Methods: A composite resin, Valux Plus and a compomer , F 2000 were evaluated. The coloring solutions used for the staining tests were: Klorhex, Tantum and Listerin as oral rinses. A colorimetric evaluation according to the CIE L*a*b* system was performed after experimental periods of 3, 7, and 10 days. Results: According to the statistical analysis(ANOVA and Duncan's multiple range test ) Tantum caused the greatest color change for the compomer and Klorhex for the composite resin. The compomer was more affected than the composite resin at the end of 10 days and for 3 staining solutions(p<0.05). Conclusions: Within the limitations of this study the compomer samples showed more discoloration than the composite samples in oral rinse solutions. | ||
