Biomaterials, 1995
Porosity in the pastes of composite resins before and after polymerization has been measured. The influence of the diameter of the extrusion orifices and the spatulation of the chemically-activated pastes has been evaluated. Considering that thin layers of these materials are transparent, the investigation has been carried out mainly by analysis of ...

Dental Clinics of North America, 1985
The interest in posterior composite resins has grown rapidly during the last several years. Much of the interest has been initiated by a demand for esthetic dentistry. Some has developed as a result of a concern by some for mercury sensitivity. Despite their growing popularity, a number of major problems persist. Some of these deal with the restorative

Effect of resin matrix composition on the translucency of experimental dental composite resins
Dental Materials, 2009The purpose of this study was to investigate the effect of the resin matrix composition on the translucency of experimental dental composite resins.Three types of unfilled resin matrices (TEGDMA-, UDMA- and BisGMA-based) were formulated and light cured.

A quarter of a century ago, composite resin was introduced and quickly outmoded silicate cement and acrylic resin as a restorative material. Although composite resin cannot replace amalgam, it has a strong foothold in dentistry, most notably for its superior color-matching ability.

Composite resins are polymer-based materials used in dentistry for aesthetic repairs. They are prepared by free radical polymerization, which in modern materials is visible-light initiated. Monomers are bulky, viscous substances that react to create an organic matrix that is tough and durable in clinical service.

Optical properties of composite resins
Journal of Oral Rehabilitation, 1982SummaryThe translucency and colour of a composite resin are characterized by two wavelengthdependent parameters: the absorption coefficient, K and the scattering coefficient, S. These parameters were calculated according to the Kubelka‐Munk (1931) equations for two commercial resins.

Measurement of opalescence of resin composites
Dental Materials, 2005Opalescence is an optical property, where there is light scattering of the shorter wavelengths of the visible spectrum, giving the material a bluish appearance under reflected light and an orange/brown appearance under transmitted light. The objective of this study was to determine the opalescence of resin composites with a color measuring ...

Composite Resin in Medicine and Dentistry
Journal of Long-Term Effects of Medical Implants, 2005Composite resin has been used for nearly 50 years as a restorative material in dentistry. Use of this material has recently increased as a result of consumer demands for esthetic restorations, coupled with the public's concern with mercury-containing dental amalgam.

An Abrasion Test for Composite Resins
Journal of Dental Research, 1980An abrasive wear test for composite resins was proposed. A slurry of glass pearls and abrasive particles were used. The abrasive effect was examined for different particle sizes. Particle sizes were found which gave the same order of wear as found clinically for an amalgam, a composite resin, and unfilled resin.
