Effect of curing protocol on the polymerization of dual-cured resin cements
(ELSEVIER SCI LTD, 2010)
Objectives. The purpose of this study was to evaluate how curing protocol affects the extent of polymerization of dual-cured resin cements. Methods. Four commercial resin cements were used (DuoLink, Panavia F 2.0, Variolink ...
Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
The aim of this study was to evaluate the hardness of a dental composite resin submitted to temperature changes before photo-activation with two light-curing unite (LCUs). Five samples (4 mm in diameter and 2 mm in thickness) ...
Viscosity, pH, and moisture effect in the porosity of poly(furfuryl alcohol)
The poly(furfuryl alcohol) is highly indicated to obtain advanced carbonaceous materials due mainly to its good carbon yield (around 50%) and a controllable cure reaction. In the processing of some carbonaceous materials, ...

The effect of curing light and chemical catalyst on the degree of conversion of two dual cured resin luting cements
(SPRINGER LONDON LTDLONDON, 2012)
The aim of this study was to evaluate the influence of different curing lights and chemical catalysts on the degree of conversion of resin luting cements. A total of 60 disk-shaped specimens of RelyX ARC or Panavia F of ...
Effect of pre-heating resin composite and light-curing units on monomer conversion
The purpose of this study was to evaluate the effect of pre-heating resin composite photo-cured with light-curing units (LCU) by FT-IR. Twenty specimens were made in a metallic mold (4 mm diameter × 2 mm thick) from composite ...
Influence of curing tip distance on resin composite Knoop Hardness Number, using three different light curing units

Dielectric thermal analysis as a tool for quantitative-evaluation of the viscosity and the kinetics of epoxy resin cure
(Institute of Electrical and Electronics Engineers (IEEE), 2006-06-01)
Dielectric thermal analysis has been proved as a valuable tool for monitoring the epoxy curing process and the related rheological properties in the fabrication of polymer-matrix composite materials. This technique also ...
Curing depth of composite resin light cured by LED and halogen light-curing units
(Maik Nauka/interperiodica/springer, 2008-11-01)
The purpose of this study was to evaluate the polymerization effectiveness of a composite resin (Z-250) utilizing microhardness testing. In total, 80 samples with thicknesses of 2 and 4 mm were made, which were photoactivated ...
