Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
(2009-06-01)
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) ...

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 ...
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 ...

The effects of exposure time on the surface microhardness of three dual-cured dental resin cements
(2011-09-01)
This study evaluated the exposure time of light-curing of the polymers used for cementation on microhardness test in different storage times. The polymers (specifically called resin cements) were RelyX ARC, RelyX U100, and ...
