Correlation of fluoride intake to total bone mass at Asembagus, Situbondo, Indonesia

Fluoride is a non-organic substance with the most reactive element and the highest electronegativity. Most humans are exposed to fluoride through food and water intake. Groundwater is the main source of fluoride toxicity in humans. Excess fluoride intake can cause serious health hazards in humans, such as dental and skeletal fluorosis. The etiological factor of fluoride toxicity is the high fluoride levels in groundwater that will accumulate. This study aimed to examine the correlation of fluoride intake to total bone mass. This study is an analytical observational study with a cross-sectional approach method. The sample size was 10 wells and 23 people aged 18-25 years. The fluoride intake was measured using the 24-hour food recall technique. Total bone mass was measured using Tanita Innerscan Model BC-541. The results discovered fluoride intake with an average of 2.52 mg and total bone mass with an average of 2.5 kg. Linear regression analysis resulted in fluoride intake having a significant correlation to the total bone mass (p-value <0.05). To sum up, this research concluded that fluoride intake correlated negatively significantly, namely, the higher the fluoride intake, the total bone mass will decrease.
