Abstract

For the purpose of quantifying the staining rendency of light-cured glass ionomer cements and chemical-cured glass ionomer cements, Glass Ionomer specimens were stained with methylene blue and analyzed quantitatively with spectrophotometry. The data was processed and the result was as follows : 1. Chemical-cured glass ionomer cement showed higher color stability than light-cured glass ionomer cement with significance.(P<0.001) 2. In light-cured glass ionomer cement groups, Vitremer showed higher dye concentration of methylene blue than Fuji II LC. 3. In chemical-cured glass ionomer cement groups, Fuji II showed higher dye concentration of methylene blue than Ketac-fil.
