How the Translucency and Color Stability of Single-Shade Universal Resin Composites Are Affected by Coffee?

Abstract

Objective: The aim of this study was to examine how staining with coffee affects single-shade universal resin composites and a multi shade universal resin composite in terms of translucency and color stability.Method: Five different resin composites (Omnichroma, Vittra APS Unique, Zenchroma, Charisma Diamond One, and Neo Spectra ST) were used to create 50 samples (n=10). A spectrophotometer was used to record translucency parameter (TP00) and color changes ( ΔE00) at baseline and after immersion in coffee for 24 h. Color differences were calculated according to CIEDE2000. Data analysis was performed using one-way ANOVA and the paired-samples t-test. Results: After immersion of resin composite samples in coffee for 24 h the Vittra APS Unique group showed the highest ΔE00 value and the Neo Spectra ST group the lowest (P<0.001). At baseline, low TP00 values were observed in Neo Spectra ST and Charisma Diamond One and high TP00 values in Omnichroma and Vittra APS Unique (P<0.001). After being stained with coffee On day 1, low TP00 values were recorded in Neo Spectra ST and Charisma Diamond One, and high values TP00 in Omnichroma and Zenchroma (P<0.001).Conclusion: Short-term staining resulted in less color change in the multi shade universal resin composite than in the single-shade universal resin composites. ΔE00 and TP00 values varied between the single-shade universal resin compositesKeywords: Color Stability, Multi shade Universal Resin Composite, Single-Shade Universal Resin Composite, Translucency Parameter
