Color stability of esthetic restorative materials: a spectrophotometric analysis
2016
Objective: The aim of this in vitro study was to evaluate the color stability of different restorative materials (one microfilled composite, one nanofilled composite, one nanohybrid composite and one Ormocer-based composite) after exposure to different staining solutions (coffee, cocacola and red wine). Material and methods: All materials were polymerized into silicon rings (2mm 6mm 8mm) to obtain specimens identical in size. Thirty cylindrical specimens of each material were prepared. They were immersed in staining solutions over a 28-day test period. A colorimetric evaluation according to the CIE Lab system was performed by a blind trained operator at 7, 14, 21, 28 days of the staining process. The Shapiro–Wilk test and Kruskal–Wallis ANOVA were applied to assess significant differences among restorative materials. The paired t-test was applied to test which CIE Lab parameters significantly changed after immersion in staining solutions. Results: All restorative materials showed clinically perceptible color differences after immersion in coffee. L and b values showed the highest variability. Coca cola and red wine did not influence the color stability for all restorative materials except for Filtek Supreme XTE. Conclusions: Coffee caused a significant color change in all types of tested composite resins. Filtek Supreme XTE demonstrated alone a staining susceptibility to red wine; no other significant differences among the materials were demonstrated. Long-term exposure to some food dyes (coffee in particular) can significantly affect the color stability of modern esthetic restorative materials regardless of materials’ different composition.

Aim: The aim of this in vitro study is to assess the color stability of different esthetic veneer restorative materials (feldspathic ceramic, hybrid ceramic, zirconia-reinforced lithium silicate glass ceramic, and composite resin) after being exposed to commonly consumed beverages that have staining potential. Materials and methods: Sixty specimens were prepared into rectangular blocks with fixed dimensions of 10 × 12 × 2.5 mm. Machinable feldspathic ceramic (FC), zirconia-reinforced lithium silicate glass ceramic (LS), and a hybrid ceramic (HC) were milled using CAD/CAM (n = 15), and specimens of microparticle composite resin (MPC) were manually prepared by with the same dimensions (n = 15). All specimens were randomly divided into three subgroups (= 5) according to immersing solutions used (coffee, black tea, and red wine). All specimens were immersed for a period of 72 hours. A colorimetric evaluation was done for each specimen before and after immersion using a spectrophotometer and the difference in color was calculated according to the CIE-Lab system. To analyze the data, two-way ANOVA and one-way ANOVA tests of significance were used to compare between the different study groups, followed by pairwise comparisons using post hoc test (Tukey). Results: Different restorative materials showed statistical significance regarding color change after staining (p < 0.001); however, no statistical significance in color change (p > 0.05) was found between the different beverages used. Conclusion: All tested ceramic materials had better color stability compared with composite resin. All the staining beverages used in the current study might cause a significant color change in the tested restorative materials. Clinical significance: The color stability of esthetic restorative materials affects their clinical performance in the oral cavity, where the restorative materials are usually exposed to staining beverages that are frequently consumed by patients. Therefore, it is important to understand the staining effect of the different beverages on esthetic restorative materials.
The effects of children's drinks on the color stability of various restorative materials
The Journal of clinical pediatric dentistry, 2009
To evaluate the effects of exposure to various children's drinks on the color stability of different esthetic restorative material commonly used in pediatric dentistry. Cylindrical specimens (15 x 2mm) were prepared from four different restorative materials (Fuji IX, Fuji II LC, Dyract Extra, and Filtek Z250). For each material, 20 specimens were prepared and divided into four groups. Each group was stored in a different solution (distilled water chocolate milk, cola, grape juice) for 24 hours. A colorimeter was used to measure the color of each specimen both before and after staining. Color change (deltaE*) was calculated, and data was analyzed using two-way ANOVA and Tukey HSD tests. For all restorative materials, the lowest deltaE* values were recorded for specimens stored in distilled water (0.42), followed by chocolate milk (0.88), grape juice (3.45) and cola (3.97). Among the four restorative materials tested, Fuji II LC showed the most color change (3.71) and Fuji IX the ...

