“…Polishing was shown to partially reduce discoloration, hence suggesting two mechanisms of extrinsic discoloration, pigment absorption within the polymer matrix and pigment adsorption on material surface . Intrinsic discoloration due to hydrolytic changes in the polymer network seem to have a lesser effect on the overall discoloration as color differences after water storage were reported to be smaller compared to colored storage media . Changes in a * and b * showed less consistency in the tested cohort of composites, without a clear shift toward a specific color on the red‐green or blue‐yellow coordinates.…”

Objective To determine color changes in bulk‐fill composite and universal composite restorations with dissimilar dentin replacement materials in extracted teeth after staining in red wine. Materials and Methods Cylindrical, 4 mm deep, class I cavities were prepared in 140 human molars. Bottom 2 mm was restored with Biodentine (Septodont), everX posterior (GC) or experimental HAP inserts. Each dentin replacement material was covered with a 2‐mm layer of a universal composite Filtek Z250 or Z550 (3M ESPE) or Gradia Posterior (GC). Groups combining top composite layer and the underlying dentin replacement were designated as “composite_dentin replacement.” Filtek Bulk Fill (3M ESPE) and Tetric EvoCeram Bulk Fill (Ivoclar Vivadent) were placed as a single 4‐mm layer. Color measurements were performed using Vita Easyshade 4.0 (Vita Zahnfabrik) initially and after 48‐hours storage in red wine at 37°C. Results Color differences (ΔEoo) ranged between 2.1 ± 0.7 (Z250_HAP) and 7.8 ± 1.1 (Z550_everX). EverX resulted in higher ΔEoo of the overlying composite than HAP (P < .001) and Biodentine (P = .006). Generally, ΔEoo was affected more by decreasing lightness (ΔL′) than changes in chroma (ΔC′). Conclusions EverX resulted in higher ΔEoo of the restoration than Biodentine and experimental HAP after staining in red wine. No significant differences in ΔEoo may be expected in different composites with the same underlying dentin replacement material. The same was generally true for bulk‐fill and universal composites. Clinical Significance Similar extent of color changes may be expected in bulk‐fill and universal composites. Highly translucent everX might exhibit greater color differences irrespective of the capping composite than non‐translucent materials. Clinicians have a wider choice of composite materials to cover a particular dentin replacement material, for example, everX or Biodentine, as similar color differences may be expected in various overlying composite brands.

“…Color changes in Gradia_HAP and Z250 groups were mainly due to changes in chroma (Δ C′ ). Lightness decreased and chroma increased, as with other brands of micro‐ or nano‐sized composites . An exception was shown to be Z550 with lower chroma after staining compared to other composites.…”

Introduction: Exceptional optical properties characterize teeth. As such, an esthetic restorative material should enable the dental professional to imitate the optical properties of natural teeth accurately. IPS Empress Direct was introduced to the market with the claim that it can mimic optically dental tissues with superior clinical performance. Aim: To evaluate the ability of IPS Empress Direct to mimic tooth appearance and color and resist staining. Materials and methods: Three disc specimens were prepared for each shade of enamel and dentin of Lucirin-based composite, IPS Empress Direct (Ivoclar Vivadent) (A1, A2, A3, B1, and B2) (total of 60). The specimens were submitted to colorimetric evaluation in comparison after immersion in 10 different solutions (coffee, coffee with sugar, coffee with milk, red tea, red tea with sugar, red tea with milk, tomato juice, pomegranate juice, coke, and distilled water as a control group) for 4 weeks using spectrophotometric analysis. Results: After plotting the data and conducting linear regression analyses, IPS Empress showed high potential in mimicking the optical properties of natural tooth color according to the CIE color space. Three solutions showed a change in color higher than 3, coffee, coffee with sugar, and red tea. All other solution showed changes in color that are acceptable clinically. Conclusion: IPS Empress Direct can satisfactory mimic teeth appearance and color while manifesting high stability of color resisting staining upon clinical aging.

“…From a clinical standpoint, restoration replacements account for nearly 70% of all restorative dentistry procedures , with discoloration and surface degradation of composite being common indications for replacement. Water plays an important role in the color change and degradation of composites. Restorative dental polymer networks are susceptible to the effects of water: hydrolytic effects vary depending on monomer chemistry and structure of the composite but have the overall outcome of filler–matrix debonding and consequent increased roughness and stain susceptibility .…”

The aim of this study was to investigate the ability of a novel silica (SiO2)‐based nanocoating approach to extend the superficial integrity of current composites. Cylindrical discs (7 × 2 mm) were produced from nanohybrid and nanofilled composites. Specimens in control groups were not coated, but SiO2 nanocoating was performed on specimens in experimental groups (n = 8). Specimens were stored for 24 h in distilled water at 37°C (baseline) and then artificially aged for 15, 90, or 180 d in a low‐pH staining solution. Surface roughness (Ra) was measured using a profilometer, and a goniometer was used to determine surface free energy (SFE). Color change was evaluated by a reflectance spectrophotometer, applying the color distance metric, ΔE00, according to the Commission Internationale de l'Eclairage (CIE) L*a*b* coordinates. Data were subjected to repeated‐measures anova and the Tukey post‐hoc test. Composites presented visually perceptible color changes (ΔE00 > 0.81) as early as 15 d of aging, with significantly higher ΔE00 values recorded over time. Nanocoating with SiO2 significantly reduced the SFE of composites at all storage times, and significantly lower Ra values were identified after aging. Nanohybrid and nanofilled composites were susceptible to substantial hydrolytic superficial degradation and staining, which was dramatically attenuated by the proposed SiO2 nanocoating approach. Nanocoating effectively lowered the SFE of composites, thus minimizing water–composite interactions, which contributed to reduced superficial deterioration and lower stain susceptibility over time.

Influence of composite type and light irradiance on color stability after immersion in different beverages

Abstract: Initial color of resin-based composites can change after immersion in staining beverages. However, the best color stability was obtained by the nanocomposite photo-activated by a light-curing unit of higher irradiance.
