Abstract

Background: One of the aesthetic issues in the use of composite resin is the color change. The study aims to compare the color changes of nanofiller composite resin before and after immersion in red grape juice with different curing durations. Method: This study involved 18 round composite resins with a diameter of 12 mm and a thickness of 2 mm. The sample was divided into three groups (n=6); group A was cured for 20 seconds, group B for 30 seconds, and group C for 40 seconds. After curing, the samples were immersed in artificial saliva at 37°C for 24 hours before being measured by UV-vis spectrophotometer. The three groups were immersed in red grape juice for three days and the final color was measured. Data were analyzed using One Way Anova and Post Hoc LSD. Result: The One Way Anova test showed a significance value of 0.000, meaning (p < 0.05) it was said that there was a significant difference in each group followed by a post hoc LSD test on composite resin cured for 20 seconds against 30 seconds. second group and 40 seconds to get a significant difference Conclusion: Longer curing duration can defend nanofiller composite resin against discoloration due to the consumption of grape juice.

光固化时间对纳米填料复合树脂浸渍红葡萄汁颜色变化的影响

背景:复合树脂使用中的美学问题之一是颜色变化。本研究旨在比较纳米填料复合树脂在不同固化时间的红葡萄汁中浸泡前后的颜色变化。方法:采用18种直径为12mm，厚度为2mm的圆形复合树脂。将样本分为三组(n=6);A组固化20秒，B组固化30秒，C组固化40秒。固化后，37℃人工唾液浸泡24小时，用紫外-可见分光光度计测定。三组受试者在红葡萄汁中浸泡三天，并测量其最终颜色。数据分析采用单因素方差分析和事后LSD。结果:One Way Anova检验显示显著性值为0.000，即(p < 0.05)，说明各组之间存在显著性差异。然后对固化时间为20秒的复合树脂对固化时间为30秒的复合树脂进行事后LSD检验。结论:较长的固化时间可以防止纳米填料复合树脂因葡萄汁的消耗而变色。
