Five-year color changes of light-cured resin composites; influence of light-curing times

摘要

Objectives: The purpose of this study was to investigate the influence of light-curing times on the color changes of light-cured resin composites, over specified periods of time. Methods: Silux Plus (3M Dental Products) light-cured resin composite disks (shades; U, Y, DY, L, G, UO, Yo), 10 mm in diameter and 1 mm in thickness were prepared with 20, 40, and 120s of light exposure through a 1 mm thick glass plate. The specimens were stored in artificial saliva at 37 deg. C.
