The caries experience of children aged six, eight, and ten years, examined in Perth after ten years of fluoridation was less than half that of children examined before fluoridation. In a concurrent survey, the caries experience of children examined in two unfluoridated towns was double that of the Perth children.
在珀斯,经过十年的氟化处理后,对6岁、8岁和10岁儿童进行检查发现,他们的龋齿发病率不到氟化处理前接受检查儿童的一半。在一项同期调查中,在两个未进行氟化处理的城镇接受检查的儿童的龋齿发病率是珀斯儿童的两倍。
