Aim: This study aims to provide valuable insights into the effect of waterpipe exposure on the color change of CAD/CAM plastic dental materials. Method: Three types of crowns were used in this study for color change after they were exposed to waterpipe whole-body exposure machine for 6-months. The materials are PEEK, Zircon, and Acrylic denture teeth. PEEK and Zircon were prepared using Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) while Acrylic teeth were taken from a kit. Results: The findings of this study are important for clinicians. Color changes were measured using a colorimeter. The lightness values generally decreased after exposure across all materials, PEEK, Zircon, and Acrylic denture teeth. The differences in lightness values (L*) among the materials were statistically significant at all exposure durations (p < 0.001). Redness values (a*) and yellowness values (b*) have been investigated with significant differences in redness between PEEK, Zircon, and Acrylic denture teeth (p < 0.001). While yellowness values (b) fluctuate, with no significant 4difference in yellowness among materials. The AE values were reported for each material, and the results show a specific extent of color change after exposure to waterpipe smoke over different periods. The results showed that despite having the highest baseline AE values, Acrylic exhibited relatively minor color changes after exposure. Chroma values for all materials tend to fluctuate with exposure time with no clear increasing or decreasing trend. Conclusion: The exposure to waterpipe smoke showed that PEEK, Zircon, and Acrylic denture teeth are susceptible to staining to different extents depending on the duration of exposure.
