This study aimed to investigate the effect of common mouthwashes on the color change of a nanohybrid composite and its further stain susceptibility to Coke and coffee. One hundred and fifty composite discs were prepared and initial color values were measured using a spectrophotometer. The specimens were grouped based on the 24h exposure to common mouthwashes including Listerine, chlorhexidine, two types of fluoride mouthwashes (alcohol free and alcohol containing) as well as distilled water as control (N=30). The color change (ΔE1) values were calculated to show the amount of color change caused by mouthwashes. Subsequently, the specimens in each group were subdivided and immersed in the secondary colorant solution (coffee, Coke and, distilled water) for seven days. The total color change (ΔE total) values were obtained to show the stain susceptibility. Statistical analysis was conducted using ANOVA and Tukey's post hoc test. A P-value less than 0.05 was considered statistically significant. The calculated ΔE1 of resin composite was significantly higher for all mouthwash groups than that of the control group; however, all were in the clinically acceptable range. Exposure to Listerine and distilled water caused more staining effects compared to other mouthwashes after immersion in secondary colorant solutions. Regardless of primary mouthwash type, coffee and distilled water caused the highest and the least total discolorations, respectively (P<0.001). All mouthwashes caused a clinically acceptable color change in resin composite; however, further stain susceptibility depended on the mouthwashes but was not higher than distilled water.
本研究旨在调查常用漱口水对纳米混合复合材料颜色变化的影响及其对可乐和咖啡的进一步染色敏感性。制备了150个复合树脂圆盘，并使用分光光度计测量初始颜色值。根据对包括李施德林、氯己定、两种含氟漱口水（不含酒精和含酒精）以及作为对照的蒸馏水在内的常用漱口水24小时的暴露情况将标本分组（N = 30）。计算颜色变化（ΔE1）值以显示漱口水引起的颜色变化量。随后，将每组中的标本再细分并浸入二次着色剂溶液（咖啡、可乐和蒸馏水）中7天。获得总颜色变化（ΔE总）值以显示染色敏感性。使用方差分析和Tukey事后检验进行统计分析。P值小于0.05被认为具有统计学意义。树脂复合材料计算出的ΔE1在所有漱口水组中均显著高于对照组；然而，所有均在临床可接受范围内。与其他漱口水相比，在浸入二次着色剂溶液后，使用李施德林和蒸馏水导致的染色效果更明显。无论初次使用的漱口水类型如何，咖啡和蒸馏水分别导致最高和最低的总变色（P < 0.001）。所有漱口水在树脂复合材料中均引起临床可接受的颜色变化；然而，进一步的染色敏感性取决于漱口水，但不高于蒸馏水。
