Webinar: Fluor and fluorider
Join our webinar on the 12th of February. We’ll talk about fluor and fluorider, and how to meet fluor sceptics
New doctorate at NIOM
On December 5th, NIOM scientist Amund Ruud successfully defended his doctoral thesis at the University of Oslo. The thesis Novel Materials and Operando Studies for Lithium-Ion Batteries explores new materials for lithium-ion batteries.

NIOMs first year with NORCE
NIOMs first year with NORCE, has been about business as usual as well as gearing up for the future.
Magic in the workshop
It’s not quite Gepetto’s workshop, but magic still happens at NIOM’s instrument workshop. The two toolmakers both have engineering backgrounds, as well as a combined 42 years of experience at NIOM.
Why do research at NIOM?
Every year NIOM welcome guest researchers, Ph.D candidates and Master students to our midst. Read about the experience of our current host of Master students.
Do fluoride and BHT in toothpaste pose risks for your patients?
Read why NIOM researchers, Drs. Aida Mulic and Ellen Bruzell, agree with recent risk assessments on fluoride and butylated hydroxytoluene, BHT.
Clinical relevance of HEMA-toxicity studies
Several studies show “leakage” of methacrylates during, and shortly after, treatment resin based dental materials. Read about the clinical relevance here.
How healthy were the Vikings’ teeth?
Though extensive research has been performed on Viking settlements, few have been from an odontological point of view. Finally, this is changing.

Commentary Guidelines on the benefit-risk assessment of the presence of phthalates in certain medical devices covering phthalates which are carcinogenic, mutagenic, toxic to reproduction (CMR) or have endocrine-disrupting (ED) properties
The guidelines provide a framework to perform a BRA to justify the presence of CMR or ED phthalates in medical devices.
They also describe the evaluation of possible alternatives for these phthalates used in medical devices.
Manufacturers are encouraged to generate data that are needed for the BRA on potential alternatives to be used in medical devices.
Investigation on the antimicrobial activity of chitosan-modified zinc oxide-eugenol cement
The present study showed that a ZOE-based material has an antibacterial effect and that incorporating CH or COS may increase the antibacterial effect depending on the bacterial species. The total release of eugenol from the materials was stable for up to 18 weeks immersion in water. Eugenol therefore contributed to the antibacterial effect on all the material surfaces investigated. S. mutans exhibited the highest susceptibility to eugenol. The compressive strength of the modified materials was reduced but still met the requirements in ISO 3017.

The Scientific Committee on Health, Environmental and Emerging Risks of the European Commission adopted this document at plenary meeting on 18 June 2019.
NIOM Scientist and Head of Laboratory, Hilde M. Kopperud served as external expert.
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.
