Abstract
BACKGROUND: Glass ionomers are materials formed by apolymer matrix cross-linked with ionic bonds to which glassreinforcing particles are incorporated. Currently they arewidely used in dentistry, available with different consistenciesand viscosities that differ depending on the use, rangingfrom conservative, prosthetic and orthodontics. They havegood adhesion to dental structures and a compression resistancevery similar to dentin. They constitute a layer of elasticmaterial able to dissipate the mechanical and thermal stressesto which they are subjected. The aim of the present study wasto evaluate the operational possibilities of these materials andspecifically the importance that these materials play in thetreatment of caries pathology in patients with autism spectrumdisorder syndromeMETHODS: The methods used for this work were a searchfor articles in English and Italian, published on PubMed from1990 to 2016, using the following keywords: “Glass IonomerCements”, “Dental Restoration Repair”, “Dental RestorationFailure”, “Dental Restoration, Temporary”, “DentalRestoration, Permanent”.
