BACKGROUND: Fluoride concentration (F conc) in water is a major determinant for the occurrence of dental caries and dental fluorosis. In most homes of rural communities, especially in developing countries, there is a major reliance on sachet water as an alternate low-cost drinking water. This study aims to determine the fluoride concentrations of common commercially packaged sachet water in Ibarapa land, Southwestern, Nigeria.
METHODS: An observational study was conducted using convenience sampling of all commercially packaged sachet water for drinking in Ibarapa land, Southwestern, Nigeria. Thirteen samples of sachet water were obtained from Ayete (2), Igboora (6) and Lanlate (5). F conc of the sachet water was determined in triplicate using the Fluoride Ion-Selective Electrode by direct analysis. Temperature and pH of water were also measured. Results were analysed using SPSS version 23.
RESULTS: The F conc, temperature and pH range were 0.03 mgF/l - 2 mgF/l, 26.4°C - 27.2°C and 6.90 - 8.19 respectively. The minimum F conc in all samples was 0.03ppm at pH 6.90 while maximum was 2ppm at pH 7.78. F conc in 2 (15.4%), 8 (61.5%) and 3 (23.1%) water samples were 0.5-0.6 mgF/l, <0.5 mgF/ l and >0.6 mgF/l respectively. No sachet water had fluoride levels printed on their labels.
CONCLUSION: F conc of the sachet water varied, with the majority of samples having low concentrations. Attention needs to be paid to both low levels and high levels of fluoride in drinking water to ensure safety and protective benefit.
