Objective: To evaluate the color stability of different temporary prosthetic restorative materials (acrylic and bis-acrylic resins) immersed in different solutions. Methods: The specimens were prepared for each of three materials, self cure poly methyl methacrylate, heat cure poly methyl methacrylate, and autopolymerized bis-acryl resin material. The baseline colour values were measured with a colorimeter according to the CIE a’b’ color scale. After the first measurement, specimen were placed in staining solution coffee and artificial saliva for 5 days and the second colorimetric readings were taken at 5 days. Results: Data were analyzed statistically by one way ANOVA tests and Tukey multiple comparison tests. After the 5day immersion period, the post hoc analysis revealed that Bis-acryl resin material has the highest ?E values. Conclusions: Acrylic resin presented greater color stability when compared with bis-acrylic resins. Bis-acryl temps or self cure temporisations can be provided for the prepared tooth as temporaries for 3 or less than 3 days, whereas if the definitive restoration requires longer period of time for construction, i.e. 5 days or more, then heat cure temporisation materials are indicated considering the amount of colour changes.
