“…The color stability of the restoration is the most sought-after esthetic property. The degree of discoloration depends mainly on the material composition, solution type and exposure time [ 7 ]. In studies regarding the ceramic color stability, mostly tea, cola, and coffee were used as coloring agents [ 8 , 9 ].…”

Background The aim of this study is to evaluate the color stability of hybrid ceramics stored in different combinations of beverages that are routinely consumed. Methods The specimens were prepared with resin nano-ceramic (Lava Ultimate, 3M Espe, USA) and hybrid ceramic (Vita Enamic, Vita Zahnfabrik, Germany). The specimens were aged in a thermocycler machine for 10,000 cycles. They were stored in different combinations of beverages (water, tea, coke, coffee, red wine, pomegranate juice, and turnip juice) for 12 + 12 h. Surface roughness measurements were performed using a profilometer. The specimen colors were measured using a spectrophotometer. The color values (L-a-b) of the specimens and mean surface roughness values (Ra) were recorded at the end of the 1st (D1), 7th (D7), 14th (D14) and 28th (D28) d. Results When the solution groups were examined, significant color changes were observed in the Lava coffee-tea, Enamic coffee-tea, Lava coffee-wine, and Enamic coffee-wine groups compared with the other groups (p < 0.01). Except for the samples in the Lava coffee-wine 28th day (D28) and Enamic coffee-wine 28th day (D28) groups, more color changes were observed in the Lava samples than in the Enamic samples across all groups and periods. Conclusion Greater color changes (except for the samples stored in coffee-wine) were observed in the Lava samples than in the Enamic samples across all groups and periods. It was observed that the coffee-tea and coffee-wine beverage combinations produced the greatest color change in hybrid ceramics within the limitations of this study.

“…Green tea, coffee and Coca-Cola are the most regularly consumed acidic drinks in daily life. Green tea and coffee have a pH of 5.8 and consist of caffeine, tannates, citrates and chlorogenic acid, whereas Coca-Cola has a pH of 2.5 and is made up of phosphates, carbonated water, and caramel [ 47 , 48 ]. Staining of ceramics caused by these low-pH acidified beverages may compromise the cosmetic outcome [ 49 – 51 ], thereby reducing durability of the material, resulting in roughness, abrasion, and subsequent staining of teeth, ultimately causing patient dissatisfaction [ 52 ].…”

“…However, other studies evaluated the color porcelain materials stability concerning the surface texture, concluding that accurate polishing procedures could create smooth ceramic surfaces similar to glazed surfaces [ 51 , 53 ]. Glazing has been found to produce smoother surfaces than glass ceramic polishing [ 48 ]. Manufacturers also advocate glazing or polishing to improve the aesthetics of lithium disilicate [ 24 ].…”

Background The majority of dental professionals currently recognize lithium disilicate E-max ceramic veneers as a the most widely used, conservative, and effective cosmetic materials in dentistry. This study aimed to compare the degree of surface changes – roughness (Ra), depth (Rz), and mean color changes (Δ E 00 ) – of computer-aided design-computer-aided manufactured (CAD/CAM) ceramic veneers materials of varying thicknesses caused by staining by green tea, coffee, and Coca-Cola using digital spectrophotometer. Material/Methods This study was conducted at King Khalid University, College of Dentistry. Lithium disilicate glass ceramic (LDGC) material was used to create 60 rectangular slices using the CAD/CAM system. The material thickness and the type of beverage were measured. The specimens were immersed in beverages according to the manufacturer’s instructions. Specimen description and tomography were completed with a 3D noncontact surface metrology using interferometry. The “VITA Easy-Shade” spectrophotometer was used to measure Δ E 00 . It was recorded after 2 weeks for different material thicknesses after immersing samples in green tea, coffee, and Coca-Cola staining materials. Results Significant changes in ceramic thickness were found in Ra and Rz of 0.07 and 1.00 mm after 14 days of staining. Coca-Cola showed a significant difference in Ra and Rz with 1.00 mm thickness measurement compared to the 0.07 mm group with ≤ of 0.05, which was considered statistically significant. Highest Δ E 00 were recorded among samples stained by Coca-Cola, followed by coffee, for both thicknesses. Conclusions Those findings support previous studies using spectrophotometric analysis of staining of CAD-CAM ceramic veneers that Coca-Cola followed by coffee resulted in the greatest color Δ E 00 change.

“…Based on a previous study Alsilani et al 35 , it was found that a sample size of 18 per group possess an 80% power to detect an increase of 0.50 with a significance level (alpha) of 0.05 (two-tailed) and 95% confidence intervals. In 80% the power of those experiments, the P value will be less than 0.05 (two-tailed) so the results are to be considered "significant statistically".…”

Statement of the Problem: Alterations of pH in the oral cavity can lead to degradation of machinable esthetic materials that mimic the natural tooth appearance resulting in an esthetic failure. Hence, the stability of the optical and mechanical characteristics of these materials is essential for a long-term successful restoration.Aim of the Study: To evaluate the translucency, microhardness, and fracture toughness of two CAD/CAM materials (IPS e.max CAD and Vita Enamic) after immersion in two acidic beverages (Coffee and Coca-Cola).Materials and methods: A total of 36 samples were equally divided into two groups each (n=18) as follows, Group I: IPS e.max CAD and Group II: Vita Enamic. Each group was further subdivided into two subgroups (n=9) according to the acidic beverage used, either Coffee, or Coca-Cola. Samples were immersed in acidic beverage solutions for three weeks, after which all samples were subjected to measure the translucency parameter using a Reflective Spectrophotometer and then using Vickers Micro-Hardness Tester to measure surface microhardness and fracture toughness. Statistical analysis was performed using one-way analysis of variance followed by Tukey's posthoc test if showed significance. Student t-test was done between main groups, while Two-way ANOVA compared the effect of each factor.Results: There was a statistically significant difference between IPS e.max CAD and Vita Enamic regarding translucency. Significant difference in surface microhardness, and fracture toughness after immersion in two acidic beverage solutions was revealed.Conclusions: Acidic beverages can adversely affect the translucency of glass-ceramic and hybrid ceramic materials. Microhardness and fracture toughness of different CAD/CAM esthetic materials was negatively affected secondary to exposure to beverages with low pH values.
