The status of glass-ionomers as a restorative material continues to improve along with their reputation for longevity. They have now been shown to be moderately bioactive, so they have a very important role to play in remineralizing tooth structure and helping to heal carious lesions. This comprehensive clinical guide to their uses in operative dentistry has been updated throughout and remains the leader in the field. Graham J Mount AM, BDS, DDSc, FFACDS, FICD, FADI, has spent fifty years in private practice based in Adelaide, Australia. Since the formal introduction of glass-ionomer cements in 1976, Dr Mount has been closely involved with their development in research as well as through clinical trials. His other publications include Preservation and Restoration of Tooth Structure (1998). Comments on the second edition: "All the techniques are there, superbly illustrated with carefully reproduced colour photographs backed up by a lively and highly readable text." DENTAL UPDATE
