Estrogenicity of bisphenol A and bisphenol A dimethacrylate in vitro

Journal of Biomedical Materials Research, 1999
Although pit and fissure sealants have been utilized extensively in dentistry as a way of preventing occlusal caries, results described by Olea et al. (1996) raised concerns about the safety of sealants and other resin-based dental materials due to the reported presence of bisphenol A (BPA) and its dimethacrylate ester (BPA-DM). Although the release of

Alkenylidene bisphenols, a new class of bisphenol bactericide

Journal of Medicinal Chemistry, 1979
Alkenylidene bisphenols are prepared by condensation of an appropriate phenol with a haloacetaldehyde, followed by base-induced elimination, or by condensation of the corresponding aryl methyl ether, elimination, and deprotection of the phenol with boron tribromide. The resulting compounds may be further elaborated by reactions on the aromatic nucleus.

Substitution of bisphenol A: a review of the carcinogenicity, reproductive toxicity, and endocrine disruption potential of alternative substances

Critical Reviews in Toxicology, 2020
The use of bisphenol A (BPA) is restricted due to its reproductive toxicity and endocrine disrupting (ED) properties. The public concern and regulatory restrictions on BPA stimulated the development of alternative substances to replace BPA.

Bisphenol A in Dentistry.

The European journal of prosthodontics and restorative dentistry, 2020
Bisphenol-A, an organic synthetic compound, has been present in many consumer plastic products and food packaging since the 1960s. Nowadays, Bisphenol-A is widely used in the field of dentistry for the manufacturing of resin materials. Several studies have suggested that Bisphenol-A may cause adverse health effects due to its ability to act as an ...

The pigmentation interference of bisphenol F and bisphenol A

Environmental Pollution, 2020
Bisphenol A (BPA) and bisphenol F (BPF) are widely distributed in the environment and daily consumptions, leading to exposure toward human and environmental animals. The potential risk of bisphenol analogs on pigment and skin health is not well documented.
