Effects of Different Beverages on Color Stability of Bulk-Fill Restorative Materials

Purpose: The aim of the study is to evaluate color stability a conventional composite resin and bulk-fill resins.
 Material Methods: A total 120 samples 10 mm diameter 2 thickness were prepared from three (Beautifil Bulk-Fill, Filtek One Tetric N-Ceram Bulk-Fill) one (Z250) light cured. Initial measurements made with spectrophotometer. Samples for each randomly divided into 3 groups (black, kombucha matcha tea) (n = 10). kept in solutions 12 days, measurement was repeated. values ΔL, Δa, Δb ΔE00 calculated. SEM images taken selected sample group. Two-way analysis variance (ANOVA) Bonferroni correction used parameters.
 Results: Beautifil showed greatest change all E00, Δb., had highest after Beautifil, respectively, there no difference between Z250 N-Ceram. lowest ΔL value belonged composite, One. Δa and, Z250. 
 Conclusion: Beverages can negatively affect surface properties resins terms stability.