The effect of different drinks on the color stability of different restorative materials after one month Objectives: The aim of this study was to evaluate the effect of three different drinks on the color parameters of four different restorative materials. Materials and Methods: Three different composites (Filtek Ultimate Universal Restorative, Filtek Ultimate Flowable, and Filtek Silorane, 3M ESPE) and a polyacid-modified composite resin material (Dyract XP, Dentsply DeTrey GmbH) were evaluated. Eighty-four disc-shaped specimens of 8 mm in diameter and 2 mm in thickness were prepared (n = 21 each). Color coordinates (L*a*b*, ΔL*, Δa*, Δb*, and ΔE*) were measured using a VİTA Easyshade Compact (VİTA Zahnfabrik) after 24 hr of storage (baseline) and after 30 day of storage in three different beverages of black tea, Coca cola, or water (control) (n = 7). In each beverage, the specimens were stored three times a day, one hr each, for 30 day. The color changes (ΔE) were calculated and were analyzed by Kruskal-Wallis and Dunn multiple comparison test. Results: The color difference (ΔE*) of the resin materials ranged between 1.31 and 15.28 after 30 day of immersion in the staining solutions. Dyract XP in Coca cola (15.28 ± 2.61) and black tea (12.22 ± 2.73) showed the highest mean ΔE* value after 30 day, followed by Filtek Ultimate Universal Restorative (5.99 ± 1.25) and Filtek Ultimate Flowable (4.71 ± 1.40) in black tea (p < 0.05). Conclusions: The compomers displayed unacceptable color changes at the end of 30 day in all beverages. Among resin composites, the silorane based composite exhibited relatively good color stability than the others. Filtek Ultimate Universal Restorative and Filtek Flowable showed similar color changes in all beverages.

BACKGROUND: Color mismatch between tooth structure and restoration is a common reason for restoration replacement. This is due, in part, to the diverse chemical structure of both substrates, which display a different staining potential resulting in a significant color mismatch. AIM: The aim of the study was to evaluates the color change of single shade resin composite and compare it to fibrous-filled resin composite (FRc) after storage in coloring beverages. METHODS: Trapezoidal Class V cavities were prepared on the buccal and lingual surfaces of 30 premolars. Cavities on the buccal surface were restored with Omnichroma (ON) and palatal surface with FRc. Specimens were stored on water, tea, and coffee solutions for 24 h and 72 h. The color change was measured after each immersion time and statistically analyzed using three-way analysis of variance (ANOVA) (α = 0.05). RESULTS: Three-way ANOVA showed that different materials had a significant effect on both ΔL and Δa (p < 0.001). F...
Discoloration of different esthetic restorative materials: A spectrophotometric evaluation
2017
Objective: A crucial property of esthetic restorative materials is their long‑term color stability. The aim of this in vitro study was to evaluate the color stability of esthetic restorative materials (one microfilled flowable composite, one nanofilled composite, one nanoybrid composite, one microfilled composite, and one nanoybrid ormocer‑based composite) after surface roughening with cola and exposure to different staining solutions (coffee and red wine). Materials and Methods: All materials were polymerized into silicone rubber rings (2 mm × 6 mm × 8 mm) to obtain 150 specimens identical in size. Seventy‑five specimens of Group A were first exposed to cola for 24 h, and then samples were immersed in coffee or red wine over a 28‑day test period. A colorimetric evaluation, according to the CIE L*a*b* system, was performed at 7, 14, 21, 28 days. Shapiro–Wilk test and Kruskal–Wallis analysis of variance were applied to assess significant differences among restorative materials. Means were compared with Scheffe’s multiple comparison test at the 0.05 level of significance. Results: Specimens of Group A showed higher variations when compared with Group B’s specimens (P < 0.05). After 28 days, the immersion protocols caused a clinically perceivable color change for all materials tested (P < 0.05). Ceram·X Universal and Admira Fusion showed the lowest ΔE variations (P < 0.05). Conclusions: Staining beverages caused significant discolorations for all the materials tested. The first exposure to cola enhanced the subsequent staining with coffee or red wine. Nanohybrid composites reported the lowest color variations.
Background Currently, the demands for restorations have increased considerably; thus, improvements and modifications have been made in dental composite technologies especially using materials that have claimed to improve color stability. Objective This study aimed to determine the effect of restorative materials on dental color stability in vitro using various solutions. Methods In this study, the study samples were composed of 45 discs from different restorative materials (15 micro-hybrids, 15 nano-hybrids, and 15 glass ionomers). These discs were immersed in various beverages an hour a day for one month at room temperature. The color stability was measured using a spectrophotometer before/after immersion (days 7 and 30). Results We realized a significant difference in color change with Coca-Cola and tea after 7 days and 30 days (p < 0.05). However, no significant difference in the samples immersed in DM after seven days and 30 days (p > 0.05) was found. The highest value of ...

