“…Among all, ceramics based on lithium disilicate or feldspar which are highly dense materials showed the best color stability. These results are in accordance with previous studies 1,4,5,10) . It was shown that the organic matrix is mainly responsible for discoloration.…”

“…This protocol was followed since previous research demonstrated that within this time interval composites take up significant staining. This immersion time is equivalent to seven months of coffee drinking 10,29,30) . For the bleaching procedures, an at-home bleaching protocol with 10% carbamide-peroxide was used as it is one of the most accepted bleaching treatment by patients, with the least side effects 31) .…”

“…Consequently, when exposed to various liquids in the oral cavity these materials can suffer a discoloration process. Red wine, coffee, tea, and chlorhexidine are known to have a discoloring effect on resin restorations 10) . Since color change of resin restorations over time is inevitable, many attempts have been put to improve the altered esthetic appearance of these restorations.…”

The aim of the study was to assess the effect of staining and bleaching on CAD/CAM materials with high (HT) and low translucency (LT or T). Samples were stored in coffee and subsequently bleached. CIELAB parameters were recorded at baseline, after coffee immersion, after bleaching. Translucency parameter (TP), whiteness index (WID) and color changes were calculated (ΔE00). Influence of staining and bleaching was analyzed with repeated-measures ANOVA and color differences between materials were analyzed with one-way ANOVA (α=0.05). Staining and bleaching significantly affected CIELAB parameters and WID for all materials (p<0.001). TP was significantly influenced by staining and bleaching for Crios and Enamic (p<0.05). Mean color differences were significantly different between materials (p<0.001). The greatest color changes due to staining were observed for Lava Ultimate while the lowest for e.max CAD. Both coffee staining and bleaching induced greater color changes for HT materials of the same brand compared to LT.

“…In this case the outer enamel layer translucency was measured to study its translucency at different thicknesses and its effect on the overall color of the final restoration. 10 In each specimen the translucency was measured by placing each specimen once against black background and once against white background. Three measurements were taken.…”

The purpose of this study was to calculate and study the color components (Chroma and Value) and translucency of resin composites at different thicknesses. Method: resin composites shade A1 were used in this study; Filtek Z350 XT 3M (FT), Harmonize Kerr (HK), and Empress Direct Ivoclar Vivadent (ED). All samples were fabricated with same dentin thickness of 2mm, while the enamel samples were prepared in two thickness; 0.5mm and 1mm. Transparency parameter evaluation was done by measuring the CIELAB parameters of each sample once against white background and once against black. ∆E was used to evaluate the change in color of composite resin at different thicknesses. One-way ANOVA and Tukey HSD test were used to analyze the descriptive statistics. Pearson correlation coefficient was used to conclude a relation between thickness and chroma; and thickness and value. Results: There was a significant difference in translucency in all composite groups at enamel thickness 0.5 and 1mm. ∆E showed significant difference when comparing group FT with ED and HK, but no significant difference when comparing groups ED and HK. As for chroma, groups ED and FT showed a decrease in chroma as thickness increased and the results were significant at (p<0.05), while groups HK showed increase in chroma but the results were insignificant. Conclusion: As thickness increases the translucency and chroma of the composite resin decreases.

The aim of this in vitro study was to investigate the effect of frequently consumed beverages on the color stability and surface properties of direct and indirect dental composite materials. The two dental composite materials (direct and indirect) and four beverages (distilled water, tea, coffee, cola) were assessed. The specimens were prepared for evaluating monomer conversion, water sorption, and color stability (n = 10) and taking scanning electron and atomic force microscopy images (n = 3). The data were analyzed using independent t‐test, Mann‐Whitney U test, two‐way analysis of variance, and Spearman's correlation (P < .05). Indirect dental composite materials had better monomer conversion, color stability, and surface roughness value when compared to direct dental composite materials (P < .001, P = .002, P = .002, respectively). The control group had lower ΔE00 values when compared to the tea (P < .001) and coffee (P < .001) groups. There was a negative correlation between monomer conversion and surface roughness (r = −0.481, P = .032). Color stability and surface roughness value of direct dental composite materials differed from indirect dental composite materials after immersed in different beverages. The tested beverages significantly influenced color stability.
