Cell toxicity of HEMA -

Cell toxicity of HEMA – the role of oxidative stress The methacrylate monomer 2-hydroxyethyl methacrylate (HEMA) is commonly used in polymer-based dental restorative materials. Several studies have shown that HEMA is toxic in vitro. Increased oxidative stress has been suggested as a key event in this response. Objective: To study the relation between decreased viability […]

Depth of cure -

A stainless steel mould of diameter 4 mm was placed upon a film, transparent to the LED lamp emission, and then placed on a glass microscope slide. The mould was slightly overfilled with the test material (i.e. Filtek Z250, A3 or Tetric EvoCeram, A3). A second strip of film was placed on the test material […]
