Objectives The uptake of F − ions by glass ionomer cement (GIC) has been extensively studied but the precise location of the F − ion in the GIC structure has not been reported. The aim of this study is to use model materials to elucidate the poss

It was thought that when finishing and polishing direct filling materials lubrication would affect the surface roughness and temperature rise in samples of amalgam and composite. Object Previous work by the authors has shown that there is an optimum

Object Previous work [Jones CS. Factors influencing the finishing of direct filling materials. PhD Thesis, University of London; 2002] has shown that there is an optimum load, speed and time that produced the smoothest surface when finishing glass-io

Lasers have been used for hard tissue cutting in dentistry for a number of years. The quality of the cavity preparation and the surface finish achievable is variable and is dependant on operating wavelength. The collateral damage, which may be produc

Group interaction modeling (GIM) is used to predict the changes in the volume and, therefore, shrinkage of a wide variety of commonly encountered acrylate and methacrylate monomers during polymerization. The predictions of the model are in excellent

The strength of a modern, low metal:glass ratio, metal-reinforced glass-ionomer cement was measured evaluating a number of protective barriers: one light-cured resin, two solvent-based dental varnishes and petroleum jelly. The cement was exposed to w

The cariostatic action of the glass-ionomer cement has been attributed to its sustained release of fluoride. The fluoride in the set cement originates from the glass particles which are eroded, in part, during the setting reaction. In this study a wa
