 percent lower, respectively.Conclusions: The ingestion of water containing 1 ppm or less fluoride during the time of tooth development may result in dental fluorosis, albeit in its milder forms. However, in these times of numerous products containing fluoride being available, children ingesting water containing 1 ppm fluoride continue to derive caries protection compared to children ingesting water with negligible amounts of fluoride. Thus, the potential for developing a relatively minor unesthetic condition must be weighed against the potential for reducing dental disease.
