Objective: 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. Study Design: Cylindrical specimens(15×2mm) 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 (ΔE*) was calculated, and data was analyzed using two-way ANOVA and Tukey HSD tests. Results: For all restorative materials, the lowest ΔE* 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 least (1.33). There were statistically significant differences among above groups (p<0.05). Conclusions: ΔE* values were acceptable for all materials tested, with the exception of Fuji II LC. Therefore, the use of RMGIC should be avoided in anterior restorations in children due to esthetic reasons.

AbstractIntroductionTemporary restorative materials are widely used, however, little is know about their color stability.Objectiveto evaluate the color stability of the following temporary restorative materials: acrylic and bis-acrylic resins after immersion in pigmenting solutions for different periods of storage.Material and methodFour materials were tested (Dêncor/Clássico, Protemp 4/3M ESPE; Structur 2 SC/Voco; Luxatemp AM Plus/DMG) and 30 test specimens (15 mm in diameter and 2 mm thick) per material were fabricated. They were divided according to the storage medium (artificial saliva, saliva + cola type soda, and saliva + coffee) and storage time intervals (2, 5, 7 and 15 days). Color measurements were made before and after immersions, with use of a spectrophotometer, by means of the CIE L*a*b* system. The data were analyzed by the analysis of variance and the Tukey Test, at a level of significance of 5%.ResultAcrylic resin presented greater color stability in comparison with bis-acrylic resins (p<0.001). When bis-acrylic resins were compared no significant difference was observed between the resins Structur and Luxatemp (p=0.767). As regards solutions tested, coffee showed the highest color change values (p<0.001), and the longer the storage time interval, the greater was the color change in all the temporary restorative materials analyzed (p<0.001).ConclusionAcrylic resin presented greater color stability in comparison with bis-acrylic resins (p<0.001). Coffee caused the greatest color change, and immersion time was determinant in color stability of the temporary materials analyzed.

Objective: To quantify the color variation of two glass ionomer cements and a composite resin used in pediatric dentistry, after being immersed in different pigments agents. Methods: Using two glass ionomer cements (Ketac(tm) Molar and Photac(tm) Fil) and a microhybrid composite resin (Filtek(tm) z250), were produced 40 disks of each material (10 mm in diameter and 2 mm thick). The samples were soaked in artificial saliva (control group), coke, peach Ice Tea(r) and chocolate milk, for 72 hours in an oven at 37ºC. After this period, the samples were washed in 50 ml of distilled water. Finally, using the spectrophotometer, it was made the reading of results. The color change was measured according to the CIE L * a * b * system. Color changes were statistically analyzed using parametric one-way ANOVA and ANOVA with Welch correction, the nonparametric Kruskal-Wallis tests and post-hoc Tukey and Dunnet T3 with p≤ 0.05. Results: The immersion of restorative materials in different pigmentation agents caused a significant color variation on the samples. The agent who presented higher results was the Peach Ice Tea(r). The chocolate milk was the fluid with lowest pigmentation capacity of all restorative materials under study. The greater color variation was found on the Ketac(tm) Molar submerged in Coca-Cola(r) and the smallest on the Filtek(tm) z250 in chocolate milk. Conclusion: All restorative materials were shown to be susceptible to pigmentation by all agents. The Filtek(tm) z250 proved to have better color stability, followed by Photac(tm) Fil and finally by Ketac(tm) Molar.

Objective: This study investigated the effects of three types of mouthwash on the color stability of three resin-based restorative materials (nanohybrid resin composite, sonic-activated bulk-fill material, and compomer). Materials and Methods: To this end, 120 cylindrical disc specimens were prepared and polished, after which they were incubated in distilled water for 24 hours for post-polymerization. The baseline color values of each specimen were measured with a spectrophotometer, then the specimens were randomly divided into four groups. Following immersion in the mouthwashes for 24 hours, the specimens were rinsed with distilled water and dried before the color measurement was repeated. The values of color change (∆E₀₀) were subsequently calculated. A two-way analysis of variance and Duncan’s post hoc multiple comparison tests were conducted to determine statistically significant differences among the restorative materials. Results: All samples showed discoloration after immersion, albeit some instances of discoloration were imperceptible. In this respect, a statistically significant difference was found among the restorative materials and mouthwashes (p<0.05). Imperceptible ∆E₀₀ values were derived on the nanohybrid resin composite and compomer, but perceptible and acceptable ∆E₀₀ values were detected on the sonic-activated bulk-fill materials (p<0.05). The clinically unacceptable discoloration was observed on the sonic-activated bulk-fill composite immersed in Listerine®. Conclusions: Clinicians should make recommendations based on the potential staining capacity of mouthwashes prescribed for daily use in restorative materials. In this way, the need for renewal of restorations due to discoloration could be avoided.

