Background and Objective: One of the most important factors in the success of anterior composite restorations is color stability in different situations in mouth. The aim of this study was to evaluate the color stability of four anterior composites in the staining solutions (tea and coffee) and under Ultra-Violette (UV) accelerated aging using spectrophotometer.
Methods: This in-vitro study was conducted on 80 samples of four composites (Grandio, G-aenial, Kalore and Estelite Σ quick). Samples were divided into four subgroups (5 samples in each subgroup): immersion in coffee (for 48 hours), tea (for 48 hours), distilled water (as the control group) and exposure to UV for 168 hours. The color of the samples was evaluated by the spectrophotometer before and after the various conditions using the CIE Lab system and color changes (ΔE*ab) were calculated.
Findings: In all composites, the maximum and minimum levels of color changes were related to the groups immersed in coffee and distilled water, respectively. The significant color change was observed in all subgroups (ΔE*ab>3.3), except for the control groups and tea-Estelite Σ quick (ΔE*ab=2.79). The highest color change was related to immersion in coffee-Grandio (ΔE*ab=9.084) and the lowest observed in immersion in distilled water-Estelite Σ quick (ΔE*ab=0.836). In coffee immersion subgroups of Grandio and Kalore, higher color change was seen compared to Estelite Σ quick (p=0.02 and p=0.028, respectively).
Conclusion: Long-term exposure to tea and coffee and UV accelerated aging leads to clinical color change in Grandio, G-aenial, Kalore and Estelite Σ quick composites.
Keywords: Spectrophotometry, Composite Resins, Coffee, Color.
