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.
Side effects of chemical compounds used in dental clinics - The work at a dental clinic implies getting in contact with different chemical substances, which may cause temporary or permanent injury to the staff, primarily allergic reactions, but also local irritation, carcinogenic or toxic effects. Dentists and dental assistants belong to the professional groups most frequently experiencing work-related eczema.

Tips and insights from NIOM’s webinar: Recommended use of Fluoride - "Recommended use of Fluoride" was NIOM's first webinar in 2018. Participants from the Nordic countries and the rest of the world were present when Senior Scientist Aida Mulic covered topics such as fluorides for caries reduction, the most effective and recommended fluoride products, patients at high caries risk and dental erosive wear.



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.
