The Effect of Different Staining Solutions on the Color Stability of Temporary Crown Materials

Abstract

Background: The esthetic expectations of patients are increasing by the day. That is why it is important to minimize the color changes in the oral cavity in both the temporary and permanent restorations.

Aim: This study was carried out to compare the time-dependent color changes of polished and  unpolished temporary crown materials prepared by different methods in various solutions.

Materials and Methods: Half of the two different temporary  restoration materials prepared with a diameter of 10 mm and a thickness of 2 mm were polished, and half were not polished. The ΔE* values of the  samples kept in various solutions were recorded. Data were statistically evaluated by using variance analysis (ANOVA) and a Tukey HSD multiple  comparison test.

Results: It was determined that the material type, the solution, the interaction between the material types and the surface treatment,  and the interaction between the surface treatment and the solution were statistically significant for color change (p < 0.001).

Conclusion: The most  significant color change in the inter‑material evaluation was observed in chemically polymerized polymethyl methacrylate. In the evaluation between  beverages, the highest color change was found in sugared coffee, and the lesser color change was observed in polished samples
