In addition to being structural materials, polymers also make a signifi cant contribution to cements and adhesives. This entry reviews three adhesive mechanisms, all of which utilize polymers, and are widely applicable in contemporary dental practice

To enable further work to be carried out on the hydration of hemihydrate plasters, materials purer than the available commercial plasters and with reproducible properties were required. As a first stage in the attempted preparation of such materials,

The properties of one batch of autoclave calcium sulphate hemihydrate have been determined. A study has been made of the effects of various concentrations of acetic acid, and potassium and calcium acetates on (i) the rate of evolution of heat, (ii) t

The kinetics of the hydration of two sources of autoclaved calcium sulphate hemihydrate have been followed by an essentially isothermal method. Experiments have been carried out at different temperatures, water/powder ratios, and with added nuclei of

Tooth bleaching materials need to flow easily on insertion but should have high viscosity at low stresses to stay in place on the teeth. Some degree of elasticity may also aid retention on the teeth thereby maximizing efficacy. The present work was u

Coatings of tin oxide have been deposited onto alumina using both physical vapour deposition (PVD) and chemical vapour deposition (CVD) techniques. Significant increases in bond strength were determined for certain of the PVD groups of samples. The P

Alumina reinforced dental porcelain has been coated directly with tin oxide by reactive ion plating. Samples were prepared at different distances from the tin source in the ion plating rig. Tensile bond strengths of treated and untreated porcelain di

There is current concern about bacterial contamination of dental unit waterlines. This research hypothesized that the presence of increasing concentrations of bacteria in water used to wash etched enamel would result in a corresponding decrease in bo

This pilot study was undertaken to determine the compositional changes in tooth bleaching materials as a function of time in vivo. Ten patients were recruited and two bleaching systems were used - one a paste and the other a gel. Each material was pl

Many methodologies are used during the testing of dental materials. Among these are compressive, tensile and flexural strengths, and fracture toughness. However, different tests are relevant to different materials and clinical situations. This paper
