Comparison of Fluoride Ion Release from Fluoride Gel in Various Solvents

Abstract

Objective: The aim of this study was to determine the concentration of fluoride ions present in var-ious solvent solutions and compare it to the label amount of fluoride concentration. Material and methods: The gel containing amine fluoride and sodium fluoride was compared to gel containing sodium fluoride only. The solvents used in this study were distilled water, redistilled water, tap water, 0.9% sodium chloride solution and the artificial saliva. The amount of fluoride ion (F -) was determined by the use of fluoride ion-selective electrode. The ANOVA and the Post hoc Tukey’s test were used. The significance level was α = 5%. Results: The differences between F –ion release in various solvents were statistically significant (p < 0.05). The F –ion concentrations measured in both gels’ redistilled water solutions were higher than the label concentration. There was a significant difference in fluo-ride ion release in sodium fluoride only gel solutions. Fluoride ion release was significantly different in combined fluoride gel solutions. Conclusions: Amine fluorides do not interact with other ions pres-ent in the solution, whereas F –ion release from sodium fluoride alters when other ions are dissolved in the same solution. Amine fluorides deliver F -ions for caries prevention more efficiently
