The aim of the study was to determine the concentration of fluoride in natural mineral waters marketed in Spain in order to prevent tooth decay without the risk of causing dental fluorosis
Descriptive and cross-sectional study during 2012.
Natural mineral waters marketed in Spain.
Three bottles with different bottling dates of 109 natural mineral waters (97 Spanish and 12 imported brands).
Determination of fluoride by ion chromatography
Median fluoride concentrations of the natural mineral waters bottled in Spain was 0.22 (range 0.00-4.16; interquartile range:0.37). Most samples (61 brands, 62%) contained less than 0.3mg/L. There are 19 Spanish brands with more than 0.6 mg/L. The median level in imported brands was 0.35 (range 0.10-1.21; interquartile range: 0.23). Only 28 of the 109 brands examined (25.6%) specified the fluoride content on the label. Good correlation was observed between the concentrations indicated and those determined.
Fluoride concentrations in natural mineral waters showed high variation. Given the growing consumption of natural mineral waters in Spain, this type of information is important to make proper use of fluoride in the primary prevention of dental caries.
本研究旨在测定西班牙市场上销售的天然矿泉水中氟化物的浓度，以预防龋齿且无导致氟斑牙的风险。
2012年进行的描述性横断面研究。
西班牙市场上销售的天然矿泉水。
109种天然矿泉水（97个西班牙品牌和12个进口品牌）的三瓶不同装瓶日期的产品。
采用离子色谱法测定氟化物。
西班牙装瓶的天然矿泉水氟化物浓度中位数为0.22（范围0.00 - 4.16；四分位间距：0.37）。大多数样品（61个品牌，62%）氟化物含量低于0.3mg/L。有19个西班牙品牌氟化物含量超过0.6mg/L。进口品牌的中位数水平为0.35（范围0.10 - 1.21；四分位间距：0.23）。在检测的109个品牌中，只有28个（25.6%）在标签上标明了氟化物含量。所标明的浓度与测定的浓度之间存在良好的相关性。
天然矿泉水中氟化物浓度差异很大。鉴于西班牙天然矿泉水消费量不断增加，这类信息对于在预防龋齿的一级预防中合理使用氟化物很重要。
