Relation between In Vitro Toxicity and the Thiol-Reactivity of Methacrylates in Resin-Based Biomaterials -

In this study we aimed to further map the suggested relation between GSH-depletion and methacrylate toxicity by comparing the molecular effects of methacrylate exposure and GSH-depletion by inhibiting GSH-synthesis.

Cell toxicity of methacrylate monomers-the role of glutathione adduct formation. -

Polymer-based dental restorative materials are designed to polymerize in situ. However, the conversion of methacrylate monomer to polymer is never complete, and leakage of the monomer occurs. It has been shown that these monomers are toxic in vitro; hence concerns regarding exposure of patients and dental personnel have been raised.

Role of thiol-complex formation in 2-hydroxyethyl-methacrylate-induced toxicity in vitro -

Methacrylate monomers that are found to leach from cured resin-based dental materials induce biological effects in vitro. The underlying mechanisms have not been fully elucidated although involvement of increased cellular reactive oxygen species (ROS) and DNA-damage has been suggested
