Summary: The study found that the color of the three tested lithium disilicate ceramic materials was affected by additional pressing, with only LDS-HDM showing color changes below the clinically perceptible threshold. Furthermore, only LDS showed a significant decrease in translucency after additional pressing.

Summary: This study compared the load-to-failure resistance and optical properties of nano-lithium disilicate (NLD), lithium disilicate (LDS), and zirconia-reinforced lithium silicate (ZLS) in different aging processes. The results showed that ZLS had the highest load-to-failure resistance, while there was no significant difference between LDS and NLD. The interaction between material type, thickness, and thermocycling affected the color difference and relative translucency parameter.

Summary: This study investigated the effects of different breeds, finishing feeds, and retail packaging methods on the quality of sheep meat. The study found that packaging had the greatest impact on color, texture, and oxidative stability. Supplementing feed with camelina forage or meal and reducing oxygen levels in retail packaging were recommended to enhance the quality of sheep meat.

Summary: This research focuses on comparing newly emerging alloy target-based ternary PVD-coated tool inserts with non-alloy target-based binary and ternary-coated tool inserts for the dry finishing of AA7075. The performance of these inserts in terms of tool life and surface roughness is analyzed using experimental design and statistical analysis. The optimized solution for TiN-coated tool inserts is obtained through full factorial experimental configuration, providing higher surface finish, longer tool life, and higher material removal rate compared to other coatings.

Summary: This study evaluated the changes in translucency, contrast ratio, and color of CAD/CAM zirconia after accelerated artificial aging at different sintering temperatures. The results showed that an increase in sintering temperature led to an increase in translucency, while contrast ratio and color change were not significant.

Summary: This study evaluates the effects of accelerated aging on the discolouration of surface-treated spruce and oak wood coated with solvent-based polyurethane lacquers, as well as spruce wood coated with water-based coating systems. The results show that the aging process significantly induced discolouration in the wood surfaces, and that factors such as wood species, lacquer/coating system type, lacquer modification, and wood pre-treatment with pigment and stain mordants had significant impacts on colour stability.

Summary: This study aims to evaluate the effect of different curing protocols on the color stability and translucency of resin luting agents. The results suggest that, except for one material, the curing protocol does not affect the color and translucency of the tested resin luting agents.

Summary: The study measured the effect of simulated aging on stained resin-ceramic CAD/CAM materials in terms of color and gloss durability. Results showed significant changes in color and gloss after aging, with increases in gloss for the LVU group and decreases in gloss for the ENA, CER, and VM2 groups. This indicates a notable impact of aging on the properties of these materials.

Summary: Laser texturing can improve the tribological performance of a surface. In this study, a grid-texture composed of micro-channels was fabricated on a zirconia surface using nanosecond laser. The influence of laser parameters on the morphology and geometry of the micro-channels was investigated to obtain high-quality microchannels. The results showed that laser power had minimal effect on the taper angle and height of pile up. Chemical analysis indicated that laser irradiation caused a deoxidation reaction, resulting in decreased oxygen vacancies and darkening of color, which could be reduced through annealing treatment. Phase analysis revealed that internal stress caused by reduced oxygen vacancies led to a transformation from tetragonal to monoclinic phase. The grid-textures composed of micro-channels with better quality obtained from experimental results were found to alter the tribology of zirconia. Wear tests showed that the coefficient of friction for the laser-treated surface was higher and more stable compared to the untreated surface. The observation of worn surface revealed lower adhesion of lamellar structures on the laser-treated surface and the presence of abrasive particles in microgrooves created by laser, which reduced ploughing effect and improved friction stability.

Summary: The study aimed to analyze the color differences between milled veneers fabricated with different CAD-CAM ceramic materials and natural teeth. Results showed significant effects of different ceramic materials on the hue of milled veneers, but not on the lightness values; the color of the milled veneer was able to match that of the natural tooth.

Summary: This study aimed to evaluate the color stability of hybrid ceramics stored in different combinations of beverages. It was found that coffee-tea and coffee-wine combinations had the greatest impact on the color change of the hybrid ceramics. Lava samples showed more significant color changes compared to Enamic samples across all groups and periods, except for the samples stored in coffee-wine.
