ABSTRACT:The purpose of this study is to compare the thermal conductivity properties of glass ionomer cements in different contents. Method: The study group included five different glass ionomer cements; EQUIA Forte Fil (GC, Tokyo, Japan, EQF), Fuji II LC Light-Cured Glass-Ionomer Cement for Restorative Filling (GC Corp, Tokyo, Japan, F2S), Fuji IX Conventional glass ionomer Cement for Restorative Filling (GC Corp, Tokyo, Japan, F9S),Glass carbomer (Glass Carbomer, GCP), Ionoseal (Glass ionomer cement, VOCO, Cuxhaven, IOS). They were filled in teflon molds (height: 4 mm, width: 6 mm) and irradiated for 20 s chemically or by LED device. The heat conductivity of the samples was analyzed by the home made thermal conductivity measurement system. Five materials showed clinically acceptable values in terms of thermal conductivity. The results we observed in this study are in agreement with literature.
