Abstract

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).

沙特咖啡消费量与不同类型咖啡对新型美学牙科陶瓷颜色的影响评价
本研究的目的是评估沙特咖啡消费量与各种常用咖啡(速溶黑咖啡、土耳其咖啡和浓缩咖啡)对新型美学牙科陶瓷颜色的影响。利用CAD/CAM技术,共制作了144个直径为8mm、厚度为0.5 mm的扁平圆柱形圆盘。使用了三种陶瓷材料:二硅酸锂(Emax)和两种超半透明单片氧化锆陶瓷;Aidite和Cercon Xt (Cer)。将样品浸泡在6种咖啡溶液中:东部地区的沙特咖啡(ES)、北部地区的沙特咖啡(SN)、中部地区的沙特咖啡(SM)、速溶黑咖啡(Ne)、土耳其咖啡(Tk)和浓缩咖啡(ES)。所有标本(n = 8)浸泡15天。在浸泡前后测量所有标本的颜色,并用分光光度计获得CIE L*a* b*坐标。计算每个标本的半透明参数(TP)、对比度(CR)和颜色变化(ΔE)的值。数据分析采用配对样本t检验、单因素方差分析和事后检验。在所有咖啡溶液中浸泡后,颜色坐标L*, a*和b*相对于浸泡前的值发生了显著变化,亮度(L*)明显降低(P 3.3)。与常用的咖啡(速溶黑咖啡、土耳其咖啡和浓缩咖啡)相比,沙特咖啡对测试陶瓷颜色的影响较小。
