PIZZATTO, Eduardo et al. Analysis of fluoride concentration in solutions prepared at dispensing pharmacies. RSBO (Online) [online]. 2011, vol.8, n.3, pp. 294-298. ISSN 1984-5685.

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.
