Abstract

Abstract: Objective: To evaluate the color stability of novel bulk‐fill composite resins. Materials and Methods: Color measurements of a nanohybrid composite resin (Z550) and 3 bulk‐fill composite resins (BLK, AFX, XTF; n = 45) were performed before polymerization. After polymerization, color measurements were repeated and specimens were immersed in distilled water or red wine, or coffee. Color change [CIEDE2000 (Δ E 00 )] was calculated after 24 h, 1 and 3 weeks. Data were analyzed with Kruskal‐Wallis, Mann‐Whitney U and Wilcoxon tests (α = 0.05). Results: Color changes observed after polymerization were significant for all groups. Color changes observed in distilled water for Z550 and AFX were significant. Color changes after stored in red wine and coffee were significant for all groups. Bulk‐fill composite resin color change increased over time for all groups in red wine and coffee ( P < .05). Conclusion: Polymerization significantly changed the color of nanohybrid composite resin and bulk‐fill composite resins. AFX had the highest color change in distilled water. The color of tested bulk‐fill composite resins significantly changed after immersion in beverages and over time. Color change observed with the nanohybrid composite resin after 1 week was stable. CLINICAL SIGNIFICANCE: Clinicians should keep in mind that tested composite resins may change color when exposed to water and significantly change color immediately after they are polymerized. In addition, the color change continues over time should the patient is a coffee and/or red wine consumer.
