Aim This was to investigate the effects of Klorhex, Tantum Verde, Kloroben, and Listerine on the discolouration of composite resin, compomer, giomer, and resin-modified glass ionomer. Methods 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 (ΔE*) values were obtained and the results were evaluated statistically. Results The ΔE* 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. Conclusions 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.
