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.
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.
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.
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.
水中氟化物浓度（F conc）是龋齿和氟斑牙发生的主要决定因素。在农村社区的大多数家庭中，尤其是在发展中国家，主要依赖袋装水作为替代低成本饮用水。本研究旨在确定尼日利亚西南部伊巴拉帕地区常见商业包装袋装水中的氟化物浓度。
采用便利抽样法对尼日利亚西南部伊巴拉帕地区所有用于饮用的商业包装袋装水进行观察性研究。从阿耶特（2份）、伊博拉（6份）和兰拉特（5份）采集了13份袋装水样本。通过直接分析，使用氟离子选择性电极对袋装水中的F conc进行了三次测定。还测量了水的温度和pH值。使用SPSS 23版对结果进行分析。
F conc、温度和pH值范围分别为0.03mgF/l - 2mgF/l、26.4°C - 27.2°C和6.90 - 8.19。所有样本中最低F conc在pH值为6.90时为0.03ppm，最高在pH值为7.78时为2ppm。2份（15.4%）、8份（61.5%）和3份（23.1%）水样的F conc分别为0.5 - 0.6mgF/l、<0.5mgF/l和>0.6mgF/l。没有袋装水在其标签上标注氟化物含量。
袋装水的F conc各不相同，大多数样本浓度较低。需要关注饮用水中氟化物的低水平和高水平，以确保安全和预防效益。
