The clinical use of glass-ionomer cements.

摘要: The use of glass-ionomer cements in clinical dentistry has expanded greatly over the last decade. Their treating early carious or erosion lesions been investigated widely and established techniques include fissure filling, restoration without cavity preparation, internal tunnel restoration. Because their adhesion to moist tooth structure, biologic compatibility, fluoride release, increasing also made anticariogenic properties geriatric patients. Glass-ionomers have proved very successful as dentin substitutes for attaching composites enamel involving risk pulpal damage deeper cavity. deficiencies are well known, including lack toughness, water sensitivity, low abrasion resistance, porosity, leading poor surface polish. Solving these problems is formidable because inherently strength related content. clinician should be aware stay within parameters outlined this article. In particular, success depends on protection cement from hydration dehydration current light-cured bonding agents largely solved problem. future probably lies using laminate which materials that attach form a seal can covered by tougher harder veneers, thus mimicking structure tooth. It possible will developed lines polyelectrolyte higher molecular weight polymers used conjunction with contain photoinitiators effect light curing toughen matrix. addition, possibility developing laboratory-cured inlays porosity reduced considered.
