OBJECTIVES Resin (co)monomers may be released from restorative dental materials and can diffuse into the tooth pulp or the gingiva, and can reach the saliva and the circulating blood. Genotoxic potential of some dental composite components has been clearly documented. The genotoxic effects of xenobiotics can represent a possible step in tumor initiation and/or embryotoxicity/teratogenesis. A mo...

We report the full characterization of a photocurable dimethacrylate-based formulation modified with small amounts (1 and 3 wt%) polystyrene-block-poly(ethylene oxide) (PS-b-PEO) block copolymer (BCP). The UV curable is mixture bisphenol A bis(2-hydroxy-3-methacryloxypropyl)ether (Bis-GMA) triethylene glycol dimethacrylate (TEGDMA) contains phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (Irga...

OBJECTIVE This study evaluated the performance of different adhesive systems in fiber post placement aiming to clarify the influence of different hydrophobic experimental blend adhesives, and of one commercially available adhesive on the frictional retention during a luting procedure. MATERIAL AND METHODS One luting agent (70 Wt% BisGMA, 28.5% TEGDMA; 1.5% p-tolyldiethanolamine) to cement fib...
