“…In this study, the red wine was chosen as a staining agent because of its high concentration of pigment molecules, alcohol content, and low pH, which can explain the discoloration observed in resin‐based materials in previous studies. Alcohol is a solvent that has an effect on the degradation of the organic matrix of resin‐based materials . The storage in red wine itself does not simulate what happens in clinical situations, since there is also abrasion caused by tooth brushing or oclusal contacts, and this can be considered a limitation of the present study, but the present study aimed to evaluate the degradation caused without the interference of abrasion of the coating materials.…”

“…The longevity and esthetic appearance of tooth‐colored restorations depends on the material's susceptibility to staining 32 . Although hybrid ceramics have been extensively studied, 40‐70 the information available about the optical characteristics of contemporary CAD/CAM PICN materials is limited.…”

Purpose To investigate and compare the translucency and color stability of a newly introduced polymer‐infiltrated ceramic network (PICN) material (Crystal Ultra) to those of clinically well‐established restorative materials. Materials and Methods A total of 80 specimens measuring (12 × 14 × 1 mm ± 0.05 mm) were prepared from five CAD/CAM (IPS e.max (IPS), Lava Ultimate (LU), Cerasmart (CS), Vita Enamic (VE), Crystal Ultra (CU)) high translucency (HT) blocks in A2 or equivalent shades. Specimens were randomly allocated into two groups (A and B) (n = 8), and were subjected to 5,000 thermal‐cycles (TC). This was followed by one‐week immersion of group A specimens in coffee (staining) solution and group B specimens in distilled water. Following immersion, the specimens from both groups were further subjected to 5,000 TC. A spectrophotometer was used to measure the translucency parameter (TP) and color change (ΔE00) of the samples using CIELAB color coordinates at baseline, after 5,000 TC, following immersion, and after further 5,000 TC. Color stability was evaluated using the CIEDE2000 formula. Data were analyzed by non‐parametric tests (α = 0.05). Results The TP values of the CAD/CAM materials ranged from 18.0‐22.0. Following the initial TC, the changes in TP values were significant for VE (p = 0.012). Coffee immersion and further TC significantly impacted the TP values of PICN (VE and CU) materials compared to glass‐ ceramics (IPS), and resin nanoceramic (CS and LU) materials (p = 0.012). The comparison between CAD/CAM materials at different intervals showed a significant difference in the TP values (p < 0.01). The materials showed perceptible color changes following the initial TC except for PICN materials which demonstrated acceptable color changes. The major color difference was noticed for the resin nanoceramic specimens immersed in coffee; LU and CS showed higher color changes (ΔE00 = 2.45 and 2.09, respectively) than VE and CU (ΔE00 < 1.8). Conclusions The translucency of the newly introduced Crystal Ultra PICN material was low compared to the resin nanoceramics and lithium disilicate glass‐ceramic. The Crystal Ultra material exhibited better color stability compared to resin nanoceramics, but higher color change when compared with Vita Enamic PICN and lithium disilicate glass‐ceramic CAD/CAM materials.

“…Higher TP values were reported for RNC materials, such as Shofu HC, Lava Ultimate and Cerasmart, compared to other materials (27)(28)(29). Conversely, similar TP values between RNC and PICN have been reported (11). It can be hypothesized that similar refractive index between the inorganic filler and the organic phase in RNC contributes to this result.…”

“…Finishing and polishing affect the surface texture and roughness (9-10), which associated with in-mouth material aging and consumption of dark colored beverages, such as coffee, tea, red wine, and coke can provoke alterations in color and in translucency parameter (TP) of restorations (11)(12)(13)(14)(15)(16)(17). In vitro tests can be used to compare different materials under the same conditions and to predict the clinical performance (18).…”

Učinak bojenja i starenja na parametar translucencije CAD/CAM materijala UvodUvođenje u protetiku sustava za računalno potpomognuti dizajn/računalno potpomognutu proizvodnju (CAD/ CAM) omogućilo je bržu izradu zubnih nadomjestaka veće mehaničke čvrstoće u usporedbi s ručno izrađenim keramičkim nadomjestcima (1). Potpuno digitalizirani proces u ordinaciji integriran je u svakodnevnu praksu -od intraoralnoga 3D skeniranja do izrade nadomjestaka CAD/CAM tehnologijom, jer štedi vrijeme, smanjuje pacijentu broj posjeta ordinaciji i eliminira potrebu za dentalnim tehničarom (2 -3).
