Abstract

Purpose: To evaluate the effect of whitening mouthwashes with different active ingredients on the color change (ΔE₀₀) of a stained resin composite.

Methods: A total of 70 resin composite samples (G-aenial Anterior) with dimensions of 8 х 2 mm were prepared. The samples were immersed in coffee for 14 days to simulate time-dependent color change, then randomly assigned into seven groups (n=10). Listerine Advanced White (LAW), Splat White Plus (SWP), Colgate Optic White (COW), Colgate Plax White + Charcoal (CPC), Global White Charcoal Extra Whitening Mouthwash (GWE), R.O.C.S Black Edition Whitening Mouthwash (ROC), and distilled water (DW) were used over a 12-month period. Color measurements were performed at baseline, after staining, and after 1 month, 3 months, 6 months, and 12 months of use.

Results: Resin composite exhibited discoloration exceeding the 50:50% acceptability threshold (AT) (ΔE₀₀: 1.8) after 14 days of coffee immersion. Group, immersion period, and their interaction significantly affected the ΔE₀₀ values (P< 0.001). All whitening mouthwashes except SWP reduced the color change on resin composite below the AT, while COW achieved this level after 1 month of use, LAW and CPC after 3 months of use, and GWE and ROC after 12 months of use. The effectiveness of whitening mouthwashes in improving the color of stained resin composite varies depending on the formulation of the whitening mouthwash and immersion time. All whitening mouthwashes except SWP were effective in improving the color of resin composite.

Clinical significance: The color improvement effect of whitening mouthwashes on resin composite may be affected by the specific formulation and duration of use of whitening mouthwash.

美白漱口水对树脂复合材料颜色变化的影响。
目的:评价含不同活性成分的美白漱口水对染色树脂复合材料颜色变化的影响(ΔE₀0)。方法:制备尺寸为8 ~ 2mm的树脂复合材料(G-aenial Anterior) 70个。将样品浸泡在咖啡中14天,以模拟随时间变化的颜色变化,然后随机分为7组(n=10)。在12个月的时间里,研究人员使用了李斯德林Advanced White (LAW)、Splat White Plus (SWP)、高露洁optical White (COW)、高露洁Plax White + Charcoal (CPC)、Global White Charcoal Extra美白漱口水(GWE)、R.O.C.S Black Edition美白漱口水(ROC)和蒸馏水(DW)。在基线、染色后、使用1个月、3个月、6个月和12个月后进行颜色测量。结果:树脂复合材料在咖啡浸泡14天后变色超过50:50可接受阈值(AT) (ΔE 0 0: 1.8)。实验组、浸泡时间及其交互作用显著影响ΔE 00值(P< 0.001)。除SWP外,所有美白漱口水均将树脂复合材料的颜色变化降低到AT以下,而COW在使用1个月后达到此水平,LAW和CPC在使用3个月后达到此水平,GWE和ROC在使用12个月后达到此水平。美白漱口水改善染色树脂复合材料颜色的效果取决于美白漱口水的配方和浸泡时间。除SWP外,所有美白漱口水均能有效改善树脂复合材料的颜色。临床意义:美白漱口水对树脂复合材料的显色效果可能受美白漱口水的具体配方和使用时间的影响。
