Abstract :Objective: To investigate the effect of effervescent vitamins C on the color change and surface roughness of resin composites. Methods: 30 specimens insert ignore into journalissuearticles values(8 mm*2 mm); were prepared for each restorative material insert ignore into journalissuearticles values(G-ænial Posterior, Solidex);. The specimens were polymerized with LED device for 20 seconds and were incubated in distilled water for 24 hours for post-polymerization. Initial color values were measured using a spectrophotometer insert ignore into journalissuearticles values(Vita Easyshade V, Vita Zahnfabrik, Bad Säckingen, Germany);, and initial surface roughness was measured with roughness tester insert ignore into journalissuearticles values(Mitutoyo SJ-410 Surftest Analyzer);. The specimens were randomly divided into 3 groups according to their immersion solution insert ignore into journalissuearticles values(Redoxon, Ocean efervit, and distilled water);. During the 28-day test period, the specimens were immersed in the solutions 2 times a day. Color changes and surface roughness measurement procedures were repeated. Data were subjected to One-way ANOVA, Tukey test, and t-test insert ignore into journalissuearticles values(p=0.05);. Results: When the color change insert ignore into journalissuearticles values(ΔE00); results are examined statistically; the highest ∆E values were observed in the Redoxon group, regardless of the restorative material. G-ænial Posterior specimens from both study groups and Solidex specimens incubated in Redoxon showed clinically unacceptable discoloration. When the average roughness values insert ignore into journalissuearticles values(Ra); are analyzed statistically, roughness values above the threshold surface roughness insert ignore into journalissuearticles values(Ra=0.2 µm); was detected in all groups. However, no statistically significant difference between groups insert ignore into journalissuearticles values(p>0.05);. Conclusion: Despite the fact that effervescent C vitamins significantly increased the discoloration of the tested composite resins, not cause a statistically significant difference in surface roughness.
