Abstract

Color change is an undesirable but avoidable effect in composite resin. Limited research has been conducted on the effect of green tea solution on silorane- and methacrylate-based composite resins. In this study, we used 30 silorane- and methacrylate-based composite resin disks (shade A3) (6 mm in diameter and 2 mm in thickness) prepared from Filtek P90 and Filtek Z250. Specimens were divided into six groups (n = 5), and each group was immersed in three green tea solutions at different concentrations (1%, 2%, and 3%) for 6 hours. Color assessment was performed with a spectrophotometer based on CIE∗Lab theory, and results were subjected to statistical analysis using one-way ANOVA and independent t-test. Significant differences were observed in Δi∗ between the two composite disks after immersion in tea solutions (p < 0.05). Color change in silorane-based composite resin was higher than that in methacrylate-based resin; this color change was the highest when silorane-based composite resin was immersed in 3% green tea solution (ΔE = 3.85).
