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.

NIOM investigates: do modern dental materials release BPA? -

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.

Komposittmaterialer – utlekking av monomer og cytotoksisitet -

NIOM har på oppdrag fra Helsedirektoratet undersøkt fire komposittmaterialer: ett Own Brand Label (OBL)-materiale, to bulk-fill materialer og et mye benyttet universalmateriale. Det ble funnet ubetydelige forskjeller i utlekket monomer mellom produktene. I en cytotoksisitets-screening med ekstrakter fra produktene var det noe forskjell mellom materialene. Ytterligere molekylærbiologiske undersøkelser viste imidlertid ingen indikasjon på celleskade. Basert på disse undersøkelsene kan ingen av produktene bedømmes som mindre sikre enn de andre.
