Evaluation of the Effect of Saudi Coffee Consumption in Comparison to Various Types of Coffees on the Color of Novel Aesthetic Dental Ceramics.
The aim of this study was to evaluate the effect of Saudi coffee consumption in comparison to various types of commonly used coffees (instant black, Turkish, and espresso) on the color of novel aesthetic dental ceramics. A total of 144 flat cylindrical discs with an 8-mm diameter and 0.5-mm thickness were created using CAD/CAM technology. Three ceramic materials were used: Lithium disilicate (Emax) and two ultra-translucent monolithic zirconia ceramics; Aidite and Cercon Xt (Cer). The specimens were immersed in six coffee solutions: Saudi coffee from eastern region (ES), Saudi coffee from northern region (SN), Saudi coffee from middle region (SM), instant black coffee (Ne), Turkish coffee (Tk) and espresso coffee (Es). All specimens (n = 8) were immersed for a period of 15 days. The color of all specimens was measured before and after immersion, and the CIE L*a* b* coordinates were obtained with a spectrophotometer. Values for the translucency parameter (TP), contrast ratio (CR) and color change (ΔE) for each specimen were calculated. Data were analyzed using paired sample t-test and one-way ANOVA and post hoc testing. Color coordinates L*, a* and b* significantly changed after immersion in all coffee solutions relative to pre-immersion values, with a noticeable decrease in lightness (L*) (P < .05). A significant color change (∆E) was observed in all tested materials in all coffee solutions after immersion, with ∆E values exceeding 5.26 (P < 0.05). Color changes (∆E) for specimens immersed in the three formulations of Saudi coffee were significantly less than those immersed in the other coffee solutions (P < 0.05). Saudi coffee with formulations from the northern region resulted in more color changes in Emax in comparisons to the other two Saudi coffee formulations from the middle and eastern regions. Aidite and Cer ceramics showed less TP values than Emax. Consumption of coffee for a period of simulated 1 year has significantly altered the color of ceramic materials to a level above the threshold at which the clinical perception of color change occurred (> 3.3). Saudi coffee consumption caused less changes in the color of tested ceramics in comparison to the consumption of commonly used coffees (instant black, turkish, and espresso).
