Microleakage of Bulk-Fill Composites at Two Different Time Points
Objectives: Microleakage is the main concern in composite restorations. This study aimed to compare the microleakage of two bulk-fill and one conventional composite at two different time points. Methods: Class II cavities were prepared in 60 premolar teeth and divided into six groups of 20. Groups 1 and 4 were incrementally filled with Grandio composite. Groups 2 and 5 were filled with X-tra...
متن کاملPolymerization shrinkage stress of composites photoactivated by different light sources.
The purpose of this study was to compare the polymerization shrinkage stress of composite resins (microfilled, microhybrid and hybrid) photoactivated by quartz-tungsten halogen light (QTH) and light-emitting diode (LED). Glass rods (5.0 mm x 5.0 cm) were fabricated and had one of the surfaces air-abraded with aluminum oxide and coated with a layer of an adhesive system, which was photoactivated...
متن کاملComparing the Microleakage of Bulk-Fill (flowable, packable) Composite Restorations and Conventional Light-cured Composites
Introduction and aim: Bulk Fill composites have increased polymerization depth and their contraction stress, and cuspal deflection are reduced in comparison with conventional composites. Therefore, it is claimed that their microleakage is reduced. The aim of this study was to compare microleakage of (flowable and packable) Bulk Fill and conventional resin composites. Materials and Methods: Thi...

متن کاملOptical and Surface Properties of Different Bulk - Fill Resin Composites after Storage in Different Media
Aim: to evaluate and compare surface properties (wettability, surface roughness and color) of paste bulk fill resin composite materials on baseline and after incubation in RedBull or Black coffee storage media and to find out if there is any change in these surface properties after 1 week and 1 month incubation. Materials and Methods: Three bulk-fill resin composites (Filtek bulk fill3M, X-traf...
