Fluoride concentrations in water consumed in the Region of Murcia are not sufficient to prevent dental caries
Abstract
Introduction: Dental caries remains the most frequent chronic disease in childhood and is considered a public health problem. Fluoride has proven effectiveness in the prevention of caries and drinking water is the main source of fluoride intake. The objective of this study was to determine fluoride concentrations in tap water from 10 areas and in 10 bottled waters sold in the Region of Murcia.
Materials and Methods: The concentration of fluoride in water was determined using a fluoride ion-selective electrode with a direct technique previously calibrated with standard fluoride concentrations prepared with TISAB II.
Results: In tap water, fluoride concentrations from 0.09 to 0.18 mgF/L (ppm) were detected; in bottled waters the concentration of fluoride varied from 0.04 to 0.50 ppm.
Conclusion: Fluoride is present in the water consumed in the Region of Murcia but in concentrations that do not prevent dental caries. Fluoride supplements should be prescribed in children at high risk of caries, and for this, all external sources of fluoride intake, including water, must be accounted for.
