the effect of bulk depth and irradiation time on the surface hardness and degree of cure of bulk-fill composites
statement of problem: for many years, application of the composite restoration with a thickness less than 2 mm for achieving the minimum polymerization contraction and stress has been accepted as a principle. but through the recent development in dental material a group of resin based composites (rbcs) called bulk fill is introduced whose producers claim the possibility of achieving a good rest...
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 کاملMicroleakage 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 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,...
