Research Abstract

The purpose of this study was to evaluate color change and stability against aqueous media (water and red tea) of three indirect composite materials (Epricord, Estenia, and Twiny) that were polymerized with different systems. Disk-shaped specimens were prepared with their proprietary polymerization systems or with a metal halide light polymerization unit (Twinkle X). The specimens were then immersed. Change in color from baseline (24 h) to 4 weeks was determined.
The results indicate that after tea immersion the Estenia material was less stable against color change than were the other two materials. The Twinkle X metal halide unit was suitable for polymerization of the three composite materials, using an exposure period of 60 s or longer.
