Dental cements, direct filling resins, composite and adhesive restorative materials: A resume

Abstract

This resume concerns experimental and commercial dental cements and restorative and adhesive materials usually containing nonmetallic inorganic components, the biocompatibility of the above with oral tissues, proposed methods of bioevaluation, the oral environment, the nature of the hard tooth tissue, cavity treatment, agents for bonding the restorative material to the tooth, and 112 references. The cements include those based on (C‐1) zinc oxide‐eugenol with additives such as zinc acetate, rosin, polymers and most important o‐ethoxybenzoic acid (EBA); (C‐2) metallic oxides‐phosphoric acid; (C‐3) acid phosphate salts‐water; (C‐4) aluminosilicate glass‐phosphoric acid; (C‐5) zinc oxide‐polyacrylic acid; (C‐6) methyl methacrylate‐poly‐(methyl methacrylate) with or without inorganic fillers. Direct filling resins (C‐6) without filler and composite restorative materials (C‐6) with filler are based on acrylic resins or reaction products of acrylic (methacrylates) with other resins. Coupling agents include cyanoacrylates, epoxy‐acrylic adducts and polyurethanes. The 10 tables give composition, values for pertinent physical properties or dental requirements. (C‐2) Dominates the cements but (C‐1) with (EBA) and (C‐5) which has some adhesion to hard tooth tissues and stainless steel may displace (C‐2). (C‐4) Restorative materials are anticariogenic and widely used but are being supplanted by composite restorative materials.

The sensitizing potential of di‐(meth) acrylates based on bisphenol A or epoxy resin in the guinea pig

“…BIS-GMA is the resin matrix in almost all of the commercially available composite restorative materials used today (26). Polymerization of these materials is either activated chemically (e.g.…”

Application of HS-SPME in the determination of potentially toxic organic compounds emitted from resin-based dental materials

“…[1][2][3] However, a number of different filling materials are presently available for tooth restorations. [4][5][6][7][8] The four main groups of dental filling materials used by dentists over about 30 years are the glass-ionomer cements (GICs), also named conventional glass-ionomer cements, resin-based composites, resin-modified glass-ionomer cements (RMGICs) and polyacid-modified resinous composites (compomers). The frequently used restoratives in dental practice are the resin composites.…”

Clinical Evaluation of Indirect Particle‐Filled Composite Resin CAD/CAM Partial Crowns after 24 Months

“…Composite resin materials have been shown to have a high clinical success rate in restorative therapy. 1,2 Clinical indications for composite resin materials are limited because of material characteristics such as polymerization shrinkage and abrasion coefficient. 3 Indirect restorations have been shown to strengthen the remaining tooth substance and might be preferable if the tooth defect exceeds a certain dimension.…”
