Influence of additives on the properties of Bis-GMA/Bis-GMA analog comonomers and corresponding copolymers

Dental Materials, 2007
The purpose of this study was to evaluate the effect of two additives: propionaldehyde (aldehyde) and 2,3-butanedione (diketone) on the properties of Bis-GMA diluted with TEGDMA and the synthesized Bis-GMA analogs, propoxylated Bis-GMA (CH(3)Bis-GMA) and propoxylated fluorinated Bis-GMA (CF(3)Bis-GMA).Nine experimental comonomers were prepared ...

Synthesis, characterization and evaluation of urethane derivatives of Bis-GMA

Dental Materials, 2003
The aims of the study were to synthesize derivatives of Bis-GMA having pendant n-alkyl urethane substituents and to characterize and evaluate their physicochemical properties.Stoichiometric amounts of Bis-GMA and n-alkyl isocyanates were reacted in dichloromethane with dibutyltin dilaurate as a catalyst.

Studies on Hemolytic Activity of Bisphenol A Diglycidyl Methacrylate (BIS-GMA)

open access: yesJournal of Dental Research, 1978
To clarify the high hemolytic activity of BIS-GMA, the molar concentration producing 50% hemolysis (H 50 ) and the partition coefficient in-octanol-water were determined using BIS-GMA and various types of methacrylates.

Isocyanato- and Methacryloxysilanes Promote Bis-GMA Adhesion to Titanium

open access: yesJournal of Dental Research, 2005
In dentistry, adhesion promotion with 3-methacryloyloxypropyltrimethoxysilane is usually sufficient, but its hydrolytic stability is a continuous concern. The hydrolytic stability of an alternative, 3-isocyanatopropyltriethoxysilane, was compared with that of conventional 3-methacryloyloxypropyltrimethoxysilane.

Post-irradiation polymerization of composites containing bis-GMA and TEGDMA

Dental Materials, 1999
This study was conducted to evaluate the effect of the amount of TEGDMA on post-irradiation polymerization of bis-GMA based composites.Four experimental composites containing bis-GMA and TEGDMA at the ratios (w/w) of 75/25, 70/30, 67/33, and 50/50 were prepared.

Properties of Sealants Containing Bis-GMA and Various Diluents

open access: yesJournal of Dental Research, 1978
Properties of commercial and a series of experimental pit and fissure sealants, based on Bis-GMA were determined using rapid test procedures. By proper selection of monomeric diluent and addition of a photocrosslinking agent, the characteristics of sealant formulations can be varied widely.
