The aim of the study was to evaluate the effect of commonly used mouthrinses on the discoloration and whiteness of resin-based restoratives (RBR). Two hundred disc shaped specimens (5mm diameter, 2mm tick) of a micro-hybrid composite (FZ-Filtek Z250, 3M ESPE), a ormocer (AD-Admira, Voco), a giomer (BE-Beautifil II, Shofu) and a compomer (DX-Dyract XP, Dentsply) RBRs were prepared (50 from each). The specimens were stored in distilled water for 24 h, then immersed for another 12 h in five mouthrinses of distilled water, Klorhex, Tantum Verde, Oral-B Complete Lasting Freshness and Listerine Cool Mint. The specimens were subjected to color measurements, using a spectrophotometer (VITA Easyshade V, VITA Zahnfabrik) before and after immersion. Color change (ΔE00) and whiteness index (WID) were calculated and data were analyzed using one-way ANOVA, two-way ANOVA and post-hoc Tukey’s test (p < 0.05). BE was the most colored RBRs in all solutions. ΔE₀₀ values of all RBRs immersed in Tantum Verde were above the acceptability threshold. DX showed the highest negative ΔWID values in all solutions. ΔE₀₀ and ΔWID showed higher values for all RBRs when immersed in Tantum Verde. FZ and AD are the most successful, BE and DX are the most unsuccessful RBRs in terms of on color stability and whiteness caused by the use of mouthrinse. After all RBRs were immersed in different mouthrinses, they changed in terms of color and whiteness.

各种漱口水对树脂基修复材料颜色稳定性和白度的影响

该研究的目的是评估常用漱口水对树脂基修复剂 (RBR) 变色和白度的影响。200 个微混合复合材料（FZ-Filtek Z250、3M ESPE）、ormocer（AD-Admira、Voco）、giomer（BE-Beautifil II、Shofu）和制备复合体（DX-Dyract XP，Dentsply）RBR（各50个）。将样品在蒸馏水中储存 24 小时，然后再浸入 5 种蒸馏水、Klorhex、Tantum Verde、Oral-B Complete Lasting Freshness 和 Listerine Cool Mint 漱口水中 12 小时。在浸泡前后，使用分光光度计（VITA Easyshade V，VITA Zahnfabrik）对样品进行颜色测量。计算颜色变化 (ΔE00) 和白度指数 (WID) 并使用单向方差分析分析数据，p  < 0.05)。BE 是所有溶液中颜色最多的 RBR。浸入 Tantum Verde 中的所有 RBR 的Δ E ₀₀值均高于可接受阈值。DX 在所有溶液中显示出最高的负 ΔWID 值。当浸入 Tantum Verde 时，所有 RBR 的Δ E ₀₀和 ΔWID 显示出更高的值。FZ 和 AD 是最成功的，BE 和 DX 是最不成功的 RBR，在使用漱口水引起的颜色稳定性和白度方面。在所有 RBR 浸入不同的漱口水后，它们的颜色和白度都会发生变化。
