Özet
Aim The aim of this study was the in vitro effects of different beverages on the color stability of two different enamel-shade composites used in the outermost layer of the layering technique in the anterior region. Material and Methods Within the scope of the study, two different types of enamel-shade composites with nanofillers (3M Filtek Ultimate Enamel A2) and nanohybrid fillers (FGM Vittra APS Enamel A2) and 3 different beverage types (Nescafe Classic (Nestle, Bursa, Turkey), effervescent vitamin C (Redoxon, Bayer), Coca Cola and one control group (distilled water) were used. Total 80 discs, 40 of each composite, were prepared (10mm in diameter×2mm in thickness) and initial color measurements of all samples were made. The composite disks were randomly divided into 4 subgroups with 10 composite disks per beverage (n=10). All samples were kept in beverages for 4 weeks in total and color measurements were made along the study. Color change observed with Vita Easyshade (VITA Zahnfabrik, Bad Säckingen, Baden-Württemberg, Germany). In the change of color stability, the numerical values obtained with the spectrophotometer were analyzed with the CIEDE2000 formula. Results In both groups, there was a statistically significant difference in ΔE00 levels between beverage types(p=0.001; p<0.05). Coffee had significantly higher ΔE levels than distilled water , cola and vitamin C. In the coffee group, the ΔE 00 levels of the nanofil composite were significantly higher than those of the nanohybrid group (p=0.002; p<0.05). Conclusions In aesthetic restorations, color and color stability are very important for evaluating the success and clinical life of the restoration especially in enamel shade composites because they are the most affected by external discoloration. The reason for the difference in coloration between the composites can be that the nanofiller contents are more likely to be colored.
