Abstract :Purpose: Recently, many whitening mouthrinses have appeared on the market with different ingredients due to their ease of use and low costs. Whether these mouthrinses change the color of composite resins has been a matter of curiosity. The aim of this study was to investigate the effect of whitening mouthrinses with different chemical structures on the color stability of a Bis-GMA free resin composite. Materials&methods: Seventy disc-shaped specimens insert ignore into journalissuearticles values(8 mm x 2 mm); were prepared from a Bis-GMA free composite resin and randomly divided into seven groups, according to the mouthrinses insert ignore into journalissuearticles values(n=10);: Listerine Advanced White, Colgate Optic White, Perfect White Black, Crest 3D White, Pasta Del Capitano, Oral B 3D White Luxe. The control group used in the study was distilled water. After the baseline color measurement values were recorded with a spectrophotometer insert ignore into journalissuearticles values(Vita Easy Shade V, Vita Zahnfabrik, Bad Sackingen, Germany);. At the end of the keeping period, color measurements were repeated and changes in color values were calculated insert ignore into journalissuearticles values(ΔEab); using the CIE L*a*b* color system. Statistical analysis of the values obtained was made according to Kruskal Wallis test insert ignore into journalissuearticles values(p <0.05);. Results: All samples demonstrated color changes within clinically acceptable limits in whitening mouthrinses after immersion insert ignore into journalissuearticles values(ΔEab = 1.005 - 2.062);. There was no statistically significant difference among the whitening mouthrinses insert ignore into journalissuearticles values(p <0.05);. Conclusion: It may be concluded that the whitening mouthrinses used in this study did not cause a significant color change during our holding time in Bis-GMA free composite resin.
