Glass ionomer cements based in TiO2 by Sol-gel method

Glass ionomer cements.

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...

Do conventional glass ionomer cements release more fluoride than resin-modified glass ionomer cements?

OBJECTIVES The aim of this study was to evaluate the fluoride release of conventional glass ionomer cements (GICs) and resin-modified GICs. MATERIALS AND METHODS The cements were grouped as follows: G1 (Vidrion R, SS White), G2 (Vitro Fil, DFL), G3 (Vitro Molar, DFL), G4 (Bioglass R, Biodinâmica), and G5 (Ketac Fil, 3M ESPE), as conventional GICs, and G6 (Vitremer, 3M ESPE), G7 (Vitro Fil LC,...

Clinical performance of glass-ionomer cements

Glass-ionomer cements were developed by Wilson and McLean at the Laboratory of the Government Chemist in England in 1965. 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 types. ‘Conventional’ glass-ionomers co...

Glass-ionomer Cements, the Interesting Alternative for Resin-based Composites

Fluoride Release by Glass Ionomer Cements, Compomer and Giomer

BACKGROUND To measure the amounts of fluoride released from fluoride-containing materials, four glass ionomer cements (Fuji IX, Fuji VII, Fuji IX Extra and Fuji II LC), a compomer (Dyract Extra) and a giomer (Beautifil) were used in this study. METHODS Twenty cylindrical specimens were prepared from each material. The amount of released fluoride was measured during the first week and on the d...
