“…These findings coincide with other studies that conclude that zirconia reinforced lithium silicate glass-ceramic revealed higher mechanical properties compared with lithium disilicate glass-ceramic 26 . On the other hand, unlike this study, Cruz et al (2019) 27 found that simulated gastric acid significantly changed surface roughness of vita suprinity. This may be attributed to that they tested the specimens without glazing.…”

“…These findings are similar to another study by Alnasser et al (2019) 14 that found significant increase in surface roughness for hybrid ceramics. Cruz et al (2019) 27 reported a significant decrease in surface roughness after gastric acidic challenge for Vita enamic, which was not found in the present study. According to Cruz et al (2019) 27 , the decrease in its roughness was possibly due to the dissolution of the ceramic portion that constitutes most of this material.…”

Purpose: The purpose of this in vitro study was to evaluate the effect of simulated gastric acidity on surface roughness of different types of dental ceramics. Methods: Fifty specimens were divided according to type of the material into five groups (n=10), as follows: Partially stabilized zirconia (PSZ) (Prettaue), Fully stabilized zirconia (FSZ) (Prettaue Anterior), lithium disilicate ceramics (IPS. Emax), Zirconia-containing lithium silicate ceramics (ZLS) (Vita Suprinity) and Hybrid ceramics (Vita Enamic). Specimens were cut using a low-speed diamond saw (Isomet) into a rectangular shape with the following dimension: 12mm width x 14mm length x 1 mm thickness. Surface roughness was evaluated by optical profilometer. Each specimen was immersed in 5 ml of the simulated acid of ph 1.2 for 96 h in a37˚C incubator. Surface roughness of all tested groups was revaluated. One-way ANOVA was used to compare mean difference between groups. Paired t-test was used for comparing (before and after) roughness in each group. Results: There was significant difference (P=0.002) between all groups. There was increase in surface roughness for all materials tested, but it was non-significant (P>0.05) for Prettaue (P=0.607), Prettaue Anterior (P=0.273) and Vita Suprinty group (P=0.201). There was significant increase (P≤0. 05) for IPS. Emax group (P=0.007) and Vita Enamic groups (P=0.021). Prettaue Anterior group showed the least amount of surface roughness change (0.0006±0.002), while Vita Enamic group showed the highest surface roughness change (0.0100±0.011). Conclusions: The gastric acid significantly increased the surface roughness of hybrid ceramics and lithium disilicate ceramics.

“…Cruz et al (32) stated that the increase in surface roughness of Vita Enamic with exposure to strong acids was possibly due to the dissolution of the ceramic portion that constitutes most of this material. The boundaries between the ceramic and polymer portions became more evident with the dissolution of the feldspathic matrix by the acid.…”

Objective: The objective of this study was to evaluate the effect of different pH media on color stability, translucency and surface roughness on Hybrid ceramic material (Vita Enamic) and bilayered reinforced polymer (PEEK). Materials and methods: A total of 60 discs, 30 in each group that were designed with milled with CAD/CAM, each group was further subdivided into 3 subgroups (10 samples in each group) according to the immersing solution.(neutral, weak acid and strong acid), all samples were aged in the immersion solutions for 24 days in an incubator at 37 o which simulate 2 years of clinical service. Optical profilometer was used to assess surface roughness, a spectrophotometer was used to assess color change and translucency was calculated with the tranclucency parameter equation. Results: The results showed that no statistical significant difference in surface roughness, color stability and translucency with Vita Enamic in different solutions, and statistical significant difference with PEEK group in different solutions. Conclusion: Vita Enamic has higher color stability and translucency than PEEK and can maintain smoother surface with different pH media.

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.
