Bisphenol A in dental sealants and its estrogen like effect

Indian Journal of Endocrinology and Metabolism, 2012
Bisphenol A or BPA-based epoxy resins are widely used in the manufacture of commercial products, including dental resins, polycarbonate plastics, and the inner coating of food cans. BPA is a precursor to the resin monomer Bis-GMA.

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

Embryonic exposure to bisphenol A glycidyl methacrylate induces craniofacial cartilage malformation via NLR signaling pathway in zebrafish

Ecotoxicology and Environmental Safety
Bisphenol A (BPA) can combine with glycidyl methacrylate to form bisphenol A glycidyl methacrylate (Bis-GMA). Bis-GMA is an important industrial raw material and a significant component of dental resin materials.

Analysis of Major Components and Bisphenol A in Commercial Bis-GMA and Bis-GMA-based Resins Using High Performance Liquid Chromatography.

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 ...

Investigation on synthesis and properties of isosorbide based bis-GMA analogue [PDF]

Journal of Materials Science: Materials in Medicine, 2012
The aim of this work was to synthesize and investigate properties of a novel dimethacrylic monomer based on bioderived alicyclic diol--isosorbide. Its potential as a possible substitute of 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl]propane (BISGMA), widely used in dental restorative materials and suspected for toxicity was assessed. The novel

Evaluation Of BIS-GMA Release In Different Types Of Composites

Erzincan Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021
ÖZET Amaç: Kompozit malzemelerin sıklıkla yapısında yer alan BIS-GMA, polimerizasyondan sonra reaksiyona girmeden kalabilmektedir. Artık monomerlerin bilinen zararlı etkileri nedeniyle, dental malzemelerden salınan monomer miktarlarının belirlenmesi çok önemlidir.
