Abstract
This study evaluates a bulk fill resin composite by comparing it with a conventional build up one, using two different curing lights, regarding; Degree of Conversion (DC), microleakage, micro hardness and fracture toughness. Two nanohybrid resin composites were investigated; Tetric N-Ceram Bulk Fill and Tetric N-Ceram. Specimens of each type were divided into two equal groups: Group A cured with Quartz Tungsten Halogen (QTH) and Group B cured with light-emitting diode (LED). DC, microleakage, micro hardness and fracture toughness of different groups were studied. The Chi-Square test and t-test were then used to analyze and compare the results statistically. Results show that, there were no signifi cant diff erences among the materials tested and additionally, none of the used curing lights had a more prominent effect on the properties of the tested composites.
