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.

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.

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.

The Norwegian National Network Group for Oral Health Research and Innovation
In 2014, the Norwegian Ministry of Health and Care Services published a white paper on the status of oral health research in Norway. The white paper emphasised that there were too many small research groups in the country, they focused on too many diverse subjects, and there was too little national and international collaboration.
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.
Saliva proteins may protect against erosive tooth wear
A new study on protein profiles in saliva show unexpected promise. The results point to the possibility that the presence of certain proteins can protect against erosive tooth wear.
From the instrument park: Liquid-induced erosion simulator
NIOM’s new cycling device simulates the exposure of different drinks on dentition and dental materials. By combining the effects of saliva, abrasion and tooth brushing, the researcher can simulate a clinically relevant environment.

Effect of silica nano-spheres on adhesion of oral bacteria and human fibroblasts
This study investigated the effect of surface nano-patterning on adhesion of an oral early commensal colonizer, Streptococcus mitis and the opportunistic pathogen Staphylococcus aureus and human fibroblasts (HDFa) in a laminar flow cell.
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.
