“…Surface treatments and aging modified the behavior of chroma and hue in the resin tested, especially in the NP group, in which the specimens became more yellowish. Other studies also found changes in the L*a*b* colorimetric patterns associated with aging, type of polishing performed, and presence of water inside the material …”

“…Although the immersion for longer periods of time does not represent a clinical situation, this method provides a better understanding of the staining potencial of several solutions and color stability of materials subjected to immersion. Other studies used this method to verify color stability of materials [10][11][12][13] . In the present study, immersion in water and cola-based soft drink caused changes in color of both materials studied, however, the color changed was significantly higher for the cola-based drink.…”

Aims: The objective of this study was to evaluate the mechanical properties of two bis-acryl interim resin materials, such as color stability, flexural strength and shear bond strength to flowable composite resin, simulating clinical situations when this material has to be used for repair as add-on. Two shades of two bis-acryl interim resin materials [Structur 2 SC (shades Bleach and A2); Protemp 4 (shades A1 and A2)] were evaluated. Discs (5 x 1 mm) were fabricated and baseline color was determined after 1 h. Ten specimens were immersed at 37 o C in solutions of distilled water (control) and cola-based soft drink (Coca-Cola). Color measurements were performed with a spectrophotometer using CIELab parameters. Color readings were again measured after 2 hours, 4 hours, 24 hours and 7 days. Flexural strength was determined using the three-point bending test (10 x 1 x 2 mm) on a universal testing machine (0.5 mm/min) (n = 10). Discs of bis-acryl resin were embedded in acrylic resin, planned and distributed in 2 groups: G1 -Filtek Z350 Flow/Protemp4 and G2 -Grandio SO Flow/Structure 3 (n = 15). Cylinders (3.5 x 2 mm) were made with the flowable composite resins and polymerized for 20 s. The specimens were stored in distilled water at 37 o C for 24 h and subjected to shear bond strength test. Data were analyzed using one-way ANOVA and Tukey's test (α = 0.05

“…On the other hand, there are several opinions in literature about the threshold value for a clinically acceptable and visual color difference. This value is reported over 3.33 (6,9,10,17,25), 3.5 (13,19) or 3.7 (23). The authors adopt the threshold value of 3.5 for clinically accepted color difference when interpreting the results of this study.…”

Bulgular: En düşük ΔE değeri grup 1'de gözlendi. Grup 2'de, grup 3'e kıyasla daha yüksek ΔE değeri elde edilse de her iki grup arasında istatistiksel olarak anlamlı fark bulunamadı.Sonuç: Yarı saydam baz ve yarı saydam katalizör karışımı sonucunda klinik olarak kabul edilebilir bir renk değişimi gözlenirken, B1 baz, A3 katalizör ve A1 baz, A3 katalizör karışımları ise klinik olarak kabul edilebilir değerlerin üzerinde renk değişimi göstermiştir. Rezin simanın rengi simanın renk stabilitesi üzerinde kısmen etkili olmuştur. Objective:The aim of this study was to determine effect of shade selection on resin cement's color stability. MaterialsandMethods:Ten resin cement samples in dimensions of 10 mm diameter and 2 mm thickness for each group [group 1: Translucent base and translucent catalyst, group 2: Bleach XL (B1) base and yellow (A3) catalyst, group 3: White (A1) base and A3 catalyst] totally 30 samples were prepared. Color coordinates of each sample were recorded after polymerization and 5000 thermal cycles. Color variation (ΔE) was calculated for each sample and statistical analyses were performed. Results:The lowest ΔE values were obtained for group 1. Group 2 showed higher ΔE values than group 3 however there were no statistical difference. Conclusion:Translucent base and translucent catalyst mixture showed clinically acceptable color stability while B1 base and A3 catalyst and A1 base and A3 catalyst mixtures did not show clinically acceptable color stability. Shade of the resin cement partially effected its color stability.Ad dressforCor res pon den ce/Ya zış maAd re si:
