Glass ionomer cements have been used in pediatric restorative dentistry for 20 years. Their usefulness in pediatric restorative dentistry is preferential relative to other materials because of their fluoride release, chemical adhesion to tooth structure, and availability to use in a variety of clinical scenarios. This paper reviews the use of glass ionomer materials in pediatric restorative den...

Seven glass-ionomer cements were tested and compared with a composite resin in order to find the glass-ionomer cement with the highest bond strength to enamel with normal anatomy and composition (not ground). Five types of surface treatment were used. The results show that Aqua Cem and Ketac Cem, both water-hardening, present the highest bond strength, followed by the conventional glass-ionomer...

Previous studies indicated that toxic components can be released from glass ionomer cements and diffuse through dentinal tubules into the pulp. This in vitro study compared the cytotoxic effects produced to pulpal fibroblasts by the leachables of the primer systems and the diffusates through dentin of four resin-reinforced glass ionomer cements (Vitremer Tri Cure System, Dyract-Prime & Bond 2.0...

The aim of this study was to test the hypothesis that there is no difference in the fluoride release behavior of resin-reinforced glass ionomer cements before or after fluoride recharge. The materials were divided into 5 groups: 2 resin-reinforced glass ionomer cements used for attaching orthodontic bands, that is, group FOB (Fuji Ortho Band) and group MCB (Multi-Cure Glass Ionomer Orthodontic ...

This study compared the flexural strengths and bond strengths to dentin and enamel of two brands of silver-reinforced glass ionomers with their respective unfilled glass-ionomer cements for luting. The results led to the following conclusions. 1. No significant differences in bond strengths to tooth substrates were recorded between silver-reinforced and unfilled glass ionomers. 2. Although the ...

Glass ionomer cements (GICs) are widely used in restorative dentistry.1 In dentistry, one of their advantages over other restorative materials is that they can be placed into tooth cavities without an additional bonding agent.2 They also possess a fluoride-releasing property3 and are relatively biocompatible with the pulp.1 Adhesive property and fluoride release of glass ionomer cement contribu...

A variety of luting cements are available for use with orthodontic bands. This in vitro study was conducted to evaluate the force required to cause debanding when zinc phosphate, polycarboxylate and glass ionomer cements are used as the luting agents; and to determine whether sandblasting the inner surface of orthodontic bands affects the force required to deband. The data were obtained by deba...

General structure and properties Glass-ionomer cements were developed by Wilson and McLean at the Laboratory of the Government Chemist in England in 196527. They were a logical addition to the family of water-based dental cements, comprising silicate cement, zinc phosphate cement and zinc polycarboxylate cement. Since their commercial introduction, they are now available in essentially two type...

his article describes the properties, advances and shortcomings of glass-ionomer cement as a restorative material. The adhesion of glass-ionomer to tooth structure is less technique sensitive than composite resins and its quality increases with time. Therefore glass-ionomer might turn out to the more reliable restorative material in minimal invasive dentistry based on adhesive techniques. Unite...
