WELCOME TO 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.

“Many questions, much praise”

Such reads the headline in the March edition of The Norwegian Dental Journal, referring to NIOM’s first webinar, held February 14th. The journal was in the room as 100 participants logged on across all the Nordic countries, observing, as the webinar was held and the follow-up article reveals more details, such as more background into why NIOM offers webinars, plans for the future and feedback from the participants post-event.

Substantial variations in light curing procedures

Reported data is scarce on light curing times of restorations and irradiance of the curing devices used. In this study we sought to improve the knowledge of such parameters as total light dose applied to a restoration layer and the total potential exposure to reflected light to the dentist’s eyes during a workday. read more

Repair or replace

Repair is the best treatment for defective restorations, most dentists in Norway argue. In a questionnaire study from NIOM and University of Oslo, up to 90 % of the respondents favoured repair rather than replacement of the restoration. read more

Success in light curing

Welcome to our webinar on May 30th. In this webinar our Head of Laboratory, Hilde M. Kopperud, will present topics on light curing techniques and discuss how to avoid pitfalls when buying a new curing lamp. read more

Bacterial biofilm elimination using gold nanorod localised surface plasmon resonance generated heat

Bacterial biofilm elimination using gold nanorod localised surface plasmon resonance generated heat. Highlights: A technique for antibiotic replacement using heat for biofilm elimination is proposed. Gold nanorods exhibit localised surface plasmon resonance upon optical irradiation and when relaxing, absorbed energy is dissipated as heat, which is utilized to kill bacteria. After 5 minutes of near infrared irradiation an average of 71% of early biofilms were eliminated.

A novel etching technique for surface treatment of zirconia ceramics to improve adhesion of resin-based luting cements

Bonding of zirconia crowns and bridges to abutments is important, not only bonding of the thin resin layer to the abutment, but also bonding to the zirconia ceramic is crucial. Both mechanical and chemical adhesion are desired. Mechanical retention of dental porcelain achieved by etching with moderately concentrated hydrofluoric acid is not possible with zirconia ceramics. The purpose of this study was to show that etching is possible with relative low melting fluoride compounds such as ammonium hydrogen difluoride and potassium hydrogen difluoride.

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.
