“…These solutions were chosen as the most common daily beverages known to have staining potentials and cover a wide variety of staining shades. 32,78,79 Distilled water was chosen as a control group ( Figure 6). Four weeks were chosen in according to previous studies, which is equivalent to 2.5 years of clinical aging.…”

“…20,22,28,29 Extrinsic staining can be managed by maintaining polished composite surface initially and later through periodic repolishing. [30][31][32][33][34] Resin-based composite materials represent the most commonly used restorative material in aesthetic restorations. These materials are composed of a polymeric matrix based on dimethacrylate monomers and inorganic fillers and are coated with methyl methacrylate-functional silanes to bond the particles to the matrix, as well as a photo-initiator system that permits photoactivation using a light source.…”

“…These materials are composed of a polymeric matrix based on dimethacrylate monomers and inorganic fillers and are coated with methyl methacrylate-functional silanes to bond the particles to the matrix, as well as a photo-initiator system that permits photoactivation using a light source. 32,[35][36][37][38][39][40][41][42] Most resin-based composites utilize camphorquinone (CQ) as the initiator system. CQ is a stable yellow compound with an unbleachable chromophore group.…”

“…The presence of CQ in the resin leads to an undesirably yellowish effect in the final cured resin-based material; to complicate the problem further, this yellowing effect increases with aging. 32,[43][44][45][46][47][48] Later on, a different photo-initiator (monoacylphosphine oxide (Lucirin TPO)) system has been introduced that is designed to improve polymerization kinetics and reduce photo-yellowing effects. 45,[49][50][51][52][53] The use of Lucirin eliminated the amine group, thereby increasing color stability upon aging.…”

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.

This study compares the color stability of dental reinforced computer-aided design/computer-aided manufacturing (CAD/CAM) hybrid composite blocks to that of regular blocks. One hundred fifty disc-type specimens (n = 15) were prepared from five sets of hybrid composite blocks (Cerasmart-200/Cerasmart-300, KZR-CAD HR/KZR-CAD HR3, Estelite Block/ Estelite-P Block, Avencia Block/Avencia-P Block, Mazic Duro/Duro Ace). The specimen color and translucency parameter (TP) were assessed using a spectrophotometer before and after immersion in staining solutions (water, 10% ethanol, simulated red wine). Changes in color (ΔE) and translucency (ΔTP) of specimens were calculated. The data were analyzed using the analysis of variance (ANOVA) and Tukey’s post hoc test (p < 0.05). Microstructural features of the hybrid composite blocks were also examined using FE-SEM. Immersion in deionized water or 10% ethanol made no significant color or translucency changes (except for Avencia-P Block); however, the simulated red wine caused significant changes to the color and translucency of almost all specimens, especially after 4 weeks of immersion. The reinforced hybrid blocks (except for Estelite-P Block and Duro Ace) showed lower color stability than corresponding regular blocks. Avencia-P Block showed significantly reduced color stability compared to Avencia Block. Even in deionized water and 10% ethanol, Avencia-P Block showed perceptible ΔE and decreased translucency. Estelite Block/ Estelite-P Block and Mazic Duro/Duro Ace showed better color stability than the other materials tested.
