“…A similar study done by Yu et al 27 on polymer infiltrated ceramics and their wear behavior concluded that acid erosion decreased the surface microhardness and increased surface roughness and it is in favor with the present study. The results of the present study are supported by the studies conducted by Denry et al, 28 Eleana et al, 29 and Vechiato-Filho et al 30 A study done by Al-Hiyasat et al 31 is similar to the present study and also in favor which concluded that Coca-Cola not only contributed to the enamel wear by demineralizing the tooth and making it susceptible to the abrasive effect of the ceramic materials but also effected the wear of the ceramic material.…”

Aim:The aim of the present study was to evaluate the effect of acidic agents on microhardness and surface morphology of two metal ceramic materials at various intervals. Materials and methods: A total of 120 metal ceramic disks were prepared and divided into two categories with 60 each. Each category was divided into two groups, group I (Made of IPS d.SIGN) and group II (made of VITA VMK), containing 30 samples each, which was subdivided into three subgroups each containing 10 samples A(i) B(i) acting as control, A(ii) B(ii) immersed in 0.5% HCl, and A(iii) B(iii) immersed in soft cola drink. Group I was tested for microhardness with Vickers microhardness testing machine at an interval of 0 minute, 24 hours, and 168 hours after immersing in acidic agents. Group II was observed for surface morphology changes with scanning electron microscope before immersion, and at an interval of 24 hours and 168 hours after immersing in acidic agents. The results were analyzed statistically, tabulated, and compared. Results: Results revealed that there was a significant decrease in microhardness of IPS d.SIGN and VITA VMK when immersed in acidic agents at an interval of 0 minute, 24 hours, and 168 hours. There were significant surface morphological changes too of both the ceramics before and after immersing in acidic agents at 24 hours and 168 hours. Conclusion: Acidic agents evaluated in the present study affected microhardness and surface morphology of both the ceramics, and IPS d.SIGN is the most suitable and would be recommended in people who consume acidic beverages. Clinical significance: Durability of dental ceramics is very good, but degradation occurs when exposed to acidic agents. All the properties of ceramics are to be known in depth as they are widely used to construct various types of prostheses, and this has to be considered especially in people who consume acidic foods and drinks.

Computer-aided design/computer-aided manufacturing (CAD/CAM) materials were submitted to thermocycling, to identify changes in mechanical behavior. Four CAD/CAM materials were divided in four subordinate groups (n=9): (1) dry out for 7 days, (2) distilled water at 37 o C for 7 days, (3) 60,000 thermocycles, and (4) 120,000 thermocycles. Following thermocycling, samples were submitted to three-point bending test. Two-way ANOVA and post-hoc Tukey's test were performed (α=0.05). The IPS e.max CAD had a flexural strength of 396±75 MPa and flexural modulus of 84±11 GPa, followed by Vita Enamic with values of 153±17 MPa and 28±5 GPa respectively. The flexural strength recorded for Lava Ultimate was 149±28 MPa and the flexural modulus was 12±3 GPa. Vitablocs Mark II had the lowest flexural strength values (125±10 MPa) and a flexural modulus of 49±15 GPa. Although polymer-based materials have similar mechanical properties compared to ceramics, they are affected by thermo cycling conditions.

“…The absorption features of the resin allow the acid to attack the bond between glass particles and the polymer, leading to the disintegration of the polymer and degradation of the ceramic, leaving a rough surface behind, which adversely affects the color and light reflection of restoration (15,20,38) .…”

Objective: The purpose of this study was to evaluate the effect of simulated gastric acid on the color and translucency of monolithic ceramics. Materials and Methods: A total of forty ceramic disks made from four ceramic materials (10 each) were cut with a final thickness of 1.0 mm using Isomet saw from ceramic blocks of each material (Ceramil Zolid fx white [Z], IPS e.max CAD [E] HT A3, Vita Suprinity [S] HT A3, and Cerasmart [C] HT A3). Zirconia disks were then colored using A3 coloring liquid and sintered, while IPS e.max CAD and Vita Suprinity were crystallized according to their manufacturers' instructions. A spectrophotometer was used to evaluate color change (∆E) and translucency parameter (TP). L*a*b* color coordinates were determined over white and black backgrounds according to the CIE Lab 1976 color scale before and after immersion in simulated gastric acid (HCl) for 96 h at 37°C incubator. Collected data were statistically analyzed using ANOVA followed by Tukey's posthoc test and the significance level was set at P≤0.05. Results: The highest color change was recorded for group C followed by group E, group S, and the least change was with group Z. Translucency increased significantly (P˂0.05) after acid immersion for all materials except for group C. Conclusion: Zolid fx showed the greatest color stability after gastric acid immersion, while Cerasmart is the least one, however, all tested ceramics are within the clinically acceptable limit. Translucency increased after gastric acid immersion for all tested ceramics except for Cerasmart, it decreased.
