This study aimed to evaluate the in vitro effects of coffee exposure on the color and roughness of conventional and bulk-fill resin composites, with and without surface pre-reacted glass-ionomer (S-PRG) filler.
Forty-eight cylindrical samples (Ø6 mm × 2 mm) were prepared and categorized as follows (n = 12 per group): conventional nano-hybrid (Tetric N-Ceram, Ivoclar); nano-hybrid with S-PRG filler (Beautifil II, Shofu); bulk-fill (Tetric N-Ceram Bulk Fill, Ivoclar); and bulk-fill with S-PRG filler (Beautifil Bulk Restorative, Shofu). The samples were assessed for surface roughness (Ra, μm), color coordinates (CIE Lb), and overall color change (ΔE, ΔE). Measurements were taken at baseline and after 7 days of coffee immersion (pH = 4.95). Data were analyzed using generalized linear models, Kruskal-Wallis, Dunn, and paired Wilcoxon tests (α = 0.05).
After the coffee exposure, all resin composites exhibited a significant decrease in L* (towards black), an increase in a* (towards red), an increase in b* (towards yellow), and a higher Vita color score (p < 0.05). Tetric N-Ceram demonstrated the lowest roughness values post-exposure; however, a significant increase in roughness over time was observed only for Tetric N-Ceram Bulk Fill (p < 0.05). For ΔE, Beautifil Bulk Restorative and Tetric N-Ceram showed higher values compared to Beautifil II. For ΔE, a significant difference was noted between Beautifil Bulk Restorative and Beautifil II (p < 0.05).
Resin composites with S-PRG fillers exhibited similar pigmentation dynamics to conventional composite but showed greater surface roughness after exposure to coffee. Considering the S-PRG materials, the bulk-fill version is more susceptible to staining.
本研究旨在评估咖啡暴露对含和不含表面预反应玻璃离子(S-PRG)填料的传统树脂复合材料和大块充填树脂复合材料颜色及粗糙度的体外影响。
制备48个圆柱形样本(直径6mm×2mm),并分类如下(每组n = 12):传统纳米混合树脂(Tetric N-Ceram,义获嘉);含S-PRG填料的纳米混合树脂(Beautifil II,松风);大块充填树脂(Tetric N-Ceram Bulk Fill,义获嘉);以及含S-PRG填料 的大块充填树脂(Beautifil Bulk Restorative,松风)。对样本进行表面粗糙度(Ra,μm)、颜色坐标(CIE Lb)和总颜色变化(ΔE,ΔE)评估。在基线时以及咖啡浸泡7天(pH = 4.95)后进行测量。使用广义线性模型、Kruskal-Wallis检验、Dunn检验和配对Wilcoxon检验(α = 0.05)对数据进行分析。
咖啡暴露后,所有树脂复合材料的L值均显著降低(趋向黑色),a值增加(趋向红色),b*值增加(趋向黄色),且Vita颜色评分更高(p < 0.05)。暴露后,Tetric N-Ceram的粗糙度值最低;然而,仅Tetric N-Ceram Bulk Fill的粗糙度随时间显著增加(p < 0.05)。对于ΔE,Beautifil Bulk Restorative和Tetric N-Ceram的值高于Beautifil II。对于ΔE,Beautifil Bulk Restorative和Beautifil II之间存在显著差异(p < 0.05)。
含S-PRG填料的树脂复合材料与传统复合材料表现出相似的色素沉着动态,但在接触咖啡后表面粗糙度更大。考虑到S-PRG材料,大块充填型更容易染色。
