title: [Fluoride content of bottled natural mineral waters in Spain and prevention of dental caries].
abstract: OBJECTIVE
  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
  
  
  METHODS
  Descriptive and cross-sectional study during 2012.
  
  
  METHODS
  Natural mineral waters marketed in Spain.
  
  
  METHODS
  Three bottles with different bottling dates of 109 natural mineral waters (97 Spanish and 12 imported brands).
  
  
  METHODS
  Determination of fluoride by ion chromatography
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
