Abstract

Objectives: Modern dentistry has introduced color-matching restorations along with commercial finishing/polishing kits to improve color stability. This study aims to evaluate the effect of three finishing and polishing kits on the color stability of Filtek™ Z250 resin composite.

Methods: This study involved 140 resin composite discs categorized into three experimental groups: Sof-Lex, Super-Snap, and OptiDisc (40 discs each), along with a control group of 20 discs. Each disc was exposed to either coffee or cola after finishing or following both finishing and polishing. Mean color change was computed for each group. A One-Way ANOVA was conducted to compare mean color changes among the finishing kits.

Results: Super-Snap demonstrated the highest color stability among different finishing kits for Filtek™ Z250 resin composites in coffee staining, with a mean color change of 10.7. After finishing and polishing, its color stability improved to 10.2. For cola staining, Super-Snap had a mean color stability of 2.98, which decreased to 2.07 after polishing. However, there were no significant differences between the kits (p > 0.05). Furthermore, immersion in coffee resulted in significantly greater color changes compared to cola for all tested groups (p < 0.05).

Conclusion: The three multi-step finishing and polishing kits for Filtek™ Z250 demonstrated similar color stability, with coffee showing a higher staining potential than cola. Patients with anterior composite restorations may require education about the risk of staining and the importance of dental follow-ups to maintain the aesthetic quality of their restorations.

使用不同抛光套件评估树脂复合材料样品的颜色稳定性：体外研究。

目的：现代牙科已经引入了颜色匹配修复以及商业精加工/抛光套件，以提高颜色稳定性。本研究旨在评估三种精加工和抛光套件对Filtek™Z250树脂复合材料颜色稳定性的影响。方法：140个树脂复合椎间盘分为sofo - lex、Super-Snap和OptiDisc三组（每组40个），对照组20个。在完成或完成和抛光后，每个光盘都暴露在咖啡或可乐中。计算各组的平均颜色变化。采用单因素方差分析比较整理套件的平均颜色变化。结果：Super-Snap在不同的整理套件中对Filtek™Z250树脂复合材料在咖啡染色中表现出最高的颜色稳定性，平均颜色变化为10.7。经整理抛光后，其颜色稳定性提高到10.2。对于可乐染色，Super-Snap的平均颜色稳定性为2.98，抛光后下降到2.07。两组间差异无统计学意义（p < 0.05）。此外，与可乐相比，浸泡在咖啡中会导致所有测试组的颜色变化明显更大(p结论：Filtek™Z250的三个多步骤整理和抛光套件显示出相似的颜色稳定性，咖啡比可乐显示出更高的染色潜力。使用前牙复合修复体的患者可能需要接受有关染色风险的教育，以及牙科随访以保持修复体美学质量的重要性。
