In vitro cumulative effect of topical application of fluoride gels on the surface of aesthetic restoration materials.
It has been shown that the application of topical acidulated fluoride products on composite resins and porcelains promotes changes on their surfaces. However, the reduced time of clinic treatment does not always cause significant effects. Therefore, the therapy is normally repeated, suggesting the hypothesis for a cumulative effect. The aim of this study was to examine if the repetition of application can potentiate the effect. Samples of different composite resins received topical application of four fluoridated commercial gel products with neutral and acid pH under different experimental conditions. The samples were subsequently stained to show the degree of surface alteration. A variable superficial alteration was observed in those samples that received the acidulated fluoride compounds.
