The aim of the present study was to evaluate three mouth rinse solutions' (Plax, Listerine and Periogard) influence on the microhardness and color stability of a composite resin (Esthet.X, Dentsply).
For this purpose, forty specimens were prepared, being 10 specimens for each solution and 10 for artificial saliva (control group). Initially, specimens were polished and immersed in artificial saliva and following the initial color, an evaluation was made. For 30 days, specimens were immersed in the solutions three times a day for 1 min. After this cycling period, color change was analyzed and Knoop microhardness measures were carried out. A new color measurement was performed after repolishing the specimens.
The microhardness and color stability results showed no statistically significant difference among the studied solutions. However, samples immersed in Periogard showed a significant alteration in the composite resin brightness test.
It can be concluded that mouth rinse can influence the luminosity of composite resin.
本研究旨在评估三种漱口水（必固齿、李施德林和派丽奥）对复合树脂（Esthet.X，登士柏）显微硬度和颜色稳定性的影响。
为此，制备了40个样本，每种溶液10个样本，人工唾液（对照组）10个样本。最初，将样本抛光并浸入人工唾液中，记录初始颜色后进行评估。在30天内，样本每天浸入溶液3次，每次1分钟。在此循环期后，分析颜色变化并进行努氏显微硬度测量。样本重新抛光后进行新的颜色测量。
显微硬度和颜色稳定性结果显示，在所研究的溶液之间没有统计学上显著的差异。然而，浸入派丽奥的样本在复合树脂亮度测试中显示出显著变化。
可以得出结论，漱口水会影响复合树脂的亮度。
