    • Airborne exposure to gaseous and particle-associated organic substances in resin-based dental materials during restorative procedures 

      Nilsen, Bo Wold; Jensen, Einar; Õrtengren, Ulf; Bang, Berit; Michelsen, Vibeke Barman (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-16)
      Dental composite dust has been shown to act as a vehicle for methacrylates in vivo/in vitro. The objective of this study was to assess airborne exposure of dental personnel to gaseous and particle‐associated organic constituents from resin‐based dental materials in a simulated clinic. Sampling of total aerosol fractions and gaseous substances was performed by dental students carrying particle filters ...

    • Dose- and time-dependent effects of triethylene glycol dimethacrylate on the proteome of human THP-1 monocytes 

      Nilsen, Bo Wold; Simon-Santamaria, Jaione; Ørtengren, Ulf Thore; Jensen, Einar; Bruun, Jack-Ansgar; Michelsen, Vibeke Barman; Sørensen, Karen Kristine (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-27)
      Triethylene glycol dimethacrylate (TEGDMA) is commonly used in polymer resinbased dental materials. This study investigated the molecular mechanisms of TEGDMA toxicity by identifying its time- and dose-dependent effects on the proteome of human THP-1 monocytes. The effects of different concentrations (0.07– 5 mM) and exposure times (0–72 h) of TEGDMA on cell viability, proliferation, and morphology ...
