Fluoride is essential for the growth and development of teeth and bone. Excess or less fluoride consumption can have harmful effects on our bodies. Fluoride level of 0.5-1.5 mg/l is said to be optimized according to the World Health Organization. The level of fluoride varies among the different geographical regions and water sources. It is essential to find out the fluoride content of various water sources used for drinking purposes. The aim of this study was to find the mean concentration of fluoride in drinking water sources of a municipality.
A descriptive cross-sectional study was conducted in a Municipality. The study was conducted from 1 December 2021 to 30 December 2021 after receiving ethical approval from the Ethical Review Board (Reference number: 1134). Water samples were collected and the fluoride content was estimated using 2-parasulfophenylazo-1,8-dihydroxy-3,6-napthalene-disulfonate colorimetric method. The data collected from the laboratory were calculated and presented in the form of a table. Point estimate and 95% Confidence Interval were calculated.
The mean value of fluoride content in 160 collected water samples was 0.369±0.275 mg/l (0.33-0.41, 95% Confidence Interval). Among the different wards, the fluoride content was 0.708±0.27 mg/l in ward number 12 followed by a fluoride content of 0.57±0.19 mg/l in ward number 5.
In this study, the mean fluoride levels were lower when compared with similar studies conducted in similar settings. The levels were lower than that recommended by the World Health Organization. The various controlled methods of fluoridation have to be quickly initiated. Other means of fluoride consumption, like the use of fluoridated toothpaste, has to be recommended.

氟对于牙齿和骨骼的生长发育至关重要。过量或过少的氟摄入都会对我们的身体造成有害影响。世界卫生组织称，氟的最佳摄入量为 0.5-1.5mg/L。不同地理区域和水源的氟含量有所不同。了解各种饮用水源的氟含量至关重要。本研究旨在确定一个市的饮用水源中氟的平均浓度。
这是一项在一个市进行的描述性横断面研究。该研究于 2021 年 12 月 1 日至 2021 年 12 月 30 日进行，研究获得了伦理审查委员会的批准（参考编号：1134）。采集水样，采用 2-对磺基苯偶氮-1,8-二羟基-3,6-萘二磺酸比色法测定氟含量。从实验室收集的数据进行计算并以表格形式呈现。计算点估计值和 95%置信区间。
在 160 份采集的水样中，氟含量的平均值为 0.369±0.275mg/L（0.33-0.41，95%置信区间）。在不同的行政区中，第 12 行政区的氟含量最高，为 0.708±0.27mg/L，其次是第 5 行政区，氟含量为 0.57±0.19mg/L。
在这项研究中，与在类似环境中进行的类似研究相比，平均氟水平较低。该水平低于世界卫生组织的建议值。必须尽快启动各种受控的氟化方法。必须推荐使用含氟牙膏等其他氟化物摄入方式。