ABSTRACT Objective: The aim was to evaluate the color and surface roughness of nanoparticle (C1) and nanohybrid (C2) composites after immersion in distilled water, acai juice, grape juice and red wine and repolishing. Materials and Methods: After recording the initial surface roughness and color, the specimens were divided into four groups according to the storage solution. The specimens were reassessed after immersion for 1, 2, 4, 8, and 12 weeks and after repolishing. Results: The results showed that after 2 weeks, there were statistically significant changes in color of both resins in all groups, with the exception of the specimens stored in distilled water (P > 0.05). Only 12 weeks of immersion in red wine changed the roughness of composite C1 (P = 0.009). Conclusions: Red wine produced the greatest color change in nanocomposites, followed by grape juice. Acai juice made the color unacceptable clinically only after 12 weeks. Repolishing reduced the color change in all groups.

Aim: The aim of this study is to compare the color stability of different universal composites and to evaluate the effects of keeping them in water for 1 week before coloring. Methodology: Filtek Ultimate (FU), Estelite Ʃ Quick (EQ), and Ceram X One (CX) composites were used. The specimens were kept in the dark, dry environment for 24 hours, then polished, and each composite group was divided into 3 groups: the control, the group that was kept in water for 1 week before coloring and coloring (n=7). The samples in the control group were kept in distilled water for 3 weeks. Samples in the coloring group were colored with coffee for 2 weeks (C), and the samples in the last group were kept in water for 1 week and then stained with coffee for 2 weeks (W+C) (n=7). Color measurements for all samples were taken twice, once before and once after the coloring period. The color changes of the samples were measured using the ∆E* parameter, which was calculated with before and after measurements.  Results: For all composite resins, the ΔE values of the samples in the W+C and C groups were significantly higher than those in the control group. When the composites were compared with each other, the differences between the ΔE values of the composites in the control, W+C, and C groups were not statistically significant. For FU and ESQ, at the end of the coloration period, there were no statistically significant differences between the W+C and C groups. However, for CX, the color change of the samples in the W+C group was significantly higher than that in  the C group. Conclusion: Storage in distilled water for 1 week before staining did not reduce the color change values of the samples. Thus, after composite restorations are performed, there is no need to advise patients to avoid staining foods, especially in the first week after restoration.   How to cite this article: Abdulateef OF, Çobanoğlu N, Gürses M.

OBJECTIVE: Whitening toothpastes are widely used. Hence, it is important to understand their effect on the surface properties of restorative materials. To evaluate the effect of three over-the-counter whitening toothpastes and toothbrushing simulation on microhardness of three restorative materials. Study design: Forty cylindrical (10×2mm) specimens were prepared from each restorative material and randomly assigned into four groups/10 each according to the whitening toothpastes used and distilled water (control). All specimens were measured for microhardness (Baseline–T1). The specimens were brushed with a soft brush using an in vitro tooth-brushing simulator with the assigned whitening toothpaste using the same setting for brushing cycles/load for all groups. Specimens were then measured for microhardness (T2) similar to baseline. Results: The highest (mean±SD) microhardness after application of the whitening toothpastes and brushing was recorded for Intense White and Filtek Z250 XT (127.6±1.8), followed by Optic White and Fuji ll LC (73.9±0.9) and Optic White and Photac Fill (72.7±1.3). There was statistically significant difference for microhardness between pre- and post-application of the whitening toothpastes and brushing for all tested restorative materials (P=0.0001). The microhardness of Filtek Z250XT with 3D White post-application of the whitening toothpastes and brushing was lowest compared to other toothpastes and control (P=0.0001). Conclusion: Microhardness increased after application of the whitening toothpastes and toothbrushing simulation for all combination of tested restorative materials and whitening toothpastes. The microhardness of FIiltek Z250XT with 3D White post-application of the whitening toothpastes and brushing was lowest compared to other toothpastes and control.

