摘要:

目的 评价10种光固化复合树脂在不同溶液中的颜色稳定性及吸水溶解性能。 方法 10种光固化复合树脂分别为:BeautifilⅡ(B2)、Ceram. X One Universal(CXU)、Charisma(CS)、Charisma Diamond(CD)、Denfil(DF)、DX. Universal(DXU)、Filtek Z250(Z250)、Filtek Z350 XT(Z350)、FS-1(FS)、Magnafill Putty(MP)。每种树脂材料各制作20个试件,随机分为4组(n=5),分别浸入蒸馏水(对照组)、咖喱、咖啡和红酒28 d,分光光度计测量试件浸入前及浸入后1、7、14、21和28 d的色度值(CIE L∗a∗b∗),计算染色前后色差值。根据ISO 4049: 2019标准,每种材料制作3个试件,测量材料的吸水性和溶解性。采用三因素方差分析评估树脂材料、染液、染色时间对染色前后色差值(ΔE)的影响,采用单因素方差分析比较不同材料的吸水值和溶解值变化。 结果 随着染色时间增加,所有试件均出现一定程度的颜色变化。树脂材料类型、染液类型、染色时间以及三者的交互作用对ΔE的影响均具有统计学意义(P<0.001)。所测材料任一时间点颜色变化:咖喱>红酒>咖啡>蒸馏水。浸入咖喱、咖啡、红酒7 d后所有材料均出现临床不可接受的变色(ΔE>3.3)。浸入咖喱28 d后,CS的ΔE最小,DXU的ΔE最大;浸入咖啡28 d后,FS的ΔE最小,DXU的ΔE最大;浸入红酒28 d后,FS的ΔE最小,Z350的ΔE最大。MP与CXU在所有溶液中的色差值均较小。Z350吸水值最高,MP吸水值最低;CS和CD的溶解值高于其他材料。 结论 光固化复合树脂的颜色稳定性具有材料依赖性,并受色素种类、浸泡时间的影响;MP与CXU的颜色稳定性较好;MP的吸水性和溶解性较低。

Abstract:

Objective This study aims to evaluate the color stability and related properties including water sorption and solubility of ten light-cured composite resins in different solutions. Methods A total of 10 composite resins were BeautifilⅡ(B2) and Ceram. X One Universal (CXU), Charisma (CS), Charisma Diamond (CD), Denfil (DF), DX. Universal (DXU), Filtek Z250 (Z250), Filtek Z350 XT (Z350), FS-1 (FS), and Magnafill Putty (MP). Meanwhile, a total of 20 disk-shaped samples were fabricated and randomly divided into four groups (n=5), which were immersed in distilled water (control group), curry, coffee, and red wine for 28 days. The color (CIE L∗a∗b∗) was measured by a spectrophotometer at baseline and 1, 7, 14, 21, and 28 days after immersion, and the color differences were calculated. Water sorption and solubility values were measured ba-sed on ISO 4049: 2019. In addition, three-way ANOVA was used to evaluate the influence of resin materials, solutions, and immersion time on discoloration results, meanwhile, one-way ANOVA was used to compare the water sorption values and solubility values of different materials. Results All samples showed a certain degree of color change with time. Color differences were significantly influenced by materials, solutions, and immersion time (P<0.001). The color changes of the measured materials at any time point: curry>red wine>coffee>distilled water. Thus, all materials showed clinically unacceptable discoloration (ΔE>3.3) after immersing in staining curry, coffee, and red wine for 7 days. Therefore, when immersed in curry for 28 days, CS and DXU had the smallest and the largest color difference. In addition, when immersed in coffee for 28 days, FS showed the smallest color change and DXU showed the largest. Moreover, when immersed in red wine for 28 days, FS showed the smallest color change and Z350 showed the largest. Furthermore, MP and CXU had small color differences in all solutions. Meanwhile, Z350 had the highest water sorption and MP had the lowest. The solubility values of CS and CD were significantly higher than those of other materials. Conclusion The color stability of light-cured composite resin is materials-depended and affected by pigment types and immersion time. Thus, MP and CXU have better color stability. MP has low water sorption.
