“…Moshaverinia et al [7] have reviewed the literature describing the trends of modifying the polymer phase in GPCs. They focused on the advantages and disadvantages of various PAA-based polymers currently used in GPC systems (including new acrylic acid copolymers, amino acid containing polyelectrolytes, N-vinylpyrrolidone and N-vinylcaprolactam modified terpolymers).…”

“…The reaction between both components results in a composite cement material consisting of reacted and unreacted glass particles embedded in a polysalt matrix [2][3][4]. GPCs are used in dentistry due to a selection of clinical advantages as follows [2,[5][6][7][8][9]: (a) Single-step adhesion characteristics of both enamel and dentine. These features have made them attractive candidates for expanded applications in hard tissue repair.…”

Abstract Glass polyalkenoate cements (GPCs) have been used in dentistry for over 40 years. These novel bioactive materials are the result of a reaction between a finely ground glass (base) and a polymer (acid), usually poly(acrylic acid) (PAA), in the presence of water. This article reviews the types of PAA used as reagents (including how they vary by molar mass, molecular weight, concentration, polydispersity and content) and the way that they control the properties of the conventional GPCs (CGPCs) formulated from them. The article also considers the effect of PAA on the clinical performance of CGPCs, including biocompatibility, rheological and mechanical properties, adhesion, ion release, acid erosion and clinical durability. The review has critically evaluated the literature and clarified the role that the polyacid component of CGPCs plays in setting and maturation. This review will lead to an improved understanding of the chemistry and properties of the PAA phase which will lead to further innovation in the glass-based cements field.

Abstract:Objective: This study deals with the effect of phosphoric acid etching and conditioning on enamel micro-tensile bond strengths (μTBSs) of conventional and resin-modified glass ionomer cements (GICs/RMGICs). Methods: Forty-eight bovine incisors were prepared into rectangular blocks. Highly-polished labial enamel surfaces were either acid-etched, conditioned with liquids of cements, or not further treated (control). Subsequently, two matching pre-treated enamel surfaces were cemented together with one of four cements [two GICs: Fuji I (GC), Ketac Cem Easymix (3M ESPE); two RMGICs: Fuji Plus (GC), RelyX Luting (3M ESPE)] in preparation for μTBS tests. Pre-treated enamel surfaces and cement-enamel interfaces were analyzed by scanning electron microscopy (SEM). Results: Phosphoric acid etching significantly increased the enamel μTBS of GICs/RMGICs. Conditioning with the liquids of the cements produced significantly weaker or equivalent enamel μTBS compared to the control. Regardless of etching, RMGICs yielded stronger enamel μTBS than GICs. A visible hybrid layer was found at certain enamelcement interfaces of the etched enamels. Conclusions: Phosphoric acid etching significantly increased the enamel μTBSs of GICs/RMGICs. Phosphoric acid etching should be recommended to etch the enamel margins before the cementation of the prostheses such as inlays and onlays, using GICs/RMGICs to improve the bond strengths. RMGICs provided stronger enamel bond strength than GICs and conditioning did not increase enamel bond strength.

Acrylic acid copolymers bearing radically polymerizable methacrylic and itaconic moieties are synthesized. Starting from copolymers of tBA and APVE, prepared at different ratios, methacrylic or itaconic amides are obtained via polymer‐analogous reaction. After acidic elimination of isobutylene, polymers with free carbon acids and staggered reactivity can be prepared. Varying amounts of attached acrylamide moieties allow the adjustment of network densities. Rheological properties in HEMA/water matrices during curing are evaluated.
