Bis-GMA affects craniofacial development in zebrafish embryos ( Danio rerio )

Environmental Toxicology and Pharmacology, 2016
Estrogen is a steroid hormone that is vital in vertebrate development and plays a role in a variety of developmental processes including cartilage and craniofacial formation. The effects of estrogen can be mimicked by other compounds found in the environment known as xenoestrogens. Bisphenol-A (BPA) is a known xenoestrogen and is combined with glycidyl

Hybrid waterborne polyurethane/acrylate dispersion synthesized with bisphenol A-glicidylmethacrylate (Bis-GMA) grafting agent [PDF]

Progress in Organic Coatings, 2018
New hybrid waterborne polyurethane/acrylate (WPUA) dispersions were synthesized by grafting with bisphenol-A-glycidyl dimethacrylate (Bis-GMA) in order to create chemical bonds between polyurethane and polyacrylate chains.

Fractography of a bis-GMA Resin

Journal of Dental Research, 1989
The fracture behavior of a bis-GMA resin was studied by means of the double-torsion test. The fracture parameter measured was the stress-intensity factor. Fracture occurred in either a stick-slip (unstable) or continuous (stable) manner, depending upon the test conditions.

Effects of water on the long‐term properties of Bis‐GMA and silylated‐(Bis‐GMA) polymers

Journal of Applied Polymer Science, 2007
AbstractBis‐GMA (2,2‐bis‐[4‐(2‐hydroxy‐3‐methacryloxypropoxy)phenyl]propane) is a viscous hygroscopic monomer which is used with triethyleneglycol‐dimethacrylate (TEGDMA) for dental restorations. Bis‐GMA was silylated with dimethyl‐isopropyl‐siloxane and further polymerized in order to increase water resistance and viscosity.

Residual monomer (Bis‐GMA) of composite resins

Journal of Oral Rehabilitation, 1982
SummaryA method of measuring residual monomer (Bis‐GMA) is described. In addition, the percentage of residual monomer eluted into water from composite resins after setting was compared for several commercial products.

BIS-GMA–BASED RESINS IN DENTISTRY: ARE THEY SAFE?

The Journal of the American Dental Association, 1999
The authors critically surveyed research dealing with the release of resin components from dental composites and the potential of these agents to mimic or disrupt estrogenic cell responses.The studies reviewed included those on synthetic methods used to make bisphenol A glycidyl methacrylate, or BIS-GMA, and the biological effects of this resin in cell

Water sorption in a bis(GMA)/TEGDMA resin

Journal of Biomedical Materials Research, 1984
AbstractSome water sorption–desorption properties of a heat‐cured copolymer of bisphenol‐A‐glycidyl methacrylate/triethylene‐glycol‐dimethacrylate [bis(GMA)/TEGDMA] were investigated during three sequential water sorption–desorption cycles at 60, 37, and 60°C.

Shear bond strength of Bis-GMA resin and methacrylated dendrimer resins on silanized titanium substrate

Dental Materials, 2005
Objectives: The study compared the bond strengths of three resins, Bis-GMA and two novel experimental methacrylated polyester dendrimer resins to grit-blasted titanium substrate with three silanes.

An Investigation into the Fracture Behavior of a Particulate-filled bis-GMA Resin

Journal of Dental Research, 1987
Dental composites are being increasingly used to restore occlusal surfaces of posterior teeth. If these restorations are not to fracture in service, an understanding of their fracture behavior is essential. The fracture parameter used is the stress-intensity factor at crack instability (K IC )

An evaluation of BIS‐GMA resin pit and fissure coatings

Australian Dental Journal, 1979
Abstract— A review of studies on the microleakage, retention, durability, and cariostatic efficacy of BIS‐GMA resin fissure sealants suggests that newly‐erupted permanent molars benefit least but the benefit for premolars is consistently high. Problems arising in the assessment of the sealants in clinical trials are discussed.
