Fluoride release from dental resin composites

Materials Science and Engineering: C, 2005
The fluoride release from dental composites has reported as an important factor in the inhibition of dental caries. The aim of this study was to determine the amount of fluoride release from two resin composites with different powder/liquid ratio. The experimental resin composites consisted of a resin system and inorganic filler based on quartz and ...

Polymerization of dental composite resins using plasma light

Biomaterials, 2002
Five visible light-cured composite resins used as restoration or adhesive materials in dentistry, were irradiated with high energy plasma light (1300 mW/cm2), and contraction, rate of contraction, irradiation-induced temperature were analysed. A comparison was carried out with the same materials irradiated with a conventional halogen light (400 mW/cm2).

Optical characteristics of contemporary dental composite resin materials

Journal of Dentistry, 2013
Optical and physical properties of dental restorative composite materials are affected by composition. Basic optical absorption and scattering properties have been derived through the use of a corrected reflectance model, but practical and important optical properties are not easily derived from these basic spectral characteristics.

Composition of Dental Resin-Based Composites for Direct Restorations

2017
Ever since the introduction of light-curable resin-based composites in the 1970s, these mixtures of organic and inorganic phases have continuously evolved to meet the increasing requirements of material design and dental practitioners. However, fundamentally, the chemistry of composite phases has not significantly changed, with material design that ...

Hypersensitivity to dental composites and resin-bonding agents

Dental Update, 2016
Adverse reactions to dental materials are not an uncommon occurrence, although hypersensitivity has gained much renewed interest in light of public concerns over the safety of dental materials. Hypersensitivity can affect both patients and dental professionals and may manifest as either allergic contact dermatitis or stomatitis.

Dynamic visco-elastic properties of dental composite resins

Dental Materials, 2006
This study aimed to examine the visco-elastic properties of dental composites by dynamic mechanical analysis under the influence of clinically relevant temperatures and variable frequencies, after being stored in air or distilled water for up to 3 months.Two direct (Diamond Lite and Grandio) and two indirect (Artglass and Vita Zeta LC) composites were ...

Diffusion coefficient of water through dental composite resin

Biomaterials, 2003
Water sorption of polymer filling materials affects dimensional stability, mechanical properties and bonding strength with tooth structures. To clarify the effect of the degradation on service life and micro-leakage, the diffusion coefficient of water through the resin should be identified.

Interpenetrating network ceramic-resin composite dental restorative materials

Dental Materials, 2016
This paper investigates the structure and some properties of resin infiltrated ceramic network structure materials suitable for CAD/CAM dental restorative applications.Initially the basis of interpenetrating network materials is defined along with placing them into a materials science perspective.

Flexural fatigue behavior of resin composite dental restoratives

Dental Materials, 2003
The aim of this study was to evaluate the mechanical properties of resin composite dental restoratives under quasi-static and cyclic loading.Four-point-bending bars of 10 different resin composite materials were manufactured according to ISO standard and stored for two weeks in distilled water.

Resin Based Dental Composites — An Overview

1986
The quest for a durable, esthetic, adhesive and biocompatible material with both good handling and setting qualities suitable for the restoration of lost or damaged tooth structure has long challenged dental material researchers. A significant step toward the realization of this goal was the development of resin based dental composites which overcame ...
