To analyze the color stability of Bulk-fill resins immersed in chicha morada and light-cured at different distances (0 mm, 2 mm and 4 mm).
This experimental study included a total of 216 Bulk-fill resin discs. The specimens were distributed into nine groups of 24 discs based on the type of resin (3M ESPE Filtek™ Bulk Fill, Ivoclar Tetric N-Ceram Bulk Fill and FGM Opus Bulk-fill APS), light-curing distances (0, 2 and 4 mm) and staining solution (control with distilled water and Naturalle chicha morada). Color measurements were taken 24 hours after fabrication and immersion in distilled water and Naturalle chicha morada at 24 hours, 1 week and 3 weeks.
Light-curing distances affected the color stability of the resins with 3M ESPE and Ivoclar, exhibiting significant color changes at all evaluated time points when immersed in chicha morada. For the Delta (ΔE) value 3M ESPE and Ivoclar resin discs immersed in chicha morada showed significant changes at 24 hours 1 week and 3 weeks (p = .001, p = .000 and p = .000; and p = .000 p = .000 and p = .000 respectively). However, FGM resin discs exhibited significant changes only at 24 hours and 1 week (p = .000 and p = .001). FGM showed better color stability compared to 3M ESPE and Ivoclar at 3 weeks of immersion in chicha morada. All three commercial brands showed a significant decrease in the "L" value as immersion time in chicha morada increased.
The study concluded that FGM demonstrated better chromatic stability over time compared to 3M ESPE and Ivoclar Ceram, which exhibited significant color changes influenced by immersion duration and photopolymerization distance.
分析大块充填树脂浸泡在紫玉米汁中并在不同距离（0毫米、2毫米和4毫米）光固化后的颜色稳定性。
本实验研究共纳入216个大块充填树脂圆盘。根据树脂类型（3M ESPE Filtek™ 大块充填树脂、义获嘉Tetric N-Ceram大块充填树脂和FGM Opus大块充填树脂APS）、光固化距离（0、2和4毫米）和染色溶液（用蒸馏水和Naturalle紫玉米汁作为对照）将样本分为9组，每组24个圆盘。在制作完成后24小时以及浸泡在蒸馏水和Naturalle紫玉米汁中24小时、1周和3周后进行颜色测量。
光固化距离影响了3M ESPE和义获嘉树脂的颜色稳定性，当浸泡在紫玉米汁中时，在所有评估时间点均表现出显著的颜色变化。对于Delta（ΔE）值，浸泡在紫玉米汁中的3M ESPE和义获嘉树脂圆盘在24小时、1周和3周时显示出显著变化（p = 0.001、p = 0.000和p = 0.000；以及p = 0.000、p = 0.000和p = 0.000）。然而，FGM树脂圆盘仅在24小时和1周时表现出显著变化（p = 0.000和p = 0.001）。在浸泡紫玉米汁3周时，FGM相比3M ESPE和义获嘉表现出更好的颜色稳定性。随着浸泡在紫玉米汁中的时间增加，所有三个商业品牌的“L”值均显著下降。
该研究得出结论，与3M ESPE和义获嘉Ceram相比，FGM随时间表现出更好的颜色稳定性，3M ESPE和义获嘉Ceram表现出受浸泡时间和光聚合距离影响的显著颜色变化。
