Concentración de fluoruros en sal de cocina y agua que ingieren los habitantes de Villavicencio-Colombia

Resumen

Objective. To analyze concentrations of fluorides in cooking salt and water consumed by habitants of Villavicencio-Meta-Colombia. Methods. Descriptive study on 180 water samples from the aqueducts that distribute water in Villavicencio and 47 houses from the distant points of the distribution network of each aqueduct, taken during rainy and summer seasons. Samples from five different lots, from 17 companies distributing bottled water and samples from five different lots of eight brands of salt of kitchen distributed in the city were tested. The fluoride measurements were performed in the Public Health laboratory of the department of Meta, by physicochemical analysis with selective ion electrode, Were performed Measures of central tendency and comparison of data heterogeneity using the Mann-Whitney U test and the Kruskal Wallys test, with values of significance <0,05. Results. The average concentration of fluoride in water from the aqueducts was 0,067 ppm (IC 95%; 0,06-0,07) for surface water aqueducts (rivers); Of 0,101ppm (IC95%; 0,09-0,11) for deep well aqueducts and in bottled water was 0,088 ppm (IC95%; 0,07 – 0,09) with significant differences (p = 0.02). The average concentration fluoride in salt was 186,71 ppm (IC95% ; 179,63-193,18); With significant differences between the averages of fluoride concentration in each brand. (p = 0.01). Conclusions. Fluoride concentrations in drinking and salt water are within the limits established by national and international standards and therefore would not in themselves be important factors for dental fluorosis in this population.
