Welcome to NIOM

Dear clients

We would like to inform you that NIOM is operational and carrying out scheduled test activities. We support, and follow, the national guidelines regarding the COVID-19 outbreak. Precautions are taken to ensure sustainable safeguards for our staff members and activities.

Dear dental teams
Our services are operational. You may continue to direct any clinically relevant questions regarding use and selection of dental materials to us. As the Nordic competency center of dental materials, we are here to help.

Any changes caused by the current situation will be posted on our website.

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.

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.

Fabrication techniques and ion release in cobalt-chromium alloys

A recent study tested the behaviour of cobalt-chromium alloys under corrosive conditions mimicking the acidity observed in oral biofilm. Cobalt-chromium has become the alloy of choice for the framework of porcelain-fixed-to-metal (PFM) prosthetics also in combination with titanium implants. The alloy specimens were fabricated by both traditional casting, by milling and by laser melting and sintering.

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.

LABORATORIES

NIOM TESTED

NIOM has established a programme for the quality evaluation of a number of dental products. The evaluation is based on testing of the products according to methods in relevant ISO and other standards, or according to other well-established and documented test methods. Products fulfilling the set requirements are granted permission to use the NIOM TESTED quality seal. The NIOM TESTED quality seal confirms that the product meets the requirements specified by NIOM.
