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.

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

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.

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.

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.

Wear Rates of Resin Composites
Operative Dentistry, 2013SUMMARY A laboratory study was conducted to examine the wear of resin composite materials using a generalized wear simulation model. Ten specimens each of five resin composites (Esthet•X [EX], Filtek Supreme Plus [SP], Filtek Z250 [Z2], Tetric EvoCeram [EC], and Z100 Restorative [Z1]) were subjected to wear challenges of 100,000, 400,000,

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 ...
