摘要

目的:空气粉末抛光(APP)会导致复合材料表面粗糙,因此随着时间的推移而发生的颜色变化会对美学产生负面影响。为了避免再抛光对树脂复合材料表面粗糙度和变色的负面影响,我们首次研究了再抛光对树脂复合材料表面粗糙度和变色的影响。方法:将39个复合椎间盘随机分为3组:I组:对照组(n = 13), II组:空气粉抛光组(n = 13), III组:空气粉抛光+再抛光组(n = 13)。在咖啡中浸泡1周前后,测量圆盘的颜色和表面粗糙度。使用比色仪(CR-400,柯尼卡美能达)测量颜色,使用表面粗糙度分析仪(SJ-400, Mitutoyo, Japan)测量粗糙度。结果:除第三组外,各组样品的粗糙度均发生了显著变化,所有材料在咖啡中浸泡后相对于基线颜色均发生了显著变化。在粗糙度和颜色方面,两组之间没有统计学上的显著差异。结论:在本研究中,我们发现APP后的再抛光并没有显著改善复合修复体的颜色稳定性和粗糙度。altau N, Sağır K, Aydınoğlu A, Gözetici Çil B, Keleşoğlu E, Sağır K, Hazar Yoruç AB.再抛光对空气研磨树脂复合材料表面粗糙度和颜色稳定性的影响。国际医学杂志,2016;12(3):137-42。https://doi.org/10.5577/intdentres.2022.vol12.no3.5语言修改:本手稿中的英语已由至少两名专业编辑检查,他们都是英语母语者。

Effect of repolishing on the surface roughness and color stability of air-abraded resin composites
Aim: Air powder polishing (APP) can cause roughness on composite surfaces, and consequently the color change that occurs over time affects the aesthetic negatively. Here, we aim to investigate the effect of repolishing on the roughness and discoloration of resin composites after APP to avoid its negative effects for the first time. Methodology: A total of 39 composite discs were randomly allocated into three groups: Group I: Control (n = 13), Group II: Air Powder Polished (n = 13), and Group III: Air Powder Polished + Re-polished (n = 13). Color and surface roughness of the discs were measured before and after immersion in coffee for 1 week. Color was measured using a colorimeter (CR-400, Konica Minolta), and roughness was measured using a surface roughness analyzer (SJ-400, Mitutoyo, Japan). Results: All specimens in the groups, except those in Group III, showed significant changes in roughness, and all materials showed significant color changes after immersion in the coffee relative to the baseline. There was no statistically significant difference between the groups in terms of roughness and color. Conclusion: In this study, we showed that repolishing after APP does not significantly improve the color stability and roughness of the composite restorations.   How to cite this article: Altaş N, Sağır K, Aydınoğlu A, Gözetici Çil B, Keleşoğlu E, Sağır K, Hazar Yoruç AB.
