Abstract

AIM

THIS STUDY EVALUATED THE COLOR STABILITY OF FOUR PROVISIONAL MATERIALS: 1) Poly-methyl methacrylates (DPI); 2) Bis-acryl composite (ProtempTM II - 3M ESPE); 3) Bis-acryl composite (Systemp® c and b - Ivoclar Vivadent) and 4) Light polymerized composite resin (Revotek LC- GC).

MATERIALS AND METHODS

The color and color difference of each specimen after immersion in different staining solutions i.e. 1) tea and artificial saliva, 2) coffee and artificial saliva, 3) Pepsi and artificial saliva, 4) turmeric solution and artificial saliva was measured using reflectance spectrophotometer with CIELAB system before immersion and after immersion at 2, 5 ,7 , 10 and 15 days.

RESULTS

Revotek LC- GC (light polymerized composite resin) was found to be the most color stable provisional restorative material followed by Protemp II (Bis-acryl composite), Systemp (Bis-acryl composite) and DPI (Methylmethacrylate resin). Turmeric solution had the maximum staining potential followed by coffee, tea and Pepsi.

摘要

目的

本研究评估了四种临时材料的颜色稳定性:1)聚甲基丙烯酸甲酯(DPI);2)双丙烯酸复合树脂(ProtempTM II - 3M ESPE);3)双丙烯酸复合树脂(Systemp® c和b - Ivoclar Vivadent);4)光固化复合树脂(Revotek LC - GC)。

材料与方法

使用带有CIELAB系统的反射分光光度计,在浸泡于不同染色溶液(即1)茶和人工唾液、2)咖啡和人工唾液、3)百事可乐和人工唾液、4)姜黄溶液和人工唾液)之前以及浸泡后2、5、7、10和15天时,测量每个样本的颜色和色差。

结果

发现Revotek LC - GC(光固化复合树脂)是颜色最稳定的临时修复材料,其次是Protemp II(双丙烯酸复合树脂)、Systemp(双丙烯酸复合树脂)和DPI(甲基丙烯酸甲酯树脂)。姜黄溶液的染色潜力最大,其次是咖啡、茶和百事可乐。
