To determine degree of conversion (DC), maximum polymerization rate (RPmax), shrinkage (PS), (PS Rmax) and fracture toughness (KIC) different types bulk-fill (BF) composites plus the effect viscosity reduction techniques. BF specimens were created in 2 mm deep molds: SonicFill 3 (SF3), Viscalor (VC), One Bulk Fill (OBF) Beautifil (BBR). SF3 was applied via sonic insertion using a handpiece (Ker...

Purpose: The objective of this study was to evaluate the physical and mechanical properties a short fiber-reinforced resin composite: everX-Posterior compare it with two bulk-fill composites, namely, Filtek Bulk-fill Beautifil-Bulk, which are intended for large posterior restorations.

Aim Comparative evaluation of the fracture resistance of maxillary premolar teeth restored with two high-viscosity bulk-fill composites and incrementally placed composite. Materials and Methods Seventy-five freshly extracted maxillary premolar teeth were selected. Fifteen specimens served as positive control (Group 1). Mesio-occluso-distal cavity preparation was prepared on the rest of the sp...
