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 کاملEffect of Powder/Liquid Ratio on Fluoride Release of Glass Ionomers
Objective: Evidence shows that the powder/liquid mixing ratio recommended by the manufacturers is often not respected when mixing the glass ionomer (GI) powder and liquid, yielding a GI cement with disproportionate powder/liquid ratio. Considering the confirmed effect of powder/liquid ratio on the GI properties, and more importantly, its fluoride release potential, this study aimed to assess ...
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 کاملDentin surface treatment and bond strength of glass ionomers.
This study evaluated the effect of dentin surface treatment on shear bond strengths of two light- cured glass ionomer restorative materials to dentin. Cylinders of Fuji II LC and VariGlass VLC were bonded to dentin surfaces that were untreated, treated with a 10% polyacrylic acid (GC Conditioner), or treated with a dentin bonding agent primer (Prisma Universal Bond 3 Primer). Specimens were the...
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...
