Glass-ionomer Cements - Current and Future Performance

Sponsored by: Cariology Research, Dental Materials, Dental Materials Journal

Description: The ability of glass-ionomers and resin-modified glass-ionomers to remineralise early caries lesions has been well established in laboratory studies. Technological innovations in recent years have provided dental professionals with a host of new tools to heal and restore carious lesions. Recent advances in these materials have allowed the introduction of techniques to ensure maximal preservation of dental tissues. This symposium includes the following topics: (1) The existing and recent literature on the clinical performance of resin-modified glass-ionomers, in terms of retention rates, marginal integrity and discolouration, will be examined and compared to other adhesive restorative materials wherever possible. It is intended that a review of their clinical performance will encourage discussion regarding the potential benefits, or otherwise, of their use. (2) The ‘Atraumatic Restorative Treatment’ (ART) technique approach will be described, including the development of ART sealants and ART restorations using different types of glass-ionomers (GICs), in a time-lag perspective (1986-2008). Restoration survival rate for both dentitions, wear patterns, antimicrobial action and future perspectives will be analysed. (3) The current understanding will be reviewed on the interactions between GIC and dentine, including the concept of ‘internal remineralisation’, as well as its interactions with the oral environment. (4) Current clinical evidence will be reviewed that does not consistently demonstrate that GICs prevent the progression of caries. Previous work will be discussed on the potential of amorphous calcium phosphates with casein phosphopeptide (CPP-ACP) to remineralise early enamel lesions. Laboratory tests will be presented on incorporating CPP-ACP into a high fluoride releasing GIC with enhanced potential for the GIC to reduce early enamel lesion progression. These topics together will provide a comprehensive review and discussion of the current status and future research directions of fluoride release. Sponsored by Elsevier Science.
