| Abstract | ||
| Objective: To assess the impact of different aging periods on surface color stability and marginal discoloration of Surefil one self-adhesive composite and Filtek One bulk-fill composite. Materials and methods: A total of 28 class I cavities were prepared in the molar teeth of 14 different patients using split mouth technique and then were divided randomly into two groups (Group 1: Surefil one self-adhesive composite – Group 2: Filtek One bulk-fill composite). A VITA Easyshade spectrophotometer was utilized to measure the baseline surface color of the restoration after 24 hours and degree of surface color change after 3 and 6 months of composite restoration placement and then degree of color change was measured using the CIE L*a*b* system. All discolored restored molar teeth were polished using Sof-Lex aluminum oxide discs and then the degree of surface and marginal color improvement was determined and was then compared to the baseline color measurements. Data was analyzed using Kolmogorov-Smirnov, Shapiro–Wilk and Pearson’s Chi square tests. Results: Filtek One bulk-fill composite resulted in statistically less significant surface color change and marginal discoloration than Surefil one self-adhesive composite after aging. Filtek One bulk-fill composite resulted in higher degree of surface and marginal color improvement of the restoration after polishing than Surefil one self-adhesive composite. Conclusions: Aging had a detrimental effect on the degree of surface and marginal color stability of resin composite restorations regardless of the resin composite material composition. For discolored resin composite restorations, polishing was an effective way to remove superficial stains. | ||
