Under clinical conditions, conventional glass-ionomer dental cements can be cured by application of heat from dental cure lamps, which causes acceleration in the setting. In order for this to be successful, such heat must be able to spread sufficiently through the cement to enhance cure, but not transmit heat so effectively that the underlying dental pulp of the tooth is damaged. The current st...

Glass ionomer based materials are clinically popular in several areas of restorative dentistry, but restoration of cervical lesions has proven particularly successful. Various etiologies, conformations, locations and structural characteristics make non-carious cervical lesions more challenging to adhesive restorative procedures and marginal seal in the long run. Due to their characteristics, gl...

Glass ionomer cements (GICs) are dental materials that were invented by Wilson & Kent in 1972. They can chemically bond to enamel and dentin exhibit anti-cariogenic activity allows the release uptake of fluoride ions. also possess ability render color. The setting reaction GICs is a neutralization results formation polycarboxylate salts. most important GIC modification process involves addi...

Since luting cement is used for fixing cast restorations to their abutments, the cement surface at the junction between cast and tooth is exposed to oral environment. The conventional cement so far used does not adhere to the tooth and is slightly soluble into saliva and gingival fluid1,2). Consequently, the microleakage and subsequent recurrent caries seem to develop at this junction. Recently...

This study investigated the effects of spherical silica filler (SSF) on the workability and mechanical properties of resin-modified glass ionomer cements for luting (RMGICL). Varying powder/liquid ratios (P/L=2.0, 2.2, 2.4, and 2.6) of a commercially available glass ionomer cement (Fuji Lute, GC Corp.) were mixed with SSF at different weight percentages (5, 7.5, and 10%). On film thickness, sta...

background: with regard to potential retrievability of cement-retained implant restorations, the retentive strength of the luting agents is critical. the aim of this study was to evaluate the retention values of implant-supported metal copings using different luting agents. materials and methods: twenty iti implant analogs and solid abutments of 5.5-mm height were embedded vertically in autopol...

Introduction A great number of techniques have been used for bonding orthodontic brackets to the tooth surfaces. Glass ionomer cements are frequently used material for this purpose. The aim of this study was to measure the shear bond strength of orthodontic brackets bonded with glass ionomer cement Ortho Fuji LC and remained adhesive on the enamel surface after brackets debonding. Material and ...
