“…Alp et al 12 showed that color changes in IPS e.max CAD and Vita Suprinity after applying different surface treatments were clinically acceptable, similar to the present study. Kanat-Erturk 2 found that glazing had lower color change than mechanical polishing and external staining-glazing for IPS e.max CAD and Vita Suprinity ceramics, supported by the results of the current study for EC and VS. Palla et al 13 reported that IPS e.max CAD and IPS e.max Press non-glaze had the lowest E value after the different thermal ageing process compared to other CAD/ CAM ceramics (IPS e.max Press non-glaze and IPS e.max Ceram). In our study, although the color change of the manual polishing group in the LU group was lower than the glazing group, the last color change after the thermal cycle affected the manual varnish and glaze group in a similar way and gave statistically different results from the control groups.…”

“…In literature, various CAD/CAM blocks (IPS emax CAD, IPS emax Press, IPS emax Ceram, Vita Suprinity, Vita Enamic, Vita Mark II and Cerec blocks) have been studied frequently. 2,5,[12][13][14] Aesthetic, smooth and bright surfaces can be achieved with various polishing and final procedures in CAD/CAM restorations. Optiglaze, Vita Akzent Plus, and IPS Ivocolor Glaze systems are the most preferred glazing procedures.…”

The aim of this study was to evaluate the effect of different surface finishing processes on the color stabilities of lithium disilicate glass-ceramics, zirconia-reinforced lithium silicate ceramics, and resin nanoceramics after artificial ageing. MATERIALS AND METHODS. 216 samples were prepared from 3 different CAD/CAM materials (LAVA Ultimate, IPS e.max CAD, VITA Suprinity) with A1 HT color at a size of 14 × 12 mm and a thickness of 0.5 ± 0.05 mm. Color measurements of the samples were performed with a spectrophotometer using color parameters and CIE Lab color system on a gray backing between baseline color and after 5000 cycles of artificial ageing in 4 stages (i.e. the first measurement before the treatment, the second measurement after polishing, the third measurement after cement application, and the fourth measurement after artificial ageing). The results were evaluated using the Variance analysis and Fisher's LSD test. RESULTS. Resin nanoceramics (LU) exhibited higher color change values than zirconia-reinforced lithium silicate (VS) and lithium disilicate (EC) ceramics after artificial ageing. Manual polishing and glazing resulted in similar color change for LU and VS (P>.05). In the EC group, glazing provided statistically different results as compared to the manual polishing and control groups (P<.05). Among the ceramic groups, color change values of the subgroup, which was treated by glazing, of the zirconia-reinforced lithium silicate (VS) and lithium disilicate (EC) samples were below the clinically acceptable level (ΔE < 3.5). CONCLUSION. The lowest color change for all stages was observed in Vita Suprinity.

“…Irrespective of surface treatment, red wine caused higher ΔE 00 values, in line with previous findings in the literature. 24,25 In their study on the discoloration of lithium disilicate ceramic CAD/CAM material in different beverages, Alencar-Silva et al reported that wine caused the highest discoloration. 26 Similarly, in our study, the highest color change among CAD/CAM materials was observed in red wine and later in coffee (P > .05).…”

Objective The improvement of the optical properties of new generation dental ceramics enables more esthetic and durable restorations. This study aimed to investigate the color changes, caused by exposure to different beverages on composite, hybrid ceramic, and zirconia‐reinforced lithium silicate (ZLS) CAD/CAM blocks. Materials and methods CAD/CAM blocks 40 samples (1.5 × 7 × 12 mm) were obtained from each material under water cooling. Following the polishing process and the initial color measurement, the prepared samples were exposed to red wine, coffee, cola, energy drink, and distilled water. Color changes were measured by spectrophotometer at the end of the 1st, 7th, and 30th days. To analyze the color change results, one‐way analysis of variance (ANOVA) test was performed. Results In all restorative material groups, the most prominent color changes were observed on the red wine‐exposed samples, then the coffee‐exposed ones. No significant discoloration was observed on the samples exposed to cola and energy drink, compared to the control group (P > .05). Among the samples exposed to red wine and coffee, the highest discoloration values were observed in composite CAD/CAM material. Conclusions At the end of the 30th day, all materials exposed to wine and coffee showed color change above the clinically acceptable value (ΔE00:2.25). Clinical significance Hybrid ceramic and ZLS CAD/CAM blocks recently used more often by clinicians have shown similar color changes. The results of our study indicate the necessity of choosing esthetic materials according to the dietary habits of individuals.

Objective: To evaluate the effect of two thicknesses of different veneering material on color reproduction of PEEK. Materials and Methods: The samples were divided into three main groups according to their veneering material. Group A: PEEK material veneered with IPS E.max CAD. Group B: PEEK material veneered with Visio.lign resin material. Group C: PEEK material veneered with HIPC. Each group were divided into two subgroups according to veneering material thickness. Subgroup I: veneering material with 0.3 mm thickness. Subgroup II: veneering material with 0.5 mm thickness. The samples were cemented over BioHPP specimens of dimensions 10 x 10 mm and of thickness 0.6mm with clear resin cement and then the color of the cemented samples were examined by Aligent Cary 5000 spectrophotometer. Results: Our study detected that color change were significantly higher in E.max particularly with 0.3 mm thickness and the least color change was Visio.lign particularly with 0.5 mm thickness. Conclusion: 1. The degree of color change of the restoration materials from their selected shade is influenced by the thickness of veneering material. 2. Visio.lign has been found to be most suitable veneering material for veneering of PEEK among this study.
