One of the most important aspects that determines the clinical lifetime of aesthetic restorations, is the color stability (CS) over the long term. This study aims to assess the effect of artificial aging and thermocycling in different staining solutions on the CS of bioactive restorative materials compared to conventional ones.
The following four material groups were investigated: ACTIVA™ Bioactive (AB) (Pulpdent Corporation, Massachusetts, United States), Beautifil II (BF) (SHOFU Inc., Kyoto, Japan), Fuji II (FJ) (GC Corporation, Tokyo Japan), and Filtek™ Z350 XT (FT) (3M, Minnesota, United States). A total of 100 specimens were fabricated using an acrylic mold and then immersed in five staining solutions groups: coffee, black tea, Cola, mixed berry juice, and saline. Baseline shade (T0) was recorded using two spectro-photometer devices, VITA Easyshade® Advance (VITA Zahnfabrik, Baden-Wurttemberg, Germany) and Color-Eye® 7000A (X-Rite, Inc., Grand Rapids, Michigan, United States). Following this, the shade was recorded at 30 days (T1), three months (T2), and after 5000 thermocycles (5C-55C) (T3). CIE Lab* (International Commission on Illumination color space) data was used to calculate ΔE for each group.
All samples showed a significant color change (P<0.001) following one and three months of storage and after thermocycling. AB and BF showed the highest CS over time, whereas FT and FJ showed the least CS.
The CS of restorative materials is mostly determined by their type, followed by staining solution type and thermocycling. The most potent solutions were coffee, tea, and berry juice.
决定美学修复体临床使用寿命的最重要因素之一是长期的颜色稳定性（CS）。本研究旨在评估与传统生物活性修复材料相比，在不同染色溶液中进行人工老化和热循环对其颜色稳定性的影响。
研究了以下四个材料组：ACTIVA™生物活性材料（AB）（美国马萨诸塞州Pulpdent公司）、Beautifil II（BF）（日本京都SHOFU公司）、Fuji II（FJ）（日本东京GC公司）和Filtek™ Z350 XT（FT）（美国明尼苏达州3M公司）。使用丙烯酸模具制作了总共100个样本，然后将其浸入五个染色溶液组中：咖啡、红茶、可乐、混合浆果汁和盐水。使用两台分光光度计设备VITA Easyshade® Advance（德国巴登-符腾堡州VITA Zahnfabrik公司）和Color-Eye® 7000A（美国密歇根州大急流城X-Rite公司）记录基线色度（T0）。此后，在30天（T1）、三个月（T2）和5000次热循环（5℃-55℃）后（T3）记录色度。使用CIE Lab*（国际照明委员会颜色空间）数据计算每组的ΔE。
所有样本在储存1个月和3个月后以及热循环后均显示出显著的颜色变化（P<0.001）。随着时间的推移，AB和BF显示出最高的颜色稳定性，而FT和FJ显示出最低的颜色稳定性。
修复材料的颜色稳定性主要由其类型决定，其次是染色溶液类型和热循环。最具影响力的溶液是咖啡、茶和浆果汁。
