Water fluoridation has not been introduced in Norway, although 99% of the population receive water with suboptimal fluoride levels. Alternative methods of fluoride prophylaxis have gained wide acceptance in this country. While less than 1% of the children received fluoride tablet in 1971, sales data in 1976 indicated a daily supply of fluoride tablets to 50% of the 0-5-year-olds and to 20% of the 6-11-year-olds. Most schoolchildren have joined mass prophylactic programs with regular with regular applications of fluoride solutions. Furthermore, fluoride-containing dentifrices have become available and are increasingly used. The increased use of fluoride has been paralleled by a marked reduction in caries and restorative need. During the past 5 years, a reduction of about 45% in the number of fillings inserted in 6-17-year-old children has been noted. In some areas, a 70% reduction has been recorded. The ratio between expenses for prophylaxis and savings in cost of treatment is favorable. The Norwegian Adverse Drug Reaction Committe received 34 case reports of adverse effects ascribed to fluoride prophylaxis, from 1970 to 1977. None of the 25 follow-up studies performed, suggested fluoride to have been responsible for the reported symptoms. In Norway, the benefits of fluoride prophylaxis are becoming increasingly evident.
挪威尚未推行水氟化措施，尽管99%的人口所使用的水中氟化物含量未达最佳水平。在该国，其他预防氟化物的方法已被广泛接受。1971年，接受氟化物片剂的儿童不到1%，而1976年的销售数据显示，每天为50%的0至5岁儿童和20%的6至11岁儿童供应氟化物片剂。大多数小学生都参加了定期使用氟化物溶液的大规模预防项目。此外，含氟牙膏已可供使用且使用越来越广泛。氟化物使用的增加与龋齿和修复需求的显著减少同时出现。在过去5年中，已注意到6至17岁儿童所补牙洞的数量减少了约45%。在一些地区，记录到减少了70%。预防费用与治疗成本节省之间的比例是有利的。1970年至1977年期间，挪威药物不良反应委员会收到了34例归因于氟化物预防的不良反应病例报告。所进行的25项随访研究中，没有一项表明氟化物与所报告的症状有关。在挪威，氟化物预防的益处正变得越来越明显。
