Abstract
The aim of this study was to measure the concentration of fluorides in tap water in northern Croatian town Čazma and commercially available bottled drinks. Materials and Methods: Fluoride content was assessed by fluoride-selective electrode in tap water and commercial drinks from public supply. The pH was assessed by hydrogen ion-selective electrode. Results: Fluoride content in tap water was 0.313 mg F-/L. In commercially available bottled drinks fluoride concentration was the highest in carbonated mineral water (0.34 – 1.5 mg F-/L), followed by some ice tea drinks (0.06 – 0.74 mg F-/L). Non-carbonated waters, carbonated soft drinks and noncarbonated soft drinks had very low fluoride concentration and it amounted to <0.01 mg F-/L, 0.02 mg F-/L and 0.06 – 0.15 mg F-/L, respectively. The pH in carbonated drinks was 2.36 – 2.68 and 3.08 – 3.64 in juices. Conclusion: Low concentration of fluorides in soft drinks and low pH in combination with added sugars could be cariogenic. The results obtained in this investigation could be used in planning preventive measures.
