The Effect of Traditional Regional Beverages on the Color Stability of PMMA Denture Base Materials

Aim: The color stability of PMMA-based denture base materials can be affected by personal habits, such as hygiene and beverage consumption. Color stability of denture bases is a crucial esthetic criterion for long-term success. In our study, the effect of three different local drinks consumed in the Thrace region on the color of base materials was measured. Material and Methods: In this study, samples produced from three different PMMA-based pink acrylics (Meliodent Rapid Repair, Imicryl IQ15, Duracryl Heat Cure) with the traditional muffle method were immersed in four different solutions (Distilled water (ontrol Group), Chasteberry juice, Plum Juice, Black Mulberry Juice) ( n=10) was kept for 21 days. Color measurements were made with a spectrophotometer on days 0-7 and 21, and color change values (ΔE00) were calculated. One-way ANOVA and Tukey HSD multiple comparison test were used for statistical analysis of color changes (p=0.05). Results: The findings showed that on the seventh day, the coloration caused by plum juice in samples was significantly higher than that of distilled water (p=0.002). There was no difference in color change in other drinks, materials and times (p>0.05). It was observed that on the seventh and twenty-first days, the color change values in all beverages remained below the visual perceptible limit (ΔE00<1.72). Conclusion: PMMA-based base materials show color change as a result of interaction with beverages, and this change varies depending on the waiting time, acrylic brand and type. As a result, color changes between base materials and beverages were not clinically significant.
