Abstract

PURPOSE

To evaluate the color stability of esthetic restorative materials after immersion in mouthwashes and accelerated aging.

MATERIALS AND METHODS

Compomers and resin-based composites (RBC) were measured at baseline and repeatedly after immersion in three kinds of mouthwash (Listerine, Peridex, Rembrandt Age Defying) for 24 hrs and 7 days, and after aging for 150 kJ/m2. Color was measured according to CIE Lab* color scale on a reflection spectrophotometer.

RESULTS

After immersion for 7 days, the mouthwash groups did not produce significantly higher color changes than the distilled water group, except with some mouthwashes used with Tetric-Ceram. After immersion for 7 days and aging for 150 kJ/m2, the mouthwash groups did not produce significantly higher color changes than the distilled water group. Aging in weathering chamber produced color change (deltaE*) of 1.1-3.9, which was mainly influenced by the material. With some exceptions, the color changes from immersion of the RBCs and compomers in mouthwashes were not perceptible (deltaE*<3.3).

摘要

目的

评估美观修复材料在浸泡于漱口水及加速老化后的颜色稳定性。

材料与方法

对复合体和树脂基复合材料（RBC）在基线时进行测量，并在浸泡于三种漱口水（李施德林、派丽奥、伦勃朗抗老化漱口水）24小时和7天后，以及在经150 kJ/m²老化后反复测量。使用反射分光光度计根据CIE Lab*色标测量颜色。

结果

浸泡7天后，除了使用某些漱口水与Tetric-Ceram配合时，漱口水组产生的颜色变化并不比蒸馏水组显著更高。浸泡7天并经150 kJ/m²老化后，漱口水组产生的颜色变化也不比蒸馏水组显著更高。在老化试验箱中老化产生的颜色变化（ΔE*）为1.1 - 3.9，这主要受材料影响。除了一些例外情况，RBC和复合体浸泡在漱口中产生的颜色变化难以察觉（ΔE*<3.3）。
