Safe and sufficient light curing of dental materials - 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.
TMA offers valuable insight of materials properties - Thermomechanical analysis, TMA, can provide valuable information on materials which influence on production conditions for dental restorations that is difficult to obtain by other analytical techniques.
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.
Dental calculus – an exciting time capsule that reveals how ancient humans lived - In the June issue of the Norwegian Dental Association’s Journal, Professor emeritus NJ Nils Jacobsen (now working at NIOM) has publised an article on how dental calculus in skeletal material contains valuable archaeological information

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.
Nrf2 Signaling and Cytoprotection in Human Epithelial Airway Cells Exposed to HEMA - Methacrylates are common constituents of resin-based biomaterials. These materials cure by polymerization of methacrylate monomers, but incomplete polymerization causes leakage and patient exposure to the electrophile monomers.
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.
