The Effect of Various Beverages, Acidulated Phosphate Fluoride and Home Bleaching on the Color of Restorative Materials

Purpose: To investigate the effect of acidic beverage, home bleaching, acidulated phosphate fluoride (APF), and immune-boosting beverage with Sambucus Nigra on color of restorative materials. Materials and Methods: 84 nanohybrid composite resin (NCR) and CAD-CAM feldspathic ceramic (FC) specimens (1.5 mm-thick) were prepared. The specimens were first subdivided into FCA, FCB, NCRA, NCRB, then distilled water (DIS), lemon juice (LEJ), home bleaching (BA). Measurements were taken after 2 weeks of applications (App1). After App1, FCA and NCRA were kept in Sambucus Nigra beverage (SAM), while FCB and NCRB were kept in SAM after APF (APFSAM). Measurements were taken on 12th and 24th day (App2). The effects on color of App1 and App1+App2 were analyzed by ANOVA and Bonferroni tests. Results: For App1, the effect of material, App1 and material-App1 on color was statistically significant (p
