    The objective of this study was to determine the fluoride concentration in bottled water sold in Lima, Peru, using a deductive and hypothetical method, with a quantitative approach and an observational, prospective, and cross-sectional design. Methodology: The sample consisted of three batches of bottled water from the following brands: San Mateo, San Luis, and Cielo, where the fluoride concentration was measured with a potentiometric instrument using the Ion Plus Sure-Flow Fluoride Electrode 9609BNWP, Thermo-Orion, coupled with the Multiparametric VERSA STAR VSTAR-40A2, Thermo-Orion for reading. The results showed that the average fluoride concentration in San Luis bottled water was 0.0126 ppm, in San Mateo it was 0.1840 ppm, and in Cielo bottled water, it was 0.1268 ppm. The study concluded that the analyzed bottled waters did not contain adequate levels of fluoride, and significant differences were found between San Luis and Cielo (p=0.016), San Luis and San Mateo (p=0.000), and Cielo and San Mateo (p=0.016). San Mateo had the highest fluoride concentration, while San Luis had the lowest. Furthermore, the bottled water brands studied did not meet the optimal fluoride levels of 0.7 ppm F recommended by the American Association of Drugless Practitioners (AADP).
