A model of the viscoelastic behavior of flowable resin composites prior to setting

Genotoxic potential of dental bulk-fill resin composites

“…While their physico-mechanical properties, handling characteristics and wear performance have been extensively tested [34][35][36][37][38][39], scientific data on the biocompatibility of bulk-fill composite materials are very scarce [22]. The present study is the first that investigated potential genotoxic effects emanating from resin-based bulk-fill materials.…”

Mechanical properties, shrinkage stress, cuspal strain and fracture resistance of molars restored with bulk-fill composites and incremental filling technique

“…Resin composites have been extensively employed in restorative dentistry for several decades [1]. More than five hundred millions direct dental restorations are placed every year around the world which representes one of the most prevalent medical interventions in the human body [2].…”

Rheological approach for determining yield stresses in flowable resin composites prior to setting

“…Unlike previous rheological studies, in which the fluidity of flowable resin composites was evaluated according to viscosities under low shear conditions 7,22) , we evaluated fluidity using yield stress (defined as shear stress at a shear rate of zero) approximations from shear stresses at low shear rates of 0.2-1.0 s −1 . Because the shear rate of 0.2 s −1 is close to the lower limits of common viscometers, flow curves of shear stress versus shear rate (Fig.…”
