Staxrud in Antalya

This week, NIOMs Frode Staxrud, will participate in the European Federation of Conservative Dentistry, the EFCDs meeting in Antalya, Turkey. Staxrud will speak on the subject of minimally invasive dentistry, when and how a dentist might intervene.

New guest researchers at NIOM

New guest researchers at NIOM

NIOM has welcomed five new visiting scientists this fall. They are; Wedad Hammoudi from Sweden, Sigfus Eliasson from Iceland, and from Norway, Sunita Sharma, Amela Tulek, and Anneli Skjold. Hammoudi and Skjold are working with different aspects like esthetics and...


Wear on and inside implants

Wear on the different parts of a dental implant, can cause particle release as well as shorten the lifetime of the implant. A recently published study at NIOM in collaboration with the University of Gothenburg looked at particle release from dental implants in saliva during dynamic loading.

3D printing in odontology

Those who were able to attend the last IDF trade fair in Cologne, the year before the pandemic, saw 3D printers everywhere. There has been a steady growth in the use of 3D printing to produce resin-based appliances. In order to clarify the various 3D methods, NIOM’s Ida Stenhagen has written a review article.

When to intervene in the caries process?

NIOMs Frode Staxrud, DDS, Ph.D., has a new article out, in which he makes recommendations on when to intervene in the caries process for both new and existing caries lesions. He classifies treatments into three intervention levels: non-invasive, micro-invasive , and invasive or restorative strategies.

Sintering temperature accuracy and its effect on translucent yttria-stabilized zirconia: Flexural strength, crystal structure, tetragonality and light transmission

The aim of this study was to investigate how lower and higher sintering temperature deviations in dental furnaces compared to the recommended firing protocols affected certain material properties of different translucency, chemical composition and recommended sintering temperatures, under the null hypothesis that there will not be any differences in properties investigated between the studied groups.

Protein-coated nanostructured surfaces affect the adhesion of Escherichia coli

Nanotopography influences on bacterial adhesion were investigated with surfaces with controlled interspatial nanopillars distances. Surfaces were coated with proteins (fibrinogen, collagen, serum and saliva) prior to E. coli adhesion under flow conditions. PiFM provided chemical mapping and showed that proteins adsorbed both between and onto the nanopillars with a preference to areas between the nanopillars. E. coli adhered least to protein-coated areas with low surface nanopillar coverage, most to surfaces coated with saliva, while human serum led to the lowest adhesion. Protein-coated nanostructured surfaces affected the adhesion of E. coli.



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.
