Glass ionomer cements (GICs) are important restorative materials that are frequently preferred in both primary and permanent teeth. The aim of this study was to investigate the effect of thermo-light curing on the surface microhardness and fluoride ion (F - ) release of the materials during the curing reactions of high -viscosity GICs. In our study, Equia Fil (EQGC), Fuji IX GP Extra (FGP-GC), and Fuji IX Capsule (FC-GC) were prepared in accordance with the manufacturer's instructions, and for 60 and 90 seconds during curing Woodpecker LED -C (WL), GC D -Light Pro (GLC) and BlueLuxcer M-855 Halogen Curing Light (HALO) light instruments formed the experimental groups, and self -curing glass ionomer cement samples formed the control groups. VHN and Frelease values of both groups were evaluated on 1st day, 1st week, 1st, 3 rd , and 6th months. The Jamovi (Version 1.0.4) program was used for statistical analysis. Significant difference was analyzed by the Tukey's post hoctest (a = 0.05). In the 1st month, EQ exhibited significantly higher microhardness than FC (p<0.05) but not with FGP (p>0.05). All materials exhibited higher microhardness during 1st day than in other periods (p<0.05). In terms of Frelease, there were significant differences between materials on the 1st day (p<0.05). EQ, FC, and FGP exhibited higher Frelease, respectively. In the 1st, 3rd, and 6th months, EQ exhibited released significantly higher Fsignificantly (p<0.05), whereas this amount was similar between FC and FGP (p>0.05). Within the limitations of this study, it can be concluded that thermo-light application does not cause unacceptable long-term changes in the physical and chemical properties of materials.
