Purpose: This study was conducted to evaluate the effect of different staining solutions on color stability and surface roughness (SR) of Nano hybrid composite and acrylic denture teeth. Materials and Methods: Fifty specimens divided into two main groups. Each group divided into 5 subgroups each of 5 specimens of acrylic and composite teeth were used in this test. Teeth were immersed in four coloring solutions in addition to distilled water. Color measurements were erformed using spectrophotometer. Color change values were determined before and after immersion in the coloring solutions. The CIE L*a*b* color space was used to evaluate color differences. …
