| Abstract | ||
| Objective: The aim of the study is to evaluate the surface topography (Polished vs. Non-polished) and color stability of different provisional materials: 1) Bis-acryl Composite (System C&B – IvoclairVivadent); 2) Bis-acryl Composite (ProTemp IV – 3M ESPE); 3) Bis-acryl Composite (Success CD – Promedica); 4) Polymethyl Methacrylate (Trim II – Bosworth); and 5) Light-cure Polymethyl Methacrylate (UniFast TRAD – GC Europe) immersed in commonly used beverages. Material and Methods: The color change value of each specimen after immersion in different beverages i.e. 1) Coffee with artificial saliva; 2) Tea with artificial saliva; 3) Cola with artificial saliva; 4) Apple juice with artificial saliva; and 5) Saline with artificial saliva was measure using spectrophotometer with CIE LAB system before and after immersion at 2 days, 1, 2 weeks, and 1 month. Results: ProTemp IV was found to be the most color stabile material, followed by System C&B, Success CD, Trim II, and UniFast TRAD respectively. It was found that coffee had the most staining ability, followed by tea, cola, and apple juice. Conclusion: Bis-acryl composites showed the highest color stability values (ProTemp IV, System C&B, and Success CD), followed by Polymethyl Methacrylate (Trim II), then light cured polymethyl methacrylate (UniFast TRAD). Polishing decreases the color changing values of the provisional materials. Coffee had the most color changing effect. | ||
