In vitro assessment reveals CAD-CAM PMMA’s superior color stability in tea and turmeric, suggesting material choice affects aesthetic longevity.
The color stability of two provisional restorative materials, Computer-Aided Design-Computer-Aided Manufacturing (CAD-CAM) and Poly Methyl Methacrylate (PMMA) and light-cure composite resins, when exposed to various beverages is od interest. Samples were immersed in tea, coffee, turmeric solution, soft drink and artificial saliva, with color changes measured using a spectrophotometer at 15, 30 and 90 days. The results revealed that CAD-CAM PMMA demonstrated superior color stability, particularly in tea and turmeric, compared to composite material. Thus, the importance of material selection based on aesthetic longevity for provisional restorations is shown.
