Abstract
DALL’ONDER, Ana Paula; FABRUCCINI FAGER, Anunzziatta; ALVAREZ LOUREIRO, Licet and NAOMI HASHIZUME, Lina. Fluoride concentration in household salt marketed in Montevideo, Uruguay. Odontoestomatología [online]. 2021, vol.23, n.38, e213. Epub Dec 01, 2021. ISSN 0797-0374. https://doi.org/10.22592/ode2021n37e213.
Objectives:
To evaluate the fluoride (F) concentration in salt marketed in Montevideo, Uruguay.
Method:
Fourteen household salt brands marketed in Montevideo were analyzed to determine their free fluoride concentrations. Salt samples were weighed, diluted with deionized water, mixed with TISAB II, and F concentrations were determined using a fluoride-specific electrode connected to an ion analyzer.
Results:
Most salt brands showed values lower than 250 mgF/kg. Coarse salt samples showed higher F concentrations compared to the refined salt samples (p < 0.05). Salt brands with sodium fluoride had higher F concentrations than those with potassium fluoride (p < 0.05). Only two brands had F concentrations close to the content included in the product packages.
Conclusions
Household salt brands marketed in Montevideo (Uruguay) have significant variability in their F concentrations.
