This study investigated whether commercially available mouthwashes could affect or change the color of a hybrid composite resin. Twenty-four disks were fabricated and divided into eight equal groups for testing. At baseline, six colorimetric recordings and color parameters (L*, a*, b*) were recorded for each grouping of disks using a Chroma Meter CR-300 in reflectance mode. The groups of disks were immersed in their respective mouthwashes for 2 minutes a day in a vibratory fashion over a 6-month period. At the end of 6 months, color differences, delta E, were calculated between the base line and test recordings. The results indicate that rinsing with mouthwashes for 6 months can cause a hybrid resin to undergo color variations. Except for one product the color variations were not clinically significant.
本研究调查了市售漱口水是否会影响或改变混合复合树脂的颜色。制作了24个圆盘并将其分成8个相等的组进行测试。在基线时，使用色度计CR - 300在反射模式下为每组圆盘记录6次比色记录和颜色参数（L*、a*、b*）。圆盘组在6个月的时间里以振动方式每天在各自的漱口水 中浸泡2分钟。在6个月末，计算基线和测试记录之间的颜色差异ΔE。结果表明，用漱口水冲洗6个月会导致混合树脂发生颜色变化。除一种产品外，颜色变化在临床上并不显著。
