Abstract:The purpose of this study was to evaluate the water absorption, solubility, microhardness, surface roughness, zinc release, fluoride release and uptake of newly developed zinc containing encapsulated conventional glass ionomer cement ChemFil Rock (Dentsply De-Trey, Konstanz, Germany) and encapsulated conventional glass ionomer cement GC Fuji IX GP Normal (GC Corporation, Tokyo, Japan) and effects of nanofilled light-cured coating material Equia-Coat (GC Corporation, Tokyo, Japan) on these properties in vitro. The specimens were divided into four groups, GC Fuji IX GP Normal, GC Fuji IX GP Normal+Equia-Coat, ChemFil Rock, ChemFil Rock+Equia-Coat. For solubility and water absorption tests, samples were prepared in metallic molds with 15x1mm, calculated according to the change of mass in distillated water. For microhardness test, samples were prepared in polyether molds with 4x2mm, analyzed using Vickers Hardness Tester. For surface roughness test, samples were prepared in metallic molds with 3x3x2mm, analyzed using profilometer. For zinc release test, samples were prepared in metalic molds with 10x2mm, analyzed using atomic absorption spectrophotometer. For fluoride release and uptake test, samples were prepared in metallic molds with 9x3mm, analyzed using ion selective electrode method. As a result, ChemFil Rock showed lower water absorpsion, solubility, fluoride release and uptake values and there is no difference between microhardness and surface roughness values of ChemFil Rock and GC Fuji IX GP Normal. ChemFil Rock only showed higher zinc release values and ChemFil Rock requires surface protection to decrease water absorption and surface roughness.
