Physical properties of resin-modified glass-ionomers.
The physical properties and shear bond strength of two resin-modified glass-ionomers: RMGIs (FJL and VT) and as a control, a conventional glass-ionomer: CGI (FJ), were evaluated. Ninety percent of the setting shrinkage under dry conditions and nominal hygroscopic expansion in water during 360 h occurred within the first 24 h. The nominal hygroscopic expansion of CGI was 0.38% while the RMGIs de...
متن کاملPorosity of resin cements and resin-modified glass-ionomers.
PURPOSE To quantify the internal free surface in various resin cements and glass-ionomer-based materials. MATERIALS AND METHODS Materials tested were Nexus fluid (NXF) and viscous (NXV), Vitremer (VTM), Fuji II LC (FII), Vitremer Luting Cement (VLC), Dyract (DYR) and Compoglass (COM). Samples (n=5) were made of each material between two microscopic glass slides under same weight. With a trans...
متن کاملWater Absorption and HEMA Release of Resin-Modified Glass-Ionomers
OBJECTIVES The aim of this study was to evaluate the water absorption and the amount of hydroxyethyl metacrylate (HEMA) level released from various resin modified glass ionomer cements. METHODS Advance, Vitremer and Protec-Cem resin modified glass ionomer cements were used to evaluate the HEMA release. Ten specimens were fabricated from each cement in 10 x 1 mm height. Thirty specimens were i...
متن کاملResin modified glass-ionomers: strength, cure depth and translucency.
BACKGROUND According to the classification suggested by McLean, Wilson and Nicholson only three materials, currently marketed, fit the designation of resin modified glass-ionomers. These materials will undergo an acid/base setting reaction but also contain a limited quantity of a monomer that will polymerize as a result of irradiation. The quantity of polymer is limited to the extent that it wi...
متن کاملComparative Evaluation of Surface Hardness of Different Resin-Modified Glass Ionomers and a Compomer
Introdouction: Due to the practical problems and time restriction issues in treating dental problems in children, there is a noticeable demand for the application of a convenient handling restorative material with acceptable physical-mechanical properties. The aim of this investigation was to evaluate Vickers microhardness of four tooth-colored restorative materials as a determining mechanical...