Objectives: To evaluate color stability of three different restoratives and efficacy of sonic-brushing in preventing color changes of these restoratives when subjected to coloring agent. Methods: 70 discs (5mm diameter x 2mm thick) made of each tested restorative [Ketak N100 (KN), 3M/ESPE, Beautifil II (BII), Shofu and Filtek Supreme Ultra (FS), 3M/ESPE]. Ten specimens were used as control while other 60 specimens were subdivided into six subgroups (n=10); First, second and third subgroups immersed in cola, coffee and tea respectively for 10 min. 3times daily. Fourth, fifth and sixth subgroups immersed in cola, coffee and tea respectively for 10 min. 3-times daily and brushed with sonic-brush for 1min. after each exposure. Specimens were immersed in artificial saliva between staining and brushing challenges. After a month, all specimens tested for quantitative color changes using Quanta-Environmental Scanning Electron Microscope. Data statistically analyzed using Three-way ANOVA and Tukey's post-hoc test (P≤0.05). Results: The mean color change of non-brush-cycled subgroups (124.1pixel) showed statistically significantly higher values than brush-cycled subgroups (118pixel). BII showed the highest mean color change values (126.4pixel), whereas, no significant difference found between FS (117.4pixel) and KN (120.7pixel). Conclusions: The tested nanoionomer and nanocomposite performed similarly under the test conditions. Brushing specimens after staining improved the color changes of the tested materials.

Color stability evaluation of aesthetic restorative materials
Brazilian Oral Research, 2008
Color match is one of the most important characteristics of aesthetic restorative materials. Maintenance of color throughout the functional lifetime of restorations is important for the durability of treatment. This characteristic is not constant among dental materials. The purpose of this research was to assess the color stability of five aesthetic restorative materials when immersed in a coffee solution. Seventy-one 17 mm x 1 mm specimens, divided into five groups, were made using one direct composite resin (Tetric Ceram®, Ivoclar/Vivadent G1), three indirect composite resins (Targis, Ivoclar/Vivadent G2; Resilab Master, Wilcos G3; belleGlassTM HP, Kerr G4) and one porcelain (IPS Empress® 2, Ivoclar/Vivadent G5). The specimens were immersed in a coffee staining media for 15 days and stored under a controlled temperature of 37°C ± 1°C in the dark. The evaluations were made after 1, 7 and 15 days by means of reflectance spectrophotometry. The data was submitted to two-way ANOVA (p < 0.005) and post hoc tests. Statistical difference was observed between G1 / G3 and the other groups; G2 / G4 and the other groups; and G5 and all the other groups. It was concluded that G1 and G3 showed significantly higher discoloration than the other groups. G2 and G4 showed intermediary pigmentation, while G5 showed the smallest changes.
