Analysis of fluoride concentration in solutions prepared at dispensing pharmacies

Resumo

Introduction: Fluoride plays an important role in oral health
promotion and is considered important in dental caries prevention
both in children and adults. Fluoride is widely used at high-risk
conditions of caries, when the use of fluoride-containing mouthwashes
is recommended, considering that fluoride itself reduces the risk of
dental caries. Objective: To evaluate the fluoride concentration in
solutions prepared at different dispensing pharmacies in the city
of Curitiba – PR, Brazil. Material and methods: The analysis of
fluoride concentration was preformed through Ion Chromatography
method (DIONEX). Results: The results obtained through this analysis
showed that all solutions presented fluoride concentration above that
required in the dentist’s prescription, varying between 5.48% and
24.02% more fluoride, at absolute concentration. Conclusion: This
finding highlights the increasing risk of fluoride acute intoxication
in cases of accidental ingestion of the solution.
