Fifty disc-shaped specimens from each restorative material (n = 50) were prepared; initial colour values were measured with a spectrophotometer. Forty specimens from each group were placed in the four different types of mouthwashes (n = 10), while the remaining 10 specimens were immersed in distilled water for 2 min, twice a day for a period of 3 weeks. Colour change (Delta E*) values were obtained and the results were evaluated statistically. The Delta E* of composite resin in Klorhex (0.84 +/- 0.37) was significantly lower than that of the other mouthwash groups. Moreover, composite resin showed the least colour change when compared with the other materials in all four mouthwashes. Resin-modified glass ionomer values were significantly higher in Tantum Verde (6.36 +/- 2.82) when compared with the other mouthwashes (p < 0.05). Clinically appreciable discolourations were observed in the resin-modified glass ionomer specimens placed in Tantum Verde and Listerine. Nano-filling composite resins are the most successful aesthetic restorative materials, whereas the commonly used resin-modified glass ionomers exhibit more aesthetically divergent results following the use of mouthwashes.eninfo:eu-repo/semantics/closedAccessComposite resinsGlass ionomer cementsMouthwashesSpectrophotometryArticle19314715310.1007/s40368-018-0341-02-s2.0-8504783526529770926Q1WOS:000433923100004N/A
