Influence of Energy Density of Different Light Sources on Knoop Hardness of a Dual-cured Resin Cement
The purpose of this study was to evaluate the Knoop hardness of a dual-cured resin-based luting cement irradiated with different light sources as well energy density through a ceramic sample. Three light-curing unit (LCUs) were tested: tungsten halogen light (HAL), light-emitting diode (LED) and xenon plasma-arc (PAC) lamp. Disc-shaped specimens were fabricated from a resin-based cement (Enforc...
متن کاملEffect of light-curing units, post-cured time and shade of resin cement on knoop hardness.
The aim of this study was to evaluate the Knoop hardness after 15 min and 24 h of different shades of a dual-cured resin-based cement after indirect photoactivation (ceramic restoration) with 2 light-curing units (LCUs). The resin cement Variolink II (Ivoclar Vivadent) shade XL, A2, A3 and opaque were mixed with the catalyst paste and inserted into a black Teflon mold (5 mm diameter x 1 mm high...
متن کاملeffect of light intensity on the degree of conversion of dual-cured resin cement at different depths with the use of translucent fiber posts.
to evaluate the effect of different light intensities on the degree of conversion (dc) of dual-cured resin cement at different depths of translucent fiber posts.thirty translucent fiber posts were randomly assigned into three (n=10) groups. they were cemented in the simulated canal spaces using duo-link dual-cured resin cement. the cement was light-cured under 600, 800 and 1100 mw/cm(2) light i...
متن کاملDegree of conversion of two dual-cured resin cements light-irradiated through zirconia ceramic disks
PURPOSE The aim of this Fourier transform infrared (FTIR) spectroscopic study was to measure the degree of conversion (DC) of dual-cured resin cements light-irradiated through zirconia ceramic disks with different thicknesses using various light-curing methods. MATERIALS AND METHODS Zirconia ceramic disks (KT12) with three different thicknesses (1.0, 2.0, and 4.0 mm) were prepared. The light ...

OBJECTIVES To evaluate the effect of different light intensities on the degree of conversion (DC) of dual-cured resin cement at different depths of translucent fiber posts. MATERIALS AND METHODS Thirty translucent fiber posts were randomly assigned into three (n=10) groups. They were cemented in the simulated canal spaces using Duo-Link dual-cured resin cement. The cement was light-cured unde...
