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) ...

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 ...
Effect of pre-heating resin composite and light-curing units on monomer conversion
(2010-01-01)
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 ...

Effect of thickness of indirect restoration and distance from the light-curing unit tip on the hardness of a dual-cured resin cement
(2010-08-20)
This study evaluated the Knoop hardness and polymerization depth of a dual-cured resin cement, light-activated at different distances through different thicknesses of composite resin. One bovine incisor was embedded in ...

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 ...
