description AIM AND OBJECTIVE: To evaluate the in vitro effect of red wine on color stability of three different esthetic restorative materials such as nanohybrid composites, conventional restorative glass ionomer cement (GIC), and feldspathic porcelain. MATERIALS AND METHODS: The color stability of test materials was determined using a spectrophotometer. A total of 30 specimens were prepared (10 from each) from each material on a round metal mold (11 mm diameter and 2 mm deep). The specimens were stored in distilled water at 37°C for 24 h for rehydration. Baseline color of all groups was recorded. Specimens of each material were divided into 2 groups of 5 specimens each (n = 5). Two groups include red wine and distilled water as a control. Specimens were then immersed in 25 ml of red wine for 20 min at room temperature everyday for 28 days. Specimens were kept in distilled water for the remaining part of days. After the completion of immersion sequence, the specimens were rinsed with distilled water and blotted dry. Postimmersion color of all specimens was then recorded. Data were analyzed by two-way ANOVA and post hoc Tukey's test. RESULTS: The color stability is significantly higher in porcelain than composite and conventional GIC. CONCLUSION: Within the limitations of this study, it was concluded that the porcelain shows less discoloration than composite and conventional restorative GIC.
