In vitro lingual bracket evaluation of indirect bonding with plasma arc, LED and halogen light
Authors - Magno AFF, Martins RP, Vaz LG, Martins LP Objectives - Evaluate the shear bond strength (SBS) and the adhesive remnant index (ARI) of indirect bonded lingual brackets using xenon plasma arc light, light-emitting ...
Shear bond strength of orthodontic brackets bonded using halogen light and light-emitting diode at different debond times
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. ...
Effect of light-curing method and indirect veneering materials on the Knoop hardness of a resin cement
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) ...
Effects of cement-curing mode and light-curing unit on the bond durability of ceramic cemented to dentin
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, ...
Temperature rise during adhesive and composite polymerization with different light-curing sources
AIM: This study evaluated the temperature rise of the adhesive system Single Bond (SB) and the composite resins Filtek Z350 flow (Z) and Filtek Supreme (S), when polymerized by light-emitting diode (LED XL 3000) and ...
Effect of thickness of indirect restoration and distance from the light-curing unit tip on the hardness of a dual-cured resin cement
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 ...
