Effect of different beverages on the color stability and microhardness of CAD/CAM hybrid versus feldspathic ceramic blocks: An in-vitro study

Changes in the physical properties and color stability of aesthetic restorative materials caused by various beverages

“…Badra et al revealed that the microhardness of materials immersed in coffee and Coca-Cola remained stable up to 7 days, but showed a decrease after 30 days 14) . However, Saba et al showed that immersion in beverages resulted in decreased microhardness and color change in CAD/CAM hybrid compared to feldspathic ceramic blocks 23) . Tanthanuch et al also showed a decrease in microhardness in restorative materials after being immersed in beverages 17) , and the results presented herein agree with those previously reported.…”

The Effect of Thermocycling on the Translucency and Color Stability of Modified Glass Ceramic and Multilayer Zirconia Materials

“…Color stability was assessed by calculating Delta E (ΔE) using L*a*b* values against the black background only [14]. T1 black readings were used as the baseline parameter against which Delta E comparisons were made.…”

“…T1 black readings were used as the baseline parameter against which Delta E comparisons were made. The values of ΔE ≥3.3 were considered clinically unacceptable [14].…”

In Vitro Effect of Alcohol and Non-Alcohol Based Mouth Rinses on Color Stability of CAD/CAM Resin Ceramic and Feldspathic Ceramics

“…Although color changes were in the range of clinical acceptability, the color change values after immersion in distilled water for Vita Enamic (1.52 ± 0.2) and Vitablocs Mark II (1.07 ± 0.1) were significantly different that could be related to the resin part confined in Vita Enamic (27) .…”

“…Patient awareness and needs has been increased not only for an aesthetic material but also color stable ones (27) . Hybrid ceramics were developed to overcome the problematic properties associated with resin and ceramic block materials when solely used.…”
