Abstract: Objectives: The purpose of this study was to evaluate the colour stability of provisional restorative materials exposed to different beverages at varying time intervals. Methodology: Forty samples of each materials ( Protemp 4 and Revotek LC) were prepared with a diameter of 10mm and 3mm thickness. After immersion in staining solution of synthetic saliva (control), synthetic saliva and green tea, synthetic saliva and red wine, synthetic saliva and cold beverage; on 7th and 30th day color measurement was done using Spectrophotometer Statistical analysis: Statistical analysis were done using Independent-t test and one way ANOVA. Result: Statistically significant color change was noticed in Red wine on comparing between Protemp 4 and Revotek LC provisional materials at the end of 7th and 30th day. Conclusion: Maximum discoloration was seen in synthetic saliva & red wine solution for all the two materials. Protemp 4 is the best material out of both, if provisional restoration has to given for longer duration in the esthetic region. .
