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

The Journal of the American Dental Association, 1988
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.

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.

Novel glassflake resin composites
Dental Materials, 2016Purpose: Glassflakes (GFs) are high aspect ratio glass platelets that are widely used in anti-corrosion coatings for the oil industry due to the unique layering characteristic (overlap and align parallel to substrate surfaces as a corrosive barrier).

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 ...

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.

The evaluation of resin composite consistency
Dental Materials, 1998To evaluate a method for the assessment of the consistency of unset resin composite.Fourteen commercial resin composites were selected, which had a range of consistencies as assessed subjectively. The material was placed in a cylindrical mold with 8 mm diameter and 8 mm depth, and a glass rod with 4.37 mm diameter driven into the composite at 24.4 mm ...

The composite resin post and core
The Journal of Prosthetic Dentistry, 1972Abstract It is not the purpose of this article to advocate that the composite resin post and core is superior to the cast dowel and coping or pin-retained amalgam. However, it is a technique which is both economical and time saving. Clinical experience and judgment must provide the final standard for its application.

Porosity in posterior composite resins
European Journal of Oral Sciences, 1986Abstract – The percent pore area and the mean pore size were measured in specimens made of nine brands of composite resin restorative materials. The overall percent porosity ranged from 0.01 to 4.5%. The specimens for the study were prepared in two ways; by condensation or by pressure.
