Optical characteristics of experimental dental composite resin materials

Journal of Dentistry, 2022
To derive the K-M optical coefficients of experimental composites and compare the inherent CIE L*, a* and b* color parameters, translucency parameters and both perceptibility and acceptability thresholds.Experimental composites were prepared with 4 base-monomers: Bis-GMA, UDMA, Bis-EMA and Fit852 with TEGDMA used as a co-monomer and 3 filler:resin ...

Hygroscopic expansion kinetics of dental resin-composites

Dental Materials, 2014
To 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).

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.

Post-curing in dental resin-based composites

Dental Materials, 2018
To 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.

HPLC analysis of dental resin composites components

Journal of Biomedical Materials Research, 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

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.

Curing Dental Resins and Composites by Photopolymerization

Journal of Esthetic and Restorative Dentistry, 2000
ABSTRACTThe 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.

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.
