Effect of resin matrix composition on the translucency of experimental dental composite resins

Dental Materials, 2009
The 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.

Functional fillers for dental resin composites

Acta Biomaterialia, 2021
Dental resin composites (DRCs) are popular materials to repair caries. Although various types of DRCs with different characteristics have been developed, restoration failures still exist. Bulk fracture and secondary caries have been considered as main causes for the failure of composites restoration.

Bioactive Dental Resin Composites with MgO Nanoparticles

ACS Biomaterials Science & Engineering, 2023
Photoactivating dental resin composites have been the most prevailing material for repairing dental defects in various clinical scenarios due to their multiple advantages. However, compared to other restorative materials, the surface of resin-based composites is more susceptible to plaque biofilm accumulation, which can lead to secondary caries and ...

Antibacterial dental resin composites

Reactive and Functional Polymers, 2014
Abstract Resin composite materials exhibit good esthetic properties and strength, making them the most commonly used materials for restoring hard tissue, i.e., enamel and dentin. In the last 30 years these restorative materials have been widely used for both anterior and posterior restorations.

Light transmission on dental resin composites

Dental Materials, 2008
The purposes of this study was: (1) to examine the light transmittance characteristics of two light-cured resin composites, for different thickness, (2) to correlate the light transmittance through the resin composites and the filler contents, and (3) to determine the penetration depth of the light as a function of the wavelength.Two resin composites ...

Fracture Behavior of Dental Composite Resins

Bio-Medical Materials and Engineering, 1991
Fracture toughness (KIC) critical stress intensity factor, and bending strength of 3 types of commercially available dental composite resins (macrofilled. hybrid and microfilled type) were determined using three point bend specimens. Acoustic Emission (AE), which is the generation of elastic wave due to the release of energy from the localized sources ...

Nanoparticle-reinforced resin-based dental composites

Journal of Dentistry, 2008
TiO(2) nanoparticles treated with the organosilane allyltriethoxysilane (ATES) are used to improve the mechanical properties of dental resin-based composites (RBCs, Z100, 3M ESPE).TiO(2) nanoparticles were sonically dispersed in an ethanol solution containing ATES. The modified particles were washed in pure ethanol and dried before being used as filler.

Nanomechanical properties of dental resin-composites

Dental Materials, 2012
To determine by nanoindentation the hardness and elastic modulus of resin-composites, including a series with systematically varied filler loading, plus other representative materials that fall into the categories of flowable, bulk-fill and conventional nano-hybrid types.Ten dental resin-composites: three flowable, three bulk-fill and four conventional

Repair of dental resin-based composites

Clinical Oral Investigations, 2012
The study analyzed the reparability and compatibility of light-curing resin-based composites (RBCs) of the categories "microhybrid," "nanohybrid," and "packable."Six RBCs with different matrix and filler formulation--purely methacrylate-based composites (MBCs), ormocer-based composites (OBCs), and silorane-based composites (SBCs)--were used for the ...

A composite resin bonded to dental materials

The Journal of Prosthetic Dentistry, 1981
Abstract Enamelite 500 will reattach a dislodged facing or orthodontic bracket and will serve as a veneer material over visible amalgam, gold, and nonprecious metals. Using this composite material as a veneer over metals and as a repair material can be a simple way to solve some esthetic problems.
