Under the conditions of an optimized (with regard to caries prevention) fluoride content of the drinking uater, the authors studied (in the framework of an oral hygiene measure covering 32 months) in 149 children 6.5-8 years of age the effects of supervised daily dental and oral care on dental health. The improvement in oral hygiene (OHI) by 33% is in harmony with an additional caries reduction by 33.3% (DMF/S index) and a decrease of the PM index by 47%. A wider use of oral hygiene actions as secondary preventive measures is, therefore, recommended also for towns with fluoridated drinking water.
在饮用水氟含量达到预防龋齿优化水平的条件下，作者对149名6.5至8岁儿童进行了一项为期32个月的口腔卫生措施研究，以观察在监督下每日进行牙齿和口腔护理对牙齿健康的影响。口腔卫生改善率（OHI）为33%，同时龋齿减少率（DMF/S指数）为33.3%，牙周炎指数（PM指数）下降47%。因此，对于饮用含氟水的城镇，也建议广泛采取口腔卫生措施作为二级预防手段。
