Abstract
The color stability of acrylic denture teeth is important for the denture wearers as this reflects the overall appearance of their face. The aim of this study was to evaluate the color stability of the acrylic denture teeth when immersed in turmeric and black coffee solutions. Sixty acrylic denture teeth were used in this study. These teeth were divided equally into three groups: a control group (distilled water), turmeric and black coffee solutions. The color changes were recorded after Day 1, Day 7 and Day 15 of immersion period. The color measurements were performed by using Coral dental shade guide and a visible spectrometer. The visual assessment from the shade guide showed that the acrylic denture teeth immersed in turmeric solution had the most color change compared to the black coffee solution. The spectrometer analysis showed that the change in reflectance value was higher for acrylic teeth immersed in turmeric solution compared to black coffee solution, indicating more color changes in turmeric sample compared to black coffee sample. It was concluded that acrylic denture teeth showed less color changes when immersed in the black coffee solution compared to turmeric solution and that the amount of color change also increased proportionally with time.
