摘要

目的:研究咖啡暴露对常规树脂复合材料和填充型树脂复合材料(含和不含表面预反应玻璃离子聚合物(S-PRG))的颜色和粗糙度的体外影响。方法:制备48个圆柱形样品(Ø6 mm × 2mm),并按每组12个进行分类:常规纳米杂化(Tetric n - ceram, Ivoclar);S-PRG纳米杂化填料(Beautifil II, Shofu);散装填充物(n -陶瓷散装填充物);用S-PRG填充剂(Beautifil Bulk Restorative, Shofu)进行填充。评估样品的表面粗糙度(Ra, μm),颜色坐标(CIE Lab)和整体颜色变化(ΔEab, ΔE00)。在基线和咖啡浸泡7天后(pH = 4.95)进行测量。数据分析采用广义线性模型、Kruskal-Wallis、Dunn和配对Wilcoxon检验(α = 0.05)。结果:咖啡暴露后,所有树脂复合材料的L*(向黑色)显著降低,a*(向红色)显著增加,b*(向黄色)显著增加,Vita颜色评分较高(p < 0.05)。曝光后,n -陶瓷的粗糙度值最低;然而,随着时间的推移,只观察到n -陶瓷填充材料的粗糙度显著增加(p < 0.05)。对于ΔEab,与Beautifil II相比,Beautifil Bulk Restorative和tric N-Ceram的数值更高。对于ΔE00, Beautifil Bulk Restorative和Beautifil II之间存在显著差异(p < 0.05)。结论:含S-PRG填料的树脂复合材料具有与常规复合材料相似的色素沉着动力学,但暴露于咖啡后表面粗糙度更大。考虑到S-PRG材料,散装填充版本更容易染色。

Surface Roughness and Color Stability of Conventional and Bulk-Fill Resin Composite with S-PRG Fillers After Coffee Exposure: An in-vitro Study.

Objective: 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.

Methodology: 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 Lab), and overall color change (ΔEab, ΔE00). 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).

Results: 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 ΔEab, Beautifil Bulk Restorative and Tetric N-Ceram showed higher values compared to Beautifil II. For ΔE00, a significant difference was noted between Beautifil Bulk Restorative and Beautifil II (p < 0.05).

Conclusion: 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.
