| Abstract | ||||
| Statement of problem: color stability of ceramic restorations upon common beverage consumption assures its esthetics and clinical acceptability. This study was formulated to evaluate the effect of coffee consumption on color stability of different CAD/CAM ceramics used for esthetic restoration fabrication. Materials and methods: A total of 45 discs were constructed of (IPS Emax CAD, Vita Suprinity & Vita Enamic) 10 mm in diameter and 1.5 mm thick. Samples were divided into three groups (15 discs each) according to the tested material then immersed in instant coffee solution for 12 days, at 37° C in dark environment. Ceramic discs of each material were optically connected with drop of distilled water to composite substrate background. The CIE L* a *b color parameters were recorded before immersion, and after immersion in coffee solution using a spectrophotometer. Data were recorded, tabulated, and statistically analyzed Results: A statistical insignificant difference in mean values of (ΔE) was detected between tested ceramics immersed in coffee. Conclusions: The color of the three tested ceramics changed on immersion in coffee; (ΔE) values were above 3.3, which is clinically unacceptable and unaesthetic. Recommendations: Dentists should warn patients about the effects of dietary habits and staining beverages on dental ceramics. | ||||
