摘要:Abstract(#br)This review covers the adhesion of glass-ionomer cements, both conventional and resin-modified, to the enamel and dentine of the tooth. These materials are widely used in modern dentistry, and studies have shown them to bond particularly to the mineral phase of the t...

摘要:The ability of glass-ionomer dental cements to take up fluoride from a fluoridated mouthwash has been determined, and shown to vary somewhat with the degree of maturation (ageing). Three commercial conventional glass-ionomer cements were used to produce sets of five discs (6...

摘要:Abstract(#br)Previous studies have shown that glass-ionomers made from acrylic/maleic acid copolymers stored in water reach a maximum strength at about 1 week, and after 4 months have become significantly weaker. This finding, which contrasts with the behaviour of glass-iono...

摘要:Abstract(#br)Glass–ionomer cements, both self-hardening and resin-modified, have been shown to increase the pH of lactic acid solutions in which they are stored. Similar results have been obtained for a zinc phosphate and a zinc polycarboxylate cement. The pH was increased o...

摘要:Abstract(#br)The use of adhesive substances in dentistry, particularly in the restoration of decayed teeth, is growing. Adhesive materials are also used for securing brackets to the teeth in orthodontic treatment and for luting the form of artificial teeth known as jacket cr...

摘要:Abstract(#br)Studies of the setting of glass-ionomer cements have been carried out for over twenty years, and there is now a considerable body of information concerning the steps that lead to the conversion of a freshly mixed cement paste into a solid, durable dental restorative....

摘要:Abstract(#br)Organic compounds of phosphorus have been developed for a range of applications in clinical dentistry. These include dentine bonding agents, restorative materials and therapeutic agents, such as active ingredients in anticaries mouthwashes. A characteristic feature o...

摘要:Abstract(#br)Ag + - and Zn 2+ -exchanged zeolites and clays have been used as coatings and in composites to confer broad-spectrum antimicrobial properties on a range of technical and biomedical materials. 11 Å tobermorite is a bioactive layer lattice ion exchanger whose pote...

摘要:Abstract(#br)Specimens of an experimental glass-ionomer cement were stored in water (initial pH 5.9) and aqueous lactic acid (initial pH 2.7) for storage periods of 1 week up to 6 weeks. Change in mass, solution pH and fluoride release were measured at weekly intervals, and ...

摘要:Abstract(#br)Objectives(#br)This study was undertaken to gain a fuller picture of the interaction of resin-modified glass-ionomers with aqueous solutions in terms of water sorption, solution buffering and ion-release.(#br)Methods(#br)Two commercial materials were employed (F...
