SZESZ, Anna Luiza et al. Influence of different drinks on the resin composites' color stability. Odontol. Clín.-Cient. (Online) [online]. 2011, vol.10, n.4, pp. 323-328. ISSN 1677-3888.

The main concern of patients in dentistry is the aesthetics of the smile. In this sense, the manufacturers of dental materials have improved, like the resins that are used for restorations in anterior and posterior teeth and that have excellent aesthetics and good mechanical properties. The aim of this study is to evaluate the influence of different drinks (wine, Coke and coffee) on color stability of composite resin with and without brushing with toothpaste. Specimens were fabricated with composite resin, which underwent an initial assessment of color and divided into groups that were immersed for 30 and 60 days in their net regarding the experimental groups. After this period of immersion, the color was measured again, and the specimens were submitted to brushing, to assess whether toothbrushing is an effective method to prevent or reduce the staining in composite resin, caused by drinking in study. Drinks in the study affected the color stability of composite resins, with color changes visible. Brushing was not effective in removing the pigment in red wine, however, resulted in improved staining caused by Coke.
