A bulk-fill technique
Direct composites in posterior teeth are a part of the standard therapy spectrum in modern dentistry. The excellent performance of this form of restoration in the masticatory load-bearing posterior region has now been demonstrated in numerous clinical studies. The procedure is usually carried out in an elaborate layering technique. Aside from the possibilities that highly aesthetic composites o...
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 کاملColor Stability of Two Bulk-Fill Composite Resins
Objective: Bulk-fill composites are a group of composite resins designed for easy and fast filling of large cavities. This study aimed to assess the color stability of bulk-fill composites subjected to xenon radiation and evaluate their color change (&DeltaE) following polymerization. Methods: In this in vitro experimental study, 30 specimens (4mm in height and 8mm in diameter) were fabricat...
متن کاملMicrohardness of Bulk-Fill Composite Materials
The aim of the study was to determine microhardness of high- and low-viscosity bulk-fill composite resins and compare it with conventional composite materials. Four materials of high-viscosity were tested, including three bulk-fills: QuiXfi l (QF), x-tra fi l (XTF) and Tetric EvoCeram Bulk Fill (TEBCF), while nanohybrid composite GrandioSO (GSO) served as control. The other four were low-viscos...
متن کاملA laboratory evaluation of bulk-fill versus traditional multi-increment-fill resin-based composites.
Some concerns exist, however, regarding bulk-fill composites. One proposed rationale for limiting composite increments to 2 mm is to allow the curing light to penetrate to the resin farthest away from the light source.1,2 A second reason for using 2-mm increments is to minimize the shrinkage and shrinkageinduced stress associated with composite polymerization. Contraction stresses that exceed t...
