Purpose: To evaluate the effect of SARS CoV-2 effective mouthwashes on the color change (Delta E), translucency parameter (TP) and average surface roughness (Ra) of a nanofill resin composite (Filtek Ultimate). Methods: 91 composite specimens (10 mm in diameter, 1 mm thickness) were prepared using a stainless-steel mold and randomly divided to seven groups as follows: Group 1 (CHX): 0.12% CHX digluconate + 0.15% benzydamine hydrochloride (96% alcohol), Group 2 (HAc): hypochlorous acid (500 ppm), Group 3 (PVP-I): 1% povidone iodine, Group 4 (H2O2): 1.5% hydrogen peroxide, Group 5 (CHX + C): 0.09% chlorhexidine digluconate + cyclodextrin + citrox, Group 6 (CPC): 0.075% cetylpyridinium hydrochloride, Group 7 (Control): artificial saliva. The initial color values were determined by a spectrophotometer on both white and black backgrounds. The specimens were immersed in 20 mL mouthwash for 1 minute with a 12-hour interval. The Ra, AE and TP were determined after 1, 2 and 3 weeks. Data were analyzed using repeated measures ANOVA, one-way ANOVA, post-hoc Bonferroni and Tukey tests (P< 0.05). Results: The highest and the lowest AE3 (after 3 weeks) value were observed in H2O2 (1.57 +/- 0.29) and CHX (0.92 +/- 0.17) groups, respectively. The CHX and CPC groups demonstrated significantly lower AE3 values than the control group (P< 0.05). CHX, HAc and PVP-I significantly affected the TP (P< 0.05). None of the groups demonstrated any significant changes of Ra scores (P> 0.05).
