Surface Hardness of Resin Cement Polymerized under Different Ceramic Materials
Objectives. To evaluate the surface hardness of two light-cured resin cements polymerized under different ceramic discs. Methods. 40 experimental groups of 2 light-cured resin cement specimens (Variolink Veneer and NX3) were prepared and polymerized under 5 different ceramic discs (IPS e.max Press HT, LT, MO, HO, and Cercon) of 4 thicknesses (0.5, 1.0, 1.5, and 2.0 mm), Those directly activated...

متن کاملcomparative depth of cure among two light-cured core build-up composites by surface vickers hardness.
depth of cure of composite material is restricted and it depends on many parameters such as thickness. the aim of this in-vitro study was to evaluate the depth of cure of two light-cured core build-up composites (quixfil and photocore) in different thicknesses, when cured for 60 seconds.the vickers microhardness measurements were made for each side of the top irradiated surfaces of 1,2,3,4,5,6,...
متن کاملHardness of composite resin polymerized with different light-curing units
Introduction: The degree of polymerization depends on the type of light-curing unit. The aim of this study was to compare the hardness of composite resin cured by LED and Halogen light curing units. Methods: In this experimental study, 20 cylindrical samples of Tetric Ceram composite were prepared. Half of them were cured with Ultralume 2 LED and the other half with Astralis 7 Halogen light ...
متن کاملEffect of pre-heating on depth of cure and surface hardness of light-polymerized resin composites.
PURPOSE To evaluate the depth of cure and surface hardness of two resin composites when subjected to three preheating temperatures, three polymerization times and two types of curing lights. METHODS Two resin composites were used in this study (Esthet-X and TPH), three polymerization times (10, 20, 40 seconds), three preheating temperatures (70, 100, 140 degrees F/21.1, 37.7 and 60 degrees C)...
