Abstract

Aim: The aim of this study is to investigate the effect of different ground-based coffee types on the color change of nanohybrid and bulk-fill composites.


Methodology: A total of 80 disk-shaped samples were made using Teflon molds (5 mm in diameter and 8 mm thick) and two types of A2 resin with nanohybrid (Tetric N Ceram Ivoclar Vivadent, Schaan, Liechtenstein) and bulk-fill (Filtek Bulk-Fill, 3M ESPE, St. Paul, MN, USA) structures. All samples were finished and polished with four-stage (thick, medium, fine, and superfine) polishing disks (Sof-lex, 3M ESPE, St. Paul, MN, USA) and kept at 37°C for 24 hours. Color measurements of the samples were performed using a spectrophotometer (Vita Easy Shade, Vita ZahnFabrik, Bad Sackingen, Germany) and were divided into subgroups: the control group, filter coffee, Turkish coffee, espresso, and Mırra (n = 8). Distilled water was used as a control. Prepared coffees were added to the microcentrifuge tubes and refreshed daily during the 14-day exposure period. ΔE values were calculated for each material. Statistical analyses were performed using one-way variance analysis and Tukey multiple comparisons (p = 0.05).


Results: There was no significant color change for either the nano-fill or bulk-fill composite groups in the control group samples (p>0.05). Filter coffee was found to be the most effective colorant coffee type for both composites (p < 0.05). Among the coffee types, Mırra caused the least coloration for both composites.


Conclusion: The consumption of two or more cups of coffee per day, especially filter coffee, can cause color changes in both conventional and bulk-fill composites, and it should be considered an important factor in aesthetic problems with dental restorations.
