TLDR
The resin containing DMAEMA showed higher DC, shrinkage-strain,shrinkage-Strain rate, and microhardness, in addition to better optical properties, in Besides, color stability and transmittance were evaluated after different periods of artificial aging, according to ISO 7491:2000.About:

Progress in dimethacrylate-based dental composite technology and curing efficiency
TL;DR: A review of the key factors affecting the polymerization efficiency of light-activated resin-based composites highlights the apparent need for a more informative approach by manufacturers to relay appropriate information in order to optimize material properties of resin composites used in daily practice.

New polymer-chemical developments in clinical dental polymer materials: Enamel–dentin adhesives and restorative composites
Norbert Moszner,Thomas Hirt +1 more
TL;DR: New bisacrylamide cross-linkers with improved hydrolytic stability and new strongly acidic polymerizable phosphonic acids and dihydrogen phosphates, in combination with the implementation of novel application devices, have significantly improved the performance of the current enamel–dentin adhesives.

Degree of Conversion of a Resin Cement Light-Cured Through Ceramic Veneers of Different Thicknesses and Types
Patricio Runnacles,Gisele Maria Correr,Flares Baratto Filho,Carla Castiglia Gonzaga,Adilson Yoshio Furuse +4 more
TL;DR: The effect of different types and thicknesses of ceramic veneers on the degree of conversion of a light-cured resin-based cement (RelyX Veneer) depends on the thickness and type of ceramics employed when veneer thicker than 1.5 mm are cemented.

Correlation between hardness and degree of conversion during the setting reaction of unfilled dental restorative resins
TL;DR: Knoop hardness was correlated to degree of conversion (DC) of carbon double bonds, determined by IR, during the setting reaction of three unfilled dental resins, indicating increase in hardness correlates well with increases in DC during setting.

Color stability of dental composite resin materials for crown and bridge veneers
I.E. Ruyter,K. Nilner,B. Möller +2 more
TL;DR: The color stability of 3 light-polymerized veneer materials were investigated and compared to that of 3 conventional heat- and auto-polymers materials and the accelerated test had the ability to discriminate between the various products.

Light intensity effects on resin-composite degree of conversion and shrinkage strain.
TL;DR: The correlation between DC and shrinkage strain values means that some reductions in the problems of shrinkage may be achieved by an acceptable reduction in DC, however, this must also be consistent with generating adequate curing performance in the resin-network.

The Effects of Light Intensity, Temperature, and Comonomer Composition on the Polymerization Behavior of Dimethacrylate Dental Resins
TL;DR: It is concluded that the BisGMA portion of the mixture largely controls the polymerization mechanisms and kinetics, which suggests that TEGDMA is an excellent diluent, since it increases the mobility of the reacting medium; however, the high reactivity is due to the presence of BisGma.

Filler features and their effects on wear and degree of conversion of particulate dental resin composites.
TL;DR: Filler size and geometry was found to have a significant effect on wear resistance and DC of composites, without compromising the percentage of reacted carbon double bonds at specific sizes and combinations.
