Here is a small summary of our first half-year activities.



We have published a number of articles so far this year. Here is a small sample that may interest you:

Presentations at conferences

Director Jon E. Dahl spoke at the yearly convention of the US Society of Toxicology.
Scientists Jan Tore Samuelsen and Simen Kopperud both presented work at the IADR General Session in Boston, Massachusetts.
Director Jon E. Dahl, Head of Laboratory Hilde Kopperud and Senior Scientist Ellen Bruzell held a seminar for the Icelandic Dental Association.


The “NIOM TESTED” programme

Director Jon E. Dahl and Head of Laboratory Hilde Kopperud held a presentation of the NIOM TESTED programme during IDS 2015 in Cologne, Germany. The NIOM TESTED programme is a system for quality evaluation of dental products. In our experience, the CE marking of dental products has become a bare minimum of product evaluation for trade approval, and is not sufficient to demonstrate the quality of a material. The NIOM TESTED verification will ensure that your product holds the highest standards. We were so pleased with the great turn-up at this presentation.


Expert work groups

Senior Scientists Ellen Bruzell and Arne Hensten have participated in a working group of the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR). Their work has resulted in the report “Scientific Opinion on: The safety of dental amalgam and alternative dental restoration material for patients and users” which was issued in April.

Senior Scientist Arne Hensten has been an advisor to the World Health Organization (WHO) and European Centre for Environment and Health conference in Bonn in June concerning health sector involvement in the Implementation of the Minamata Convention: Mercury exposure assessment and prevention. Arne Hensten presented a summary of the SCENIHR Opinion on the safety of dental amalgam.



NIOM’s experts are strongly involved in standardization activities enhancing the quality of medical devices used in dentistry (ISO/TC 106; CEN/TC 55 Dentistry) and in the development of standards for safety evaluation of medical devices (ISO/TC 194; CEN/TC 206 Biological evaluation of medical devices).

NIOM also participates in Quality management and corresponding general aspects for medical devices (ISO/TC 210; CEN-CLC/TC 3). New work has recently started in ISO/TC 210/WG 6: Application of post market surveillance systems to medical devices.

The European Organization for Standardization (CEN-CENELEC) published the technical report: CEN-CLC/TR 14060:2014: Medical device traceability enabled by unique device identification (UDI). Arne Hensten was leader of the working group CEN-CENELEC/TC 3/WG3: Medical device traceability that developed it.

On 29 June, ISO published a revised version of ISO 12836, the standard for assessing accuracy of scanning devices used in dentistry to create digital impressions. The revision seems minor, but in restricting the scope to laboratory rather than intra-oral scanners, it acknowledges that the test pieces prescribed for assessment are unsuitable for intra-oral scanners, which use pattern recognition techniques. Senior Scientist John Tibballs led the revision.


New staff

We are happy to welcome Ida Sofia Refsholt Stenhagen as a new Scientist at NIOM. She holds a M.Sci degree in Medicinal Chemistry from University College London and a D.Phil in Organic Chemistry from the University of Oxford. Her research interests include fluorine chemistry, transition metal catalysis and polymer science. At NIOM she will be working on biocompatibility issues and analyzing new biomaterials.


We look forward to an active autumn for everyone!
