Photopolymerization is an environmentally-friendly, non-destructive, safe and solvent-free method. Moreover it guarantees low energy consumption. Therefore the photopolymerization used in many scientific disciplines, including dentistry for production photocurable dental materials. In this work, new photoinitiating systems based on camphoroquinone (CQ) iodonium salts with tosyl anion initiation...

As a part of this study, mathematical model based on two-compartment pharmacokinetic system with general fractional derivatives was developed. Its aim to describe the release BisGMA and TEGDMA monomers from composite core resin over three time periods. For purpose, five Clearfil Photo Core samples were prepared elution measured using high performance liquid chromatography at 1, 7 28 days post-i...

Methacrylic derivatives of bile acids have been synthesized for use as monomers in dental composites. Polymeric dental materials are known to leach cytotoxic unreacted monomers and degradation products. In this study, the in vitro cytotoxicity of bile acids and their derivatives towards 3T3 fibroblasts has been evaluated by colorimetric MTT assay and compared with that of the common dental mono...

The dependence of the photoinitiator concentration on degree conversion, mechanical properties and colour appearance dental materials was studied. Alterations due to changes in were-undertaken. Test samples prepared by photopolymerizing BisGMA TEGDMA presence camphorquinone (CQ) were submitted analyses, i.e., compressive diametral tensile strength Barcol hardness tests CIELAB analysis. showed a...

The purpose of this study was to investigate the effect of different polishing methods on color stability of posterior, universal and nanohybrid composite resin restorative materials upon exposure to a staining agent. Twenty-five specimens were prepared for each of 5 different composite resins (Filtek Z250, Filtek P60, Quadrant LC, Grandio and Filtek Supreme). Specimens were divided into 5 grou...
