Incorporation of Hydroxyapatite-Silica Nano-Powder for Enhancement of Glass Ionomer Cement (GIC)
Glass Ionomer Cement (GIC) is one of the most popular materials among the available dental restorative materials. They have desirable properties like direct adhesion to the tooth structure, thermal compatibility [1] and good biocompatibility [2,3]. Despite these advantages, brittleness, low tensile and flexural strengths have limited their use only to certain low stress-bearing sites. As such, ...
متن کاملEffect of Incorporation of Nano-Hydroxyapatite and Nano-Zinc Oxide in Resin Modified Glass Ionomer Cement on Metal Bracket Debonding
Background and Aim: Use of fluoride releasing materials to decrease the risk of demine-ralization around orthodontic brackets would be reasonable as an adhesive for bracket bonding only if they provide acceptable shear bond strength (SBS). The aim of this study was to evaluate the SBS of resin-modified glass ionomer cements (RMGICs) modified by nano-zinc oxide (NZnO) and nano- hydroxyapatite (N...
متن کاملIncorporation of bioactive glass in calcium phosphate cement: An evaluation.
Bioactive glasses (BGs) are known for their unique ability to bond to living bone. Consequently, the incorporation of BGs into calcium phosphate cement (CPC) was hypothesized to be a feasible approach to improve the biological performance of CPC. Previously, it has been demonstrated that BGs can successfully be introduced into CPC, with or without poly(d,l-lactic-co-glycolic) acid (PLGA) microp...
متن کاملEffect of adding spherical silica filler on physico-mechanical properties of resin modified glass-ionomer cement.
This study investigated the effects of spherical silica fillers on the physical and mechanical properties of resin-modified glass-ionomer cement (RMGIC). Specimens were fabricated by mixing untreated (UF) or silanized (SF) spherical silica filler into the powder of a commercially prepared RMGIC. The original RMGIC and a preparation containing 20 wt% spherical silica filler were also examined wi...
متن کاملEffect of Nanoclay Dispersion on the Properties of a Commercial Glass Ionomer Cement
Objective. The reinforcement effect of polymer-grade montmorillonite (PGV and PGN nanoclay) on Fuji-IX glass ionomer cement was investigated. Materials and Method. PGV and PGV nanoclays (2.0 wt%) were dispersed in the liquid portion of Fuji-IX. Fourier-transform infrared (FTIR) spectroscopy and gel permeation chromatography (GPC) were used to quantify acid-base reaction and the liquid portion o...
