The evaluation of microhardness of different restorative glass ionomer cements

AUTHOR(S): Elif Ok, Hakan Kamalak, Canan Aksu Canbay and Oktay Yiğit
ABSTRACT:The purpose of this study is to compare the microhardness 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 Vickers hardness number was measured on the surface in contact with the stainless steel sheet using a micro-indentation tester (Emco Test Durascan) with a 100N. Statistical analysis was performed on the obtained data (Wilcoxon Signed Ranks Test, ANOVA, Bonferroni). Results: Significant difference was determined between microhardness values, statistically (p <0,05). While microhardness values are highest in F9S, GCP was at least as well. Conclusion: According to microhardness findings, statistically significant hardness differences were observed in glass ionomer cements. However, microhardness values similar to composite materials were obtained in some groups.
