Welcome to NIOM

NIOM works to ensure that dental biomaterials are safe and effective. We undertake research, participate in standardisation and provide clinically 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 independant test laboratory delivers accurate and independant data accepted for third-party evaluations of dental materials and instruments.

NIOM follow the governments guidelines and rules during the COVID-19 pandemi. NIOMs staff take all neccessary precautions, and the institute remain fully operational.

Visit at Eastman Institute

We at NIOM were so lucky to get to visit Eastman Institute in Stockholm last week. We were welcomed by Andreas Cederlund, Wedad Hammoudi and the rest of their personnel. It was a most interesting visit, where we got a tour, joined in on some interesting discussions,...

Electrostimulation therapy for dry mouth

Feeling of dry mouth, often called xerostomia, is not considered a serious medical condition in itself, but it can cause complications like tooth decay and mouth sores. Treating it is therefore imperative for good oral health. A recent paper explores electrostimulation as a treatment option.

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.

Effect of chlorhexidine digluconate on antimicrobial activity, cell viability and physicochemical properties of three endodontic sealers

The main hypothesis of the study as rejected as exposure to CHX affected sealers’ properties. CHX in contact
with sealer surfaces improved the antibacterial properties of the sealer leachates and reduced cell viability for all sealer leachates, except for freshly mixed PCS. Among the tested sealers, BioRoot RCS leachates presented the highest antibacterial properties and cell viability with and without CHX contact.

Photoactive Zr-aromatic hybrid thin films made by molecular layer deposition

In this work, we have developed a new MLD process for fabricating photoactive hybrid thin films based on Zr clusters and aromatic 25D-BDC organic linkers. The amorphous and uniform films display high absorption in the visible part of the spectrum. Moreover, we show that the type of the organic ligand and its functional groups can be used to tune the optical properties of Zr-organic hybrids, as shown by the Zr-2A-BDC and Zr-26-NDC systems in this work.

Potential of «universal» bonding agents for composite repair

In this in vitro study, testing shear bond strength of composite-to-composite bonding, the new universal bonding agents performed similar and for some agents better than the ‘Gold Standard’, 3-step etch-and-rinse bonding agent. New simplified bonding procedures seem reliable for repair of composite.

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.
