Abstract

This in vitro study aimed to compare the effect of external staining agents (black tea and grape juice) on the color change of three hybrid ceramics including a new material in comparison to zirconia-reinforced lithium silicate. Ten samples of two hybrid dental ceramics including Vita Enamic (Vita Zahnfabrik) and Crystal Ultra (Digital Dental) in addition to a resin nanoceramic, Lava Ultimate (3M ESPE); and a zirconia-reinforced lithium silicate glass ceramic, Vita Suprinity (Vita Zahnfabrik) were prepared and immersed in black tea or grape juice for 30 days. A spectrophotometer was used to evaluate color change. All samples were carefully chosen in A3 shades or their equivalent. Two-way ANOVA and Bonferroni tests were used to analyze the color differences (ΔE00) among the materials and the staining solutions at a significant level of 0.05. Significant color changes were observed in Vita Enamic and Lava Ultimate groups after immersion in both solutions (P<0.001). The least color changes (ΔE00) belonged to the Vita Suprinity (1.34) and Crystal Ultra (1.92) groups, respectively. The color changes of Vita Enamic and Lava Ultimate materials were beyond clinical acceptability. However, the mean color changes of Vita Suprinity and Crystal Ultra groups were clinically acceptable.

摘要

这项体外研究旨在比较外部染色剂(红茶和葡萄汁)对三种混合陶瓷颜色变化的影响,其中包括一种新材料,并与氧化锆增强硅酸锂进行比较。制备了两种混合牙科陶瓷的十个样本,包括维他依纳米(维他齿科工厂)和晶钻超瓷(数字牙科),此外还有树脂纳米陶瓷拉瓦优耐(3M 艾世必);以及一种氧化锆增强硅酸锂玻璃陶瓷维他素普瑞尼(维他齿科工厂),并将它们浸泡在红茶或葡萄汁中30天。使用分光光度计评估颜色变化。所有样本均精心选择为A3色阶或其等效色阶。采用双向方差分析和邦费罗尼检验,以0.05的显著水平分析材料和染色溶液之间的颜色差异(ΔE00)。浸泡在两种溶液中后,维他依纳米和拉瓦优耐组均观察到显著的颜色变化(P<0.001)。颜色变化最小(ΔE00)的分别是维他素普瑞尼组(1.34)和晶钻超瓷组(1.92)。维他依纳米和拉瓦优耐材料的颜色变化超出了临床可接受范围。然而,维他素普瑞尼和晶钻超瓷组的平均颜色变化在临床上是可接受的。
