Correlation between light intensity and exposure time on the hardness of composite resin
(SpringerDordrechtHolanda, 2000)
Shear bond strength of orthodontic brackets bonded using halogen light and light-emitting diode at different debond times
(2010-01-01)
The aim of this in vitro study was to compare the photoactivation effects of QTH (Quartz-Tungsten-Halogen) and LED (Light-Emitting Diode) on the SBS (Shear Bond Strength) of orthodontic brackets at different debond times. ...
Influence of curing protocol on selected properties of light-curing polymers: Degree of conversion, volume contraction, elastic modulus, and glass transition temperature
(ELSEVIER SCI LTD, 2009)
Objectives. The purpose of this study was to investigate the effect of light-curing protocol on degree of conversion (DC), volume contraction (C), elastic modulus (E), and glass transition temperature (T(g)) as measured ...
Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2009)
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) ...
Monomer conversion at different dental composite depths using six light-curing methods
(Elsevier Sci LtdOxfordInglaterra, 2006)
Effects of curing protocol and storage time on the micro-hardness of resin cements used to lute fiber-reinforced resin posts
(UNIV SAO PAULO FAC ODONTOLOGIA BAURUBAURU-SP, 2012)
Objectives: To determine the micro-hardness profile of two dual cure resin cements (RelyX - U100 (R), 3M-ESPE and Panavia F 2.0 (R), Kuraray) used for cementing fiber-reinforced resin posts (Fibrekor (R) - Jeneric Pentron) ...
Hardening of a dual-cure resin cement using QTH and LED curing units
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2010-03-01)
Objective: This study evaluated the surface hardness of a resin cement (RelyX ARC) photoactivated through indirect composite resin (Cristobal) disks of different thicknesses using either a light- emitting diode (LED) or ...
