Influence of topical applications of fluoride of gels of the surface roughness of glass ionomer cements

Abstract

Objective: To evaluate the surface morphology of four glass ionomer cements when submitted to 1.23% acidulated phosphate fluoride topical application and 2% sodium fluoride. Material and Method: Ten specimens of each material (Ketac Molar Easymix, Maxxion R, Vitro Molar and Vitremer) were made. Surface roughness testing was made before and after topical application of fluoride with neutral fluoride gel to 2% and topical application of fluoride gel acidulated phosphate to 1.23% Data were analyzed statistically by Tukey’s test and T's teste at 5% significance level. Results: The results demonstrated alterations on surface morphology after treatment with acidulated phosphate fluoride gel. Maxxion presented the biggest variation on morphological standard after treatment with acidulated gel, continuing, in decreasing order, by Ketac Molar Easy Mix and Vitromolar, while Vitremer samples did not presented significant alterations. Conclusion: The topical acidulated fluoride presented surface alterations in all evaluated materials
