The ultrastructure of a dental composite resin

Proceedings, annual meeting, Electron Microscopy Society of America, 1988
Methacrylate has been used as a resin with exceptional cutting quality for electron microscopy, but suffers from problems of stability in the electron beam. On the other hand, one of the areas it is used is as a synthetic resin where it is increasingly becoming a factor in the restoration of missing tooth structure in dentistry.

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.

Composite resins as a dental restorative material

Journal of Biomedical Materials Research, 1971
AbstractThe objective of this study was to assess the finished surfaces of various dental composite resin restorative materials using common rotating abrasive devices and diamond and iron‐carbide dental burs. The “finished” surfaces were compared with surfaces created by a polyester matrix band.

HPLC Analysis of Dental Resin Composites Components

Journal of Biomedical Materials Research Part B, 1999
Five uncured commercial dental resin composites (two bis-glycidyl methacrylate based products and three non-bis-glycidyl methacrylate based products) were examined for contamination with bisphenol A, which is a known xenobiotic. After the samples were processed with acetonitrile for extraction of their components, high performance liquid chromatography

Curing Dental Resins and Composites by Photopolymerization

Journal of Esthetic and Restorative Dentistry, 2000
ABSTRACT The development and continued evolution of photopolymerizable dental materials, particularly dental composite restoratives, represent a significant, practical advance for dentistry. The highly successful integration of the light‐activated curing process for dental applications is described in this review. The basic mechanisms

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.

Initiation of Polymerization with Ultrasound in Dental Composite Resin

Biomaterials, Artificial Cells and Immobilization Biotechnology, 1992
A single paste composite resin comprising methacrylate monomers, inorganic fillers, activators and an ultrasonic generator assembled by a piezoceramic transducer and a working tip was developed. The resin can polymerize and harden under irradiation with ultrasound having frequencies from 20 to 50 KHz and intensity from 12 to 40 W/cm2.

Dental Composite Resins

2012
Abstract This article discusses the composition of the major components of dental composite resins: organic resin matrix, filler, coupling agents, and initiator-accelerator systems. It describes the properties of composite resins that are related to the amount and type of filler and resin-matrix compositions.

Ceramic Whisker Reinforcement of Dental Resin Composites

Journal of Dental Research, 1999
Resin composites currently available are not suitable for use as large stress-bearing posterior restorations involving cusps due to their tendencies toward excessive fracture and wear. The glass fillers in composites provide only limited reinforcement because of the brittleness and low strength of glass.
