End of year greeting - The truly unusual year 2020 is drawing to a close. NIOM’s services have been operational throughout the year thanks to our dedicated staff. 
Deviations in the composition of alloys - A recent NIOM study revealed several irregularities in single dental crowns. The PFM or porcelain-fired-on-metal crowns had been ordered from laboratories both within and outside of Norway. 
Cell line affects the results of toxicity studies - The choice of cell line is of no small matter when conducting in vitro studies. A recent NIOM study has shown how differently five cell lines reacted, although consistently so, when testing for their interaction with two methacrylates. The message is that the choice of cell line will largely affect the results obtained.
New webinar out now - This is a webinar for those who are curious about how dental materials are tested and evaluated. Senior scientist Aida Mulic, DDS, PhD, acts as guide as we visit seven of NIOM's laboratories.
Statistician joins NIOM - NIOM is proud to announce that statistician Linda Vos, PhD, has joined our ranks. Vos studied mathematics and statistics at the Universities of Oslo, Utrecht and Amsterdam. Her PhD is from the University of Oslo. – We’re very happy Linda has chosen NIOM for the next step in her career, director Jon E. Dahl says. […]
New biomaterial engineer at NIOM - NIOM is happy to announce that engineer Freya Sofia Andersen has joined NIOM. Andersen has a background in chemistry, material science and ceramics. 
Arne Hensten, a frontrunner in the world of dentistry, retires - It is with the greatest appreciation we, his colleagues at NIOM, wish dr. odont Arne Hensten a long and healthy retirement. He has been our “grand old man”, tirelessly accumulating and sharing knowledge since he was first employed with us as a researcher in 1974.
Enjoying NIOM’s new direction - - In the past few years, it seems that NIOM’s focus has broadened to include a new range of biomaterials. Maybe because there has been an influx of new people, and new ideas. I find this exciting, says current guest researcher at NIOM, associate professor Qalbi Khan.
When knowledge multiplies - – These are strange times, says Per Vult von Steyern. The Swedish professor in prosthetic dentistry is currently a guest researcher at NIOM. Fortunately, the Norwegian Covid19-restrictions do not restrict him. Quite the contrary. – It’s so quiet, it’s almost meditative, he says, half smiling. Usually, Per divides his time between his responsibilities at the […]LABORATORIES

Hvor mye monomer kan lekke fra en protese? - Protesematerialer inneholder ureagert monomer som kan lekke ut i munnhulen og gi bivirkninger, men i hvor stor grad skjer dette? Tanntekniske laboratorier fremstilte protesematerialer etter sin vanlige metode og NIOM analyserte mengde ureagert monomer, såkalt restmonomer. Kaldakryl hadde større mengde restmonomer enn kokakryl og derfor et større potensiale for å gi bivirkninger. Ett av produktene […]
Adhesion of Escherichia Coli to Nanostructured Surfaces and the Role of Type 1 Fimbriae - In this study a method of producing a large number of identical nanostructured surfaces is presented. E. coli wild type and deletion mutants of the type 1 fimbriae monomers FimA or FimH were tested for their ability to adhere to such surfaces with different interpillar distance of 100, 250, and 500 nm, respectively. An increase in interpillar distance (reduced surface coverage) was associated with reduced adhesion of E. coli wild type and the deletion mutants. In addition, the presence of a functional type 1 fimbria decreased adhesion to the nanopatterned surfaces in comparison to deletion mutants, leading us to the conclusion that there is a relationship between presence of a functional fimbriae and adhesion towards tested surfaces. The hypothesis that the presence of fimbriae had an effect on bacterial attachment to nanostructured surfaces was verified. These current results could provide insight into development of new nano-patterned structures with anti-adhesion bacterial properties.
