“…Therefore, the first null hypothesis that the color stability of composite block, nanohybrid, and microhybrid resin composites would not be different was rejected. The result is in agreement with previous studies, which have concluded that the indirect composite blocks had lower color change values than direct resin composites (3,19).…”

“…This result is in agreement with previous studies in which the repolishing provided a significant improvement in the discoloration of resin composites (5,16,18), ceramics, and resin-based composite blocks (9). In a previous study, repolishing did not affect the color change of the composite block Cerasmart, and this was attributed to a low discoloration degree (19). Nonetheless, internal discolorations may not be completely removed by repolishing (9,30).…”

“…In the clinical environment, the discoloration potential of restorative materials might be influenced by different factors, including saliva, oral temperature, tooth brushing, toothpaste, and diet content (9). Moreover, the geometrical shape of the specimens is not similar to typical dental restorations (19). Thus, more in vitro and clinical studies must be conducted to assess the color stability of the materials.…”

“…The indirect restorations might currently be preferred for appropriate indications since they have higher mechanical properties and discoloration resistance than direct composite restorations ( 4 ). However, there are a limited number of studies that have comparatively evaluated the color stability of indirect composite blocks and direct resin composites and the influence of repolishing on the color change ( 3 , 19 ). Therefore, the aim of the current study was to comparatively assess the color stability of composite block, nanohybrid, and microhybrid resin composites after immersion in red wine and repolishing.…”

PurposeTo comparatively assess the color stability of indirect composite block, nanohybrid, and microhybrid resin composites after immersion in red wine and repolishing. Materials and MethodsSpecimens (2x7x12 mm) were prepared using an indirect composite block (Cerasmart), a nanohybrid (Ceram X), and a microhybrid (Charisma Smart) resin composite. The specimens' color was recorded based on the CIE L*a*b* system in a spectrophotometer (Spectroshade). After recording the initial color, the specimens were immersed in red wine for 3 hours per day for 15 days. The color measurement was done again. The specimens were repolished with a multistep polishing system (SuperSnap). The color was measured for the third time. The color change values (ΔE) were calculated with the L*, a*, and b* coordinates obtained at baseline, after the immersion procedure, and after repolishing. Statistical analyses were performed with one-way ANOVA, Tukey's post hoc, and paired t-tests (p=0.05). ResultsThe composite block presented the lowest ΔE value (p<0.05). No statistically significant difference was found between the ΔE values of the nanohybrid and microhybrid resin composites. The repolishing promoted a decrease in the color change of all three materials (p<0.05). The ΔE value of the composite block was clinically acceptable after repolishing. ConclusionThe composite block showed higher color stability. The staining resistance of the nanohybrid and microhybrid resin composites was not different. The repolishing decreased the discoloration of all three materials.

“…Depending on the developments in computeraided design and manufacturing (CAD / CAM) technology, resin-containing CAD / CAM blocks have been introduced to the market. While these materials, which are used by indirect methods, are advantageous because of the advantageous properties of ceramics, such as durability and color stability, and superior physical properties of composite resins, such as improved bending and low abrasiveness (3), the fact that composite resin formulations have a much higher potential to be stained than ceramic due to temperature changes in the oral environment and coloring beverages, can also be seen as a disadvantage (4).…”

Aim: Resin-containing restorative materials are widely used in the restoration of teeth. Our aim in this study is to examine the color change of beverages consumed cold on resin-containing restorative materials. Methodology: Samples were prepared using composite resins and resin-based CAD/CAM blocks. All prepared samples were kept in cold tea, cold coffee, coke, energy drink, and distilled water after polishing. The color values of the samples were measured with a spectrophotometer at the beginning, on the 1st, 7th and 30th days, and the color change values were calculated with the CIEDE2000 formula. Statistical analysis of color change values was performed using two-way analysis of variance (ANOVA) and Tukey multiple comparison tests (p<0.05). Results: While there was no statistically significant difference in the color changes of the resin-containing dental materials at the end of the 1st day (p>0.05), at the end of the 7th and 30th days, cold tea caused the statistically highest color change (p<0.05). There was no statistically significant difference between the color change values of cold coffee, coke and energy drink on the materials in all time periods (p>0.05). Composite resins showed more color change than resin-based CAD/CAM blocks (p<0.05). Conclusion: Cold tea causes the most discoloration on resin-based materials. While the resin-containing CAD/CAM blocks showed a color change under the AT value in all cold drinks, the composite resins showed a color change above the AT value in cold tea and coffee.

Laminate veneer is a treatment in prosthodontic that is aesthetically pleasing and requires minimal preparation that can be fabricated with indirect resin composite, which is durable and low-cost, though this material has poor color stability. Due to the increasing consumption of black tea and apple juice, there was a need for this study to be taken out. This study aims to determine the effect of consumption of black tea and apple juice on colour stability. Indirect resin composite specimens were fabricated 20 mm in diameter and 1.5 mm in thickness and divided into 3 groups (n = 10). Specimens were immersed in 3 types of solutions: black tea, apple juice and aquadest as control. The color of specimens was measured before and after immersion using a color spectrophotometer. Statistical analysis was performed with univariate test, Mann-Whitney U test, Independent T-test, one-way ANOVA and LSD test. Mean delta E (ΔE) value for black tea is 1,381 ± 0,938 and ΔE = 6,803 ± 1,757 in apple juice. Black tea and apple juice reduced the color stability of indirect resin composite significantly with p = 0,001 (p < 0.05). The effect of immersion in both drinks differed significantly with p = 0,001 (p <0.05). Apple juice experienced the greatest reduction in color stability, followed by black tea, and lastly the control group. The difference in the effect of immersing black tea and apple juice was due to the difference in pH and major acid content.
