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.

Are LED Lights a Hazard to Human Health?
There is no evidence that the general public is at risk of direct adverse health effects from Light Emitting Diodes (LEDs) when the lights (lamps for lighting and displays) are in normal use, the European Commission stated in a recent published Opinion. The Scienti c Committee on Health, Environmental and Emerging Risks (SCHEER), having a NIOM scientist as expert member, authored the Opinion.

Light curing can be a process that does not receive the attention it requires, but there are simple ways to optimise the light curing procedure.

BPA has been reported to leach from dental materials, however, there is currently little reason for concern about adverse health outcomes due to exposure from dental materials alone.

New animal model of extrinsic dental erosion-Erosive effect on the mouse molar teeth
Human experiments on dental erosion are unethical because of the
irreversible loss of dental hard tissues when exposed to acids.
Therefore, studies using animal models are of high importance since
they represent clinical situations. Based on the present results it can be
concluded that cola drink (phosphoric acid, pH=2.27) exhibited
higher erosive effect on mouse mandibular molars compared to sports
drink (citric acid, pH=3.39). This new animal model of extrinsic
dental erosion where lesions of different severity can be created is
suitable for further studies that will improve our understanding of the
disease. The present method with transversely ground molars observed
in SEM allows a registration of erosive lesions and lesion depths in small
teeth like mouse molars. Both studies on the salivary influence (e.g. by
using knockout mice) and the studies on the effect of fluoride on development of erosive lesions are warranted.
Optimizing quality and safety of dental materials
Optimizing quality and safety of resin‐based materials need coherent strategies. Proper handling and polymerization increase the rate of conversion and thus minimize the content of residual monomers. Measures to reduce biofilm accumulation at the tooth‐restoration interface could prevent or reduce the most common reason for restoration failure, recurrent caries.
Presence and leaching of bisphenol a (BPA) from dental materials
BPA has been reported to leach from some resin-based dental restorative materials and materials used for orthodontic treatment. To confirm and update previous findings, especially in light of the new temporary lower threshold value for tolerable daily BPA intake, leaching of BPA from 4 composite filling materials, 3 sealants and 2 orthodontic bonding materials were investigated.
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.
