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.

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.
Commonly used alloys tested
Cobalt-chromium (Co-Cr) alloys are becoming more and more popular with the rise of milling technology. This makes it more important than ever to make sure that dental restorations based on these materials are safe for patients
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.
Summer greetings
Read about how covid19 is affecting NIOM this summer and fall. Our offices will remain open all summer, though response time may vary.

Cobalt–chromium alloys fabricated with four different techniques: Ion release, toxicity of released elements and surface roughness
ObjectiveTo investigate the metal ion release, surface roughness and cytoxicity for Co–Cr alloys produced by different manufacturing techniques before and after heat treatment. In addition, to evaluate if the combination of materials affects...
Functional, compositional, and regulatory analyses of imported and non‐imported single dental crowns
The aim of the study were to investigate functional and esthetic properties, the composition of the alloy, and the content of hazardous elements of single dental crowns with metal skeleton and fired porcelain.
Dentin to dentin adhesion using combinations of resin cements and adhesives from different manufacturers – a novel approach
The aims of this study were to present a novel method to analyse dentin bond strength and to evaluate the bond strength of combining adhesive systems and resin cement from different manufacturers. Based on the results and within the limitations of this laboratory study, it can be concluded that using alternating combinations of resin cement
and adhesives seem possible and that the resin cement were the weakest components in the bonded dentin-adhesive-cement-complex.
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.
