The aim of this study was to evaluate the color stability of two composite resins after exposure to beverages such as Cola, Pepsi, Red Bull, and distilled water after 15 days.
The color stability of a microhybrid and nanohybrid composite was evaluated after storage in distilled water, Coca-Cola, Pepsi, and Red Bull for 15 days. Color measurement was done using a reflectance spectrophotometer based on the CIE Lab* color scale.
All tested resin composites showed color change after a period of 15 days. One-way analysis of variance and Tukey post hoc were done to assess the significance of color change within the group and an independent t-test was done to assess the change between micro and nanohybrid composite. Among the resin composites studied, microhybrid composite was found to be more color stable. The microhybrid and nanohybrid composite discolored most in Coca-Cola and Pepsi. In both groups, distilled water showed very less color change.
Every endeavor should be undertaken to minimize the potential for discoloration in composite restorations by employing meticulous polishing techniques and also to use newer composite material with submicron particles. Furthermore, it is imperative to educate patients about the likelihood of the restoration being susceptible to staining from various beverages.
本研究旨在评估两种复合树脂在暴露于可乐、百事可乐、红牛和蒸馏水等饮料15天后的颜色稳定性。
将一种微混合复合树脂和一种纳米混合复合树脂分别储存在蒸馏水、可口可乐、百事可乐和红牛中15天，然后评估其颜色稳定性。使用基于CIE Lab*色标的反射分光光度计进行颜色测量。
所有测试的树脂复合材料在15天后均出现颜色变化。进行单因素方差分析和Tukey事后检验以评估组内颜色变化的显著性，并进行独立t检验以评估微混合复合树脂和纳米混合复合树脂之间的变化。在所研究的树脂复合材料中，发现微混合复合树脂颜色更稳定。微混合复合树脂和纳米混合复合树脂在可口可乐和百事可乐中变色最多。在两组中，蒸馏水的颜色变化非常小。
应尽一切努力通过采用精细的抛光技术以及使用具有亚微米颗粒的新型复合材料来尽量减少复合树脂修复体变色的可能性。此外，必须告知患者修复体可能会被各种饮料染色的情况。
