OBJECTIVES The aim of this study was to evaluate the effects of different light sources and curing time on the degree of conversion and microhardness of two surfaces within a nanofilled composite resin. METHODS Four experimental groups (n=10) were formed in accordance with the light source (quartz-tungsten halogen (QTH - 600mW/cm(2)), or light-emitting-diode (LED - 800mW/cm(2))) and the time ...
BACKGROUND The aim of this study was to investigate the effect of different concentrations of 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) monomer in one-step self-etch experimental adhesives on dentinal microshear bond strength (µSBS), their degree of conversion and bonded micro structure. MATERIAL AND METHODS Composite resin cylinders (Clearfil AP-X) were bonded on human sound mola...
This study investigated the physicochemical properties of the new formulation of the glass ionomer cements through hardness test and degree of conversion by infrared spectroscopy (FTIR). Forty specimens (n = 40) were made in a metallic mold (4 mm diameter x 2 mm thickness) with two resin-modified glass ionomer cements, Vitrebond™ and Vitrebond™ Plus (3M/ ESPE). Each specimen was light cured wit...
Background: There are still controversies in the literature as to which is best resinous cementing agent. Due this fact and immense availability of types brands agents, further studies needed evaluate properties these important dental materials. Objective: To assess degree monomer conversion (DC) Knoop microhardness (KHN) four resin cements: two conventional dual-cured cements (EnForce RelyXARC...
