Effect of effervescent C vitamins on the surface roughness and color stability of composite resins: A SEM study.

Ebru Delikan

Objective To investigate the effect of effervescent vitamins C on the color change and surface roughness of resin composites. Methods 30 specimens (8 mm*2 mm) were prepared for each restorative material (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 (Vita Easyshade V, Vita Zahnfabrik, Bad Säckingen, Germany), and initial surface roughness was measured with roughness tester (Mitutoyo SJ-410 Surftest Analyzer).