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 ofp<0.05.Results.ΔE⁎values were only significantly influenced by restorative material factorp<0.001and varied in the range of 2.08 and 6.55 units for all drugs/restorative materials. The highestΔE⁎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 prominentΔE⁎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 drugsp<0.05. Dolven exhibited significantly higher values compared to Augmentinp=0.021, Macrolp=0.018, and Ventolinp=0.013in 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.

(1) Background: The aim of the paper is to determine how selected staining liquids affect color stability and reflectance of six composite and compomer dental materials. (2) Methods: Six dental materials were chosen for this study: G-aenial (GC), Filtek Z550 (3M), Herculite XRV Ultra (Kerr), Compoglass (Ivoclar Vivadent), Dyract Extra (Dentsply), and Dyract Flow (Dentsply). Ten staining liquids were used (distilled water, tea, tea with sugar, coffee, coffee with sugar, Coca-Cola®, orange and currant juices, soy sauce, and wine). Staining was carried out at 37 °C. The measurements of the color difference (ΔE) and the color parameters were carried out on a Konica Minolta CM5 spetrocolorimeter at different staining times (1, 2, 4, 8, 24, 48, 72, and 168 h). The resulting color change of the dental materials upon staining is presented as plots of ΔE, diffuse-reflection spectra, and Maxwell’s triangle. (3) Results: Significant changes in lightness (ΔL) along with changes in the total color were observed for most materials. Color change was more pronounced in compomers than in composites. (4) Conclusions: Most materials change their color from light cream to light-brown and reddish after exposure to selected staining liquids.

ABSTRACTObjectives: The aim of this study was to evaluate the effects of 3 commercially available mouth rinses on the color stability of 4 different resin-based composite restorative materials.Methods: Forty disc-shaped specimens (10x2 mm) were prepared from each of the following materials: A nanofill composite Filtek Supreme XT (3M/Espe, St. Paul, MN, USA); a packable lowshrinkage composite, AeliteLS Packable (BISCO, Inc, Shaumburg, IL, USA); nanoceramic compositeresin Ceram-X (Dentsply, Konstanz, Germany); a microhybrid composite, and Aelite All-Purpose Body (BISCO). The specimens were then incubated in distilled water at 37°C for 24 hours. The baseline color values (L*, a*, b*) of each specimen were measured with a colorimeter according to the CIELAB color scale. After baseline color measurements, 10 randomly selected specimens from each group were immersed in 1 of the 3 mouth rinses and distilled water as control. The specimens were stored in 20 mL of each mouth rinse (Oral B Alcohol-free, Listerine Tooth Defense Anti-cavity Fluoride Rinse and Klorhex) for 12 hours. After immersion, the color values of all specimens were remeasured, and the color change value ΔE*ab was calculated. Data were analyzed using a 2-way analysis of variance at a significance level of .05.Results: All specimens displayed color changes after immersion, and there was a statistically significant difference among restorative materials and mouth rinses (P<.05); however, the change was not visually perceptible (ΔE*ab<3.3). The interaction between the effect of mouth rinses and type of restorative materials was not statistically significant (P>.05).Conclusions: It may be concluded that although visually nonperceptible, all resin restorative materials tested showed a color difference after immersion in different mouth rinses.

The aim of study was to evaluate the color stability of tooth-colored restorative materials usually used in pediatric dentistry after the application of two plaque disclosing agents. Twenty specimens of each material: a resin-modified glass ionomer, a composite resin and an ion-releasing composite resin, were prepared. Baseline color evaluation was performed, samples were exposed to the plaque disclosing agents: a basic fuchsin solution and a fluorescent dye, and new color evaluations were made. The resin-modified glass ionomer stained with basic fuchsin presented the greatest color change in the present study, and the fluorescent dye did not show statistically significant changes among the restorative materials. In conclusion, basic fuchsin dyes should be carefully used in children with a great number of tooth-colored restorations. J Clin Pediatr Dent 29(2): 143-146, 2005
