The authors tested the hypothesis that surface-finishing treatments and the type of storage solutions significantly affected the staining of resin-based composites, or RBCs, and unfilled resins, or URs.
Fifty-four RBC and 54 UR disks were polymerized through a polyester film strip (Mylar, DuPont, Wilmington, Del.) and polished in one of three groups: 1-micrometer aluminum oxide, 15-microm diamond plate and no treatment (polyester film). All specimens were immersed in water for two days and then in coffee, cola or red wine for seven more days at 37 C. The authors recorded tristimulus color measurements before the immersions; after one and two days in water; and after one, two, three and seven days in the storage solutions.
Most of the color changes occurred between day 2 in water and day 7 in the staining solution. Analysis of variance showed that the finishing treatment and storage solution significantly influenced the overall color change (deltaE), and interactions occurred between the finishing treatment and the storage solution (P < .0001) for both materials. RBC specimens generally exhibited greater color changes than did UR specimens. The polyester film finishing exhibited the greatest amount of color change, while the diamond finishing exhibited the least amount of color change. Immersion in wine caused the greatest color change for both materials; cola and coffee resulted in the smallest color change for RBC and UR specimens, respectively.
Finishing treatments and storage solutions significantly affect the surface staining of RBC materials. Polyester film finishing and red wine produced the greatest color change after seven days for RBC specimens.
Clinicians should remove the polyester film-finished surface and advise patients that drinking wine could intensify surface staining on RBC restorations.
作者检验了如下假设，即表面处理工艺和储存溶液类型对树脂基复合材料（RBC）及未填充树脂（UR）的染色有显著影响。
54个RBC圆盘和54个UR圆盘通过聚酯薄膜条（聚酯薄膜，杜邦公司，特拉华州威尔明顿市）聚合，并在以下三组之一中进行抛光处理：1微米氧化铝、15微米金刚石板以及未处理（聚酯薄膜）。所有标本先在水中浸泡两天，然后在37℃下于咖啡、可乐或红酒中再浸泡七天。作者记录了浸泡前、在水中浸泡一天和两天后以及在储存溶液中浸泡一天、两天、三天和七天后的三刺激值颜色测量结果。
大部分颜色变化发生在水中浸泡两天至染色溶液中浸泡七天之间。方差分析表明，表面处理工艺和储存溶液对总体颜色变化（ΔE）有显著影响，且两种材料在表面处理工艺和储存溶液之间均存在交互作用（P <.0001）。RBC标本通常比UR标本表现出更大的颜色变化。聚酯薄膜表面处理的颜色变化最大，而金刚石表面处理的颜色变化最小。两种材料浸泡在红酒中时颜色变化最大；可乐和咖啡分别导致RBC和UR标本颜色变化最小。
表面处理工艺和储存溶液对RBC材料的表面染色有显著影响。对于RBC标本，聚酯薄膜表面处理和红酒在七天后产生的颜色变化最大。
临床医生应去除聚酯薄膜处理过的表面，并告知患者饮用红酒会加剧RBC修复体的表面染色。
