Rapport från NIOM: Uedle metaller til dentale kroner og broer. -

Dentale støpelegeringer av uedle metaller er det blitt mange av. I tillegg til nye jernholdige varianter av kobolt-kromlegeringene, dekker betegnelsen også metallet titan. Nordiske tannleger kan dessuten møte legeringer som er populære i andre deler av verden, bl.a. nikkellegeringer fra USA og de billige, kobber-baserte aluminium-bronsene hos pasienter som tidligere er behandlet i Øst-Europa eller Latin-Amerika.

Bond strength of a composite luting agent to alumina ceramic surfaces -

Within the limitation of the conditions of this study, treatment of alumina oxide ceramic surfaces with a plasma spray coating or a low-fusing porcelain pearl layer significantly increased the SBS of a resin luting agent to the ceramic surface.

Pattern of cell death after in vitro exposure to GDMA, TEGDMA, HEMA and two compomer extracts -

In vitro exposure to chemical compounds in dental materials may cause cell death by apoptosis, necrosis or a combination of both. The aim of this paper was to evaluate aqueous extracts of freshly cured compomers Freedom (SDI) and F2000 (3M ESPE), and constituents identified in the extracts, GDMA (glycerol dimethacrylate), TEGDMA (triethylene glycol dimethacrylate) and HEMA (2-hydroxyethyl methacrylate) for their ability to induce necrosis and apoptosis in primary rat alveolar macrophages and the J744A1 macrophage cell line.
