The purpose of this study was to examine the characteristics of an innovative composite material for dental restorations based on silorane--a monomer with a new chemical composition, and thereby compare the examined characteristics against those of well-known methacrylate-based composites. Degree of conversion at 2-mm and 6-mm depths as well as hardness, modulus of elasticity, and creep resista...

The aim of this study was to evaluate the radiopacity of silorane and methacrylate resin composites, comparing them to the enamel, dentin, and aluminum penetrometer using a digital image. From six resin composites (Filtek™ P90, Filtek Z350, Filtek Z350 XT flow, Tetric Ceram, TPH Spectrum, and SureFil SDR flow) cylindrical disks (5 × 1 mm) were made and radiographed by a digital method, together...

The aim of this study was to evaluate the tissue compatibility of a silorane-based resin system (Filtek™ Silorane) and a methacrylate-based nanoparticle resin (Filtek™ Supreme XT) after implantation in the subcutaneous connective tissue of isogenic mice. One hundred and thirty five male isogenic BALB/c mice were randomly assigned to 12 experimental and 3 control groups, according to the implant...

The aim of this study was to compare the roughness of the surface of one nanofill (Filtek Supreme XT 3M Espe, St. Paul, USA) and one silorane (Filtek Silorane, 3M Espe, St. Paul, USA) composite after polishing. Five specimens of each composite were polymerized under a polyester strip for 40 seconds. After curing four probes were polished with different Sof-Lex discs and one probe with Pogo for ...

Aim: The study evaluated the efficiency of various finishing and polishing systems and the effect of finishing and polishing time by using various procedures on surface roughness and hardness of silorane based (FiltekP90) and methacrylate based (Z100) restorative materials. Method: The surface roughness and surface hardness were measured using a profilometer and Vickers hardness tester respecti...

Objective: This study aimed to evaluate the suitability of one specific silorane-based composite for the application as a repair material for different substrates. Materials and methods: Truncated cones of composites fabricated and thermocycled for 6000 cycles to serve as a substrate were made of two commercially available dimethacrylate-based composites (DBC) (Filtek Supreme and Clearfil APX) ...

background: the clinical success of sandwich technique depends on the strength of resin-modified glass ionomer cement (rmgic) bonding to both dentin and resin composite. therefore, the shear bond strength (sbs) of resin composite bonded to rmgic utilizing different resin adhesives versus a gic-based adhesive was compared. materials and methods: in this in vitro study, 84 holes (5×2 mm) were pre...

background and aims. studies have shown decreased bond strength of composite resin to human and bovine bleached enamel. this study evaluated the effect of sodium ascorbate and delayed bonding on the bond strength of two adhesive systems to bleached enamel. materials and methods. the labial surfaces of 150 sound bovine incisor teeth were abraded with abrasive paper. the teeth were randomly divid...
