Influence of topical applications of fluoride of gels of the surface roughness of glass ionomer cements. Rev. Bras. Odontol. [online]. 2015, vol.72, n.1-2, pp. 41-46. ISSN 1984-3747.

To evaluate the surface morphology of four glass ionomer cements when submitted to 1.23% acidulated phosphate fluoride topical application and 2% sodium fluoride. 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. Data were analyzed statistically by Tukey’s test and T´s test. Maxxion presented the biggest variation on morphological standard after treatment with acidulated gel, continuing, in decreasing order, by Ketac Molar Easy Mix and Vitromolar. The topical acidulated fluoride presented surface alterations in all evaluated materials.
