The aim of the study was to investigate the metal ion release, surface roughness and cytoxicity for Co–Cr alloys produced by different manufacturing techniques before and after heat treatment. In addition, to evaluate if the combination of materials affects the ion release.

The aims of this in vitro study were to assess if dynamic loading increases the metal ion release of selected dental alloys and to evaluate the cytotoxicity of the released metal ions

Abstract Root canal sealing materials may have toxic potential in vitro depending on the cell line, cytotoxicity assay, material chemistry, and degree of polymer curing. The aims of the present study were to detect leaching components from epoxy- or methacrylate-based root canal sealers and to investigate the degree of cytotoxicity after exposure to extracts from […]

The aim of this in vitro study was to investigate possible involvement of cytochrome P450 (CYP) enzymes in modifying the toxic potential of 2-hydroxyethyl-methacrylate (HEMA). Primary cultures of CYP expressing rat alveolar type 2 cells were exposed to varying concentrations of HEMA. Nuclear translocation of aryl hydrocarbon receptor (AhR) after HEMA exposure (100 μM) was demonstrated by immunocytochemical staining.

The aim of this study was to determine water sorption, water solubility, dimensional change caused by water storage, residual monomers, and possible cytotoxic effects of heat-polymerized carbon-graphite fibre-reinforced composites with different fibre loadings based on methyl methacrylate/poly(methyl methacrylate) (MMA/PMMA) and the copolymer poly (vinyl chloride-co-vinyl acetate).
