This volume provides a review of all types of glass-ionomer cements – from their uses, limitations, and advantages and disadvantages, to any problems associated with their use in modern dental practice. Detailed here are the physical, chemical, biological and clinical properties, with particular emphasis on clinical use on restorative and paediatric dentistry as well as orthodontics, prosthodontics, and endodontics. Questions about the efficacy of the newer-resin- and polyacid-modified materials are also addressed.
