The aim of this in vitro study was to investigate the effect of different solutions on color stability of CAD/CAM provisional materials. One hundred and twenty rectangular specimens of 2 mm thickness for each provisional material were fabricated. Four subgroups (n = 10) were obtained from each group. The specimens were stored in artificial saliva, tea, coffee and cherry juice at 37 °C for 28 days. Spectrophotometry was used for measuring the color differences (CIEDE2000 [DE00]) before and after each storage. Statistical analysis was performed using 2-way analysis of variance (ANOVA), and Tukey's HSD test was used for the comparison of mean values (α = 0.05). There were statistically significant differences between materials and solutions (P <.001). There was a significant difference between all groups, among the solutions (P <.001). The lowest change was observed in saliva. When ΔE00 values were compared, there was no difference between Teliocad and Vitacad (P =.751). Overall, Temdent immersed in coffee showed the highest color change (2.74 ± 0.15) and the lowest values were calculated in Vitacad stored in saliva (0.36 ± 0.02). CLINICAL IMPLICATIONS: CAD/CAM interim restoration materials can be used safely in the oral environment in terms of color stability.
本体外研究的目的是调查不同溶液对CAD/CAM临时材料颜色稳定性的影响。每种临时材料制作了120个厚度为2毫米的矩形试件。每组试件分为四个亚组（n = 10）。将试件在37℃下分别储存在人工唾液、茶、咖啡和樱桃汁中28天。使用分光光度法测量每次储存前后的颜色差异（CIEDE2000[ΔE00]）。采用双向方差分析（ANOVA）进行统计分析，并用Tukey's HSD检验比较平均值（α = 0.05）。材料和溶液之间存在统计学显著差异（P <.001）。溶液之间所有组间均存在显著差异（P <.0）。唾液中的颜色变化最小。比较ΔE00值时，Teliocad和Vitacad之间无差异（P = 0.751）。总体而言，浸泡在咖啡中的Temdent颜色变化最大（2.74±0.15），储存在唾液中的Vitacad颜色变化最小（0.36±0.02）。临床意义：就颜色稳定性而言，CAD/CAM临时修复材料可在口腔环境中安全使用
