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.

Shining new light on dental biomaterials: NIOM is hosting Northern Lights 2018

NIOM is host and local organizer of the sixth annual Northern Lights International Symposium which is taking place July 30-31st in Oslo. The main topics of the conference are bioactive materials and light transmission through ceramics and composites. The symposium aims to bring together almost 60 leading experts from 16 countries and over two days they will work through the topics through presentations and discussions, leading to a consensus that will be covered in a wide variety of post-conference publications.

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.

Lysherding – så enkelt og så vanskelig.

For kort herdetid kan føre til mangelfull herding (polymerisasjon) av komposittmaterialer. For lang herdetid kan øke risiko for varmeskade på oralt bløtvev og pulpa. Herdelampens lysstyrke (irradians) reduseres når avstanden øker mellom lysutgangen og materialflaten.
For å opprettholde lysdosen som kreves for tilstrekkelig herding, må herdetiden økes. Kortere lysherdingstider enn omtrent 10 sekunder kan føre til utilstrekkelig herding av materialet.

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.
