Composite resins as a dental restorative material
Journal of Biomedical Materials Research, 1971AbstractThe 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, 1999Five 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, 2000ABSTRACT 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, 2016Adverse 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, 1992A 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.

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, 1999Resin 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.

Nanoparticle-reinforced resin-based dental composites
Journal of Dentistry, 2008TiO(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.

Post-curing in dental resin-based composites
Dental Materials, 2018To determine the post-curing in six commercial contemporary resin-based composites (RBCs) using axial shrinkage, the degree of conversion, and Vickers hardness.Five Bulk Fill and one conventional RBCs from three companies were selected with a wide range of filler volume content.

Hygroscopic expansion kinetics of dental resin-composites
Dental Materials, 2014To evaluate the extent and rate of hygroscopic expansion of resin composites at 37°C.Eight resin composites were examined: 1 micro-hybrid (Bright Light(®)), 5 nano-hybrids (Experimental Vertise™; Nanoceram-Bright(®); Tetric EvoCeram(®); Grandio(®) SO; Ceram X™ duo) and 2 flowables (X-tra base; Venus(®) Diamond Flow).
