INFLUENCE OF FILLER, MONOMER MATRIX AND SILANE COATING ON COMPOSITE RESIN ADHESION
Studia Universitatis Babes-Bolyai Chemia, 2021 This study compared marginal microleakage in case of two dental composite resins: a consecrated commercial Bis- GMA resin- IPS Empress Direct (Ivoclar Vivadent, Lichtenstein)- group A, and a recently introduced Bis- MEPP resin - Gaenial A’Chord (GC R&D ...

Distribution and Excretion of TEGDMA in Guinea Pigs and Mice [PDF]
, 2001 The monomer triethyleneglycoldimethacrylate (TEGDMA) is used as a diluent in many resin-based dental materials. It was previously shown in vitro that TEGDMA was released into the adjacent biophase from such materials during the first days after placement.

Nuclear Magnetic Resonance Spectra of Bis-GMA and Iso-bis-GMA
Dental Materials Journal, 1994 2, 2-Bis [4- (2-hydroxy-3-methacryloyloxypropoxy) phenyl] propane (bis-GMA) is widely used in dentistry as a monomer of composite resin system and their bonding agents. Since bis-GMA is not purified, its isomers and some chemicals such as residual initiator remain in the commercial product. Bis-GMA and iso-bis-GMA were separated from bis-GMA monomer by

Effects of different silane coupling agent monomers on flexural strength of an experimental filled resin composite [PDF]
, 2011 The hydrolytic stability of various silane combinations and their effects on biomechanical properties and water sorption of an experimental dental composite made of bis-GMA and TEGDMA and silane-treated fillers were evaluated. Four silane coupling agents

Analysis of Major Components Contained in Bis-GMA Monomer.
Dental Materials Journal, 1999 The major components contained in commercial Bis-GMA monomer were isolated by thin layer chromatography (TLC) and identified by NMR and high resolution mass spectroscopy. In addition to the two major components already known (Bis-GMA and Iso-bis-GMA), an unknown hydrophilic third major component was isolated and identified as 2,2-[4-(2-hydroxy-3 ...

Dental Materials Journal, 2000 The purpose of this study was to examine the quality of commercially available Bis-GMA because concerns about Bis-GMA and Bis-GMA-based resins have been recently expressed in dentistry. Four major components and bisphenol A, which is a compound of recent controversy, were quantitatively analyzed using high performance liquid chromatography (HPLC) in ...
