“…Since the previous reports indicated that measuring quantitative color alterations by using CIE L ∗ a ∗ b with proper spectrophotometry and colorimetry techniques have several advantages such as repeatability, sensitivity, and objectivity, the spectrophotometry was used for calculating Δ E ∗ values for each material/pediatric drug in this study [25, 26, 29, 31]. …”

“…L ∗ color coordinate represents lightness or brightness, a ∗ represents greenness (positive) and redness (negative), and b ∗ represents yellowness (positive) and blueness (negative). Numeric description of color permits precise definition of the magnitude of the color difference between objects [28, 29]. The color difference indicates whether a change in overall shade can be perceived by a human observer.…”

“…Clinical color matching may be rated according to these Δ E ∗ values and O'Brien [30] had reported that, based on clinical studies, the Δ E ∗ values below 3.5 unit are unacceptable. Several studies [28, 29, 31] also considered the color differences greater than 3.5 between veneers and the teeth as clinically unacceptable.…”

Background. The chronic recommendation of pediatric drugs could exhibit erosive and cariogenic problems. Objective. To evaluate the effects of different pediatric drugs on the color stability of various restorative materials. Methods. Five specimens (1 mm × 3 mm) were prepared and immersed in ten different pediatric drugs and agitated every 8 hours daily for 2 min up to 1 week. Between immersion periods, the samples were stored in artificial saliva. After 1-week period, ΔE⁎ values were calculated. Two-way ANOVA and Fisher's LSD test were used for statistical analysis at a level of p < 0.05. Results. ΔE⁎ values were only significantly influenced by restorative material factor (p < 0.001) and varied in the range of 2.08 and 6.55 units for all drugs/restorative materials. The highest ΔE⁎ was found in Ferrosanol B-composite (6.55 ± 1.38) and the lowest one was found in Dolven-glass ionomer (2.08 ± 0.40) pairwise. The most prominent ΔE⁎ value elevations were obtained in composite material compared to the compomer and/or glass ionomers in Macrol, Ferrosanol B, and Ventolin (p < 0.001; for all) and also for other drugs (p < 0.05). Dolven exhibited significantly higher values compared to Augmentin (p = 0.021), Macrol (p = 0.018), and Ventolin (p = 0.013) in compomer group. Conclusion. The clinically perceptible color changes for tested composite/pediatric drug pairwise can be more problematic than compomer and glass ionomers in pediatric dentistry.

“…Dentistry faces the challenge of quantifying, predicting, and controlling the color changes inherent to treatment with laminate veneers. Most investigators studying this topic (Öztürk et al ; Turgut and Bagis ; Turgut et al ) have computed color changes by means of electronic devices using the CIELAB system, owing to its international standardization and its objectivity. Nevertheless, the color coordinates (CIELAB system) form part of a language with which most dentists are not familiar.…”

The final color of a ceramic restoration is influenced by both the ceramic thickness and the cement shade. This study aims to evaluate the color stability according to the 3D Master System of e.max ceramic discs after bonding with different shades of luting agents. A total of 120 e.max.Press 2M1 HT ceramic discs (60 discs of 1‐mm thick and 60 discs of 0.5 mm thick) and three different values of Variolink Veneer cement were used (−3, 0, +3) for the cementation process. An Easyshade compact device was used to measure color shade tabs, according to the 3D Master System, on the discs both before and after the cementation protocols. Bivariate and multivariate analyses were carried out with the spss v.21. After bonding with the different luting agents, only 30% remained as 2M1: specifically, 22% of the thinner discs and 37.3% of the thicker discs. In general, the effect of bonding increased the value and the chroma of the shade to a significant extent. Regression analyses revealed that the most significant predictor for all color parameters was cement shade, the thinner disc group bonded with −3 cement being the most unstable subgroup. According to the 3D Master System, the shade of the luting agent was the main predictor of the final color. However, the final color seems to be somewhat unpredictable, at least according to the modulating factors evaluated in the present study.

The color stability of resin cements is essential for aesthetic restorations. Aim: To evaluate the influence of shade and aging time on the color stability of two light-cured and two dual-cured resin cements. Methods: The CIE-Lab color parameters (n=6) were measured immediately after sample preparation and at 7, 30 and 90 days of aging in distilled water. The color difference (∆E) was calculated and then analyzed by three-way ANOVA for repeated measures and Tukey's HSD test (α=0.05). Results: ∆E was higher for transparent resin colors, followed by dark and light colors. The mean values of ∆E were lower for both light-cured resin cements compared to the dual-cured cements. As the aging time increased, ∆E values increased. Conclusions: The light-cured resin cements showed greater color stability. The lighter shades of luting were more likely to display a greater color change.

Effect of Ultraviolet Aging on Translucency of Resin‐Cemented Ceramic Veneers: An In Vitro Study

Abstract: The TP of the same color of resin cements varied related to the type or brand. Aging caused both the ceramics and cemented ceramics to become more opaque.
