Influence of Light-Curing Intensity on Color Stability and Microhardness of Composite Resins.
The international journal of periodontics & restorative dentistry, 2020The purpose of this study was to evaluate the intensity of light-curing units and its relationship with the color stability and microhardness of composite resins with different shades subjected to a thermocycling procedure.

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

OBJECTIVES The objective of this in vitro study was to compare, with a threshold value of 200 nm, the surface roughness obtained when using 12 different polishing systems on four different composite resins (microfill, nanofill, and two nanohybrids ...

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.

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.
