“…In our study all composite disks after storage time in staining solutions, showed detectable staining (∆E ≥ 3.3) and the highest staining was observed for the coffee solution. This finding is in line with other studies (18,19). In short immersion time, coffee cause less discoloration than tea because of higher polarity and delayed release of pigments (13).…”

Background: One of the concerns in using composite resins is color change. The aim of this study was to investigate the effect of preheating on color stability of composite resins when immersed in coffee and tea. Material and Methods: this experimental study included 60 composite disks. The samples were divided into 2 groups, one group prepared at room temperature and the other prepared at 68°C. After curing, the samples were placed in 37 °C distilled water for 24 hours. The color of the samples was measured (t0) using spectrophotometer according to CIE-L*a*b* system. The samples of each group were then divided into 3 subgroups and respectively immersed in distillated water, coffee and tea for 30 days and the final color (t1) was measured. The difference between the measured colors was calculated (∆E) and the results were analyzed using version 21.0 of SPSS software, Paired t-test, ANOVA, Tukey's test, and Dunnett t-test. Results: The preheated composites showed significantly lower staining in the coffee solution than the room temperature composites (p<0.0001). In contrast, no statistically significant difference was observed for the tea solution (p=0.317). The staining of the preheated composites in distillated water was higher than those in the room temperature, however, the difference was not significant (p=0.99). Conclusions: Within the limits of this study, preheating was effective to improve color stability of composite resin after long time immersion in coffee solution.

“…Some studies have reported that composite resins with less inorganic fillers experience greater color change because a higher volume of resin matrix results in greater water sorption [3,7, 13]. On the other hand, TEGDMA contained in Z350XT results in the release of high amounts of monomer and greater color change in the composite [12].…”

Objectives:Color stability of composite resins has a significant role in their durability and clinical service. Considering the increasing use of composite resins and their gradual discoloration, this study aimed to assess the efficacy of Listerine whitening mouthwash for color recovery of two discolored composite resins.Materials and Methods:This in-vitro experimental study was performed on 20 samples fabricated of Filtek Z350XT (3M ESPE, St. Paul, MN, USA) and IPS Empress Direct (Ivoclar Vivadent, Schaan, Liechtenstein) composite resins. Primary colorimetry was performed using a spectrophotometer. The samples were immersed in a coffee drink for 7 days. They were then immersed in Listerine mouthwash for 4 minutes daily for 56 days. After this period, the color change of composite resins was reevaluated. Data were analyzed using repeated-measures analysis of variance (ANOVA) and t-test.Results:The primary color change of Z350XT after immersion in coffee was 1.6 times greater than that of IPS composite (P<0.0001). The color recovery of IPS and Z350XT after immersion in the mouthwash was 1.06±0.58 (P<0.01) and 2.58±1.65 (P<0.001) units, respectively. The color change of Z350XT after exposure to the mouthwash was 25% (1.4 times) greater than that of IPS (P<0.01).Conclusion:Both composite resins experienced a clinically unacceptable discoloration after exposure to coffee (ΔE>3.3). Filtek Z350XT showed greater color change than IPS. Use of Listerine whitening mouthwash caused significant color recovery in both composite resins.
