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.

Digital dentistry

Digital manufacturing using intraoral scanners appears to provide equivalent fit compared to conventional technique for smaller prosthetic constructions. Milled composites have a less toxic potential compared to traditional light cured directly placed composite restorations.

Dementia. Are dentists protected?

Dementia is a common term for diseases of the brain expressed as the loss of cognitive abilities and activities of daily living. The number of persons with dementia is increasing due to the aging population in the developed countries, and the risk of dementia is higher in the very old age groups.

New BPA-free monomer for dental materials

NIOM guest-researcher Jingwei He has successfully synthesized a BPA-free monomer, which has been evaluated for experimental materials. The conclusion is that the new monomer has potential to be used in commercial dental composites.

Peroxide-free tooth whitening products

The purpose of this study was to compare the bleaching effects of peroxide-free and peroxide-containing tooth whitening products.
After 8 months, no perceivable lightening was noted for the peroxide-free products whereas the teeth treated with peroxide containing bleaching remained lightened.

Effect of methacrylated chitosan incorporated in experimental composite and adhesive on mechanical properties and biofilm formation.

The results of this study show that methacrylated chitosan (CH-MA) may be incorporated into a composite and into an adhesive to reduce biofilm formation on their surfaces. The mechanical properties of the composite were challenged, but flexural strength measurements still met the requirement set in ISO 4049, whereas no differences were observed for the bonding properties of the adhesives.

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.
