Abstract

Aim: The purpose of this study was to evaluate and compare the color stability of commonly used three different provisional restorative materials after immersion in four different media and accelerated aging. Materials and Methods: In this study 3 commercially available provisional restorative materials (DPI, Cooltemp, and Protemp) were evaluated for color stability. A total of 48 disc-shaped specimens with dimensions of 10 mm diameter and 2 mm thickness were prepared. The specimens were then subjected to aging in artificial saliva. Four different staining solutions namely tea, turmeric, coca-cola, and mouthwash were prepared for evaluation of color stability of the specimens and were immersed in them for 21 days. Color measurements were recorded before and after immersion. Results: The results of this study showed that maximum difference of light transmittance (%T) was seen in Group D (DPI, polymethylmethacrylate [PMMA]). Hence, Group D showed the least color stability whereas Group P (Protemp and bis-acryl composite) showed the highest color stability. For staining solutions, the results reveal that maximum color change was seen after immersion in turmeric. Conclusion: All three provisional restorative materials exhibited statistically significant color change after exposure to staining solutions. DPI (PMMA) showed the least color stability in all immersion media.
