WELCOME TO NIOM
Nordic Institute of Dental Materials (NIOM) works to ensure that dental biomaterials are safe and effective. We undertake research, participate in standardization and provide clinical relevant advice to the dental health services and health authorities in the Nordic countries. NIOM offers research-based consultancy and accredited testing according to international standards. Our independent test laboratory delivers accurate and independent data accepted for third-party evaluations of dental materials and instruments.NEWS
Great ceremony at doctoral examination in Turku
John Tibballs, senior scientist at NIOM, acted as public opponent at the final doctoral examination for Mr. Durgesh Bangalore Huchaiah.
Webinar: Minimal intervention dentistry
In our next webinar, you will learn about minimal intervention dentistry. The principle is to preserve as much of the natural tooth structure as possible.
NIOM welcomes visiting scientists
Every year we welcome several visiting scientists to NIOM in Oslo. Most come from Scandinavia, and several are return guests.

Comparison of sandblasted, ground and melt-etched zirconia crowns regarding adhesion strength to resin cement
The aim is to compare the adhesion between zirconia and cements attained with melt-etching with potassium hydrogen difluoride, KHF2, with that found when such traditional surface treatments as sandblasting and ceramic stone grinding are employed.
Treatment decisions regarding caries and dental developmental defects in children a questionnaire-based study among Norwegian dentists
When dentists are treating children with dental caries or DDDs, they must decide the most appropriate treatment in each case. The results of the present study showed a notable disparity between clinician’s
treatment choices. In summary, the clinicians based their treatment choice mostly on patient cooperation, prognosis of the tooth and own experience. The results indicate that Norwegian dentists in PDS evaluate each case individually and base their decisions on what they consider is the best for the individual child.
An update on erosive tooth wear – prevalence, registration, etiology, genetic and treatment principles
There is no standard treatment for damages caused by erosive tooth wear, and choice of treatment strategy should be determined on individual basis with emphasis on the minimal invasive intervention.
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.
