Influence of different light-curing units in surface roughness and gloss of resin composites for bleached teeth after challenges
(2020-02-01)
The aim of this study evaluates the surface roughness and gloss of resin composites for bleached teeth, using different modes of light curing and photoinitiators after challenges. Eighty discs were made with Filtek Z350XT ...
The influence of a translucent fiberglass post on the polymerization of dual cure resin cement analyzed by electron paramagnetic resonance
(2015-01-01)
Electron Paramagnetic Resonance (EPR) was used as an alternative method to study the conversion degree of dual cure resin cement and verify the influence of prefabricated translucent fiberglass post on the dual cure resin ...
Effect of light-curing method and indirect veneering materials on the Knoop hardness of a resin cement
(2009-12-08)
This study evaluated the Knoop hardness of a dual-cured resin cement (Rely-X ARC) activated solely by chemical reaction (control group) or by chemical / physical mode, light-cured through a 1.5 mm thick ceramic (HeraCeram) ...
Influence of Light-Curing Intensity on Color Stability and Microhardness of Composite Resins
(Quintessence Publishing Co Inc, 2020-01-01)
The purpose of this study was to evaluate the intensity of light-curing units and its relationship with the color stability and microhardness of composite resins with different shades subjected to a thermocycling procedure. ...
Knoop hardness of dental resin cements: Effect of veneering material and light curing methods
(Elsevier B.V., 2007-04-01)
This study evaluated the Knoop hardness of one resin cement (dual-cure mode or light-cure mode) when illuminated directly or through restorative materials-ceramic (HeraCeram) or composite (Artglass)-by two light curing ...
Shrinkage stress and temperature variation in resin composites cured via different photoactivation methods: Insights for standardisation of the photopolymerisation
(2021-07-01)
The literature has shown that there is no consensus regarding the best resin composite photoactivation protocol. This study evaluated the efficiency of the conventional, soft-start, pulse-delay and exponential protocols ...
Effects of cement-curing mode and light-curing unit on the bond durability of ceramic cemented to dentin
(2013-03-01)
The aim of this study was to evaluate the effects of different light-curing units and resin cement curing types on the bond durability of a feldspathic ceramic bonded to dentin. The crowns of 40 human molars were sectioned, ...
