Water sorption and solubility of dental composites and identification of monomers released in an aqueous environment. -

The resin composition influences the water sorption and solubility behaviour of composite resin materials. The HPLC analysis of eluted components revealed that triethyleneglycol dimethacrylate (TEGDMA) was the main monomer released. Maximal monomer concentration in the eluate was observed after 7 days.

Dimensional change following setting of root canal sealer materials. -

The study was designed to evaluate a method proposed for measuring dimensional changes of endodontic sealers, and to assess the dimensional changes of 11 commercial sealers after prolonged storage in water.

Cytotoxic effects of visible light-cured dental materials -

Resin based materials cured by blue light are used for the majority of dental restorations in the Nordic countries. There is little knowledge of the potential biological effects of the photosensitisation induced by resin based dental materials at the cellular level.

Rat lung inflammatory responses after in vivo and in vitro exposure to various stone particles -

Rat lung alveolar macrophages and type 2 cells were exposed for 20 h in vitro to various stone particles with differing contents of metals and minerals (a type of mylonite, gabbro, feldspar, and quartz). The capability to induce the release of the inflammatory cytokines interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-alpha), and macrophage inflammatory protein-2 (MIP-2) was investigated.

Fyllingsterapi i Norge – materialvalg, holdbarhet og årsaker til revisjon -

Bruken av tannfyllingsmaterialer, deres holdbarhet og årsakene til at fyllinger må skiftes, er kartlagt gjennom en spørreundersøkelse blant private og offentlig ansatte allmennpraktiserende tannleger.

Valg av fyllingsmaterialer i offentlig tannpleie -

En spørreundersøkelse i Vestfold har kartlagt offentlig ansatte tannlegers valg av fyllingsmateriale i gitte behandlingssituasjoner. Tannfargede materialer var de fleste tannlegers førstevalg for de fleste fyllingstyper. Kompomer dominerte i behandlingen av primære tenner og kompositt blant permanente tenner.
