Be proactive: pointers for safe and effective physical protection in the clinic - None of the tested composite materials was deemed less safe to use. Flow cytometry did not indicate any changes in cell growth pattern or increased cell death.
Concentration of eluted monomers from the composites, in microgram per square centimeter surface area. Toxicity testing of composites - None of the tested composite materials was deemed less safe to use than the others, a recent report from NIOM concluded. The release of monomers from the different composites was similar. Initial cytotoxicity screening of extracts of the materials indicated some differences between the products. However, further evaluations could not verify a cytotoxic potential.
NIOM webinar: Recommended use of fluoride - In this 20 min webinar NIOM Senior Scientist Aida Mulic will present the recommendations for use of fluoride to combat the most common oral diseases, dental caries and dental erosions.
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 presenting at the 2018 NSFT winter meeting in Beitostølen - The Norwegian Society of Pharmacology and Toxicology (NSFT) is holding its 46th annual winter meeting at Beitostølen, Norway, January 25th-28th. The meeting is interdisciplinary. Four NIOM scientists and technical staff are participating with presentations of their research. Managing Director Jon E. Dahl, scientist Jan Tore Samuelsen, technical officers Solveig Uvsløkk and Bergitte P. Olderbø and […]

New PhD candidates to NIOM - Pawel Kallas and Krister Gjestvang Grønlien are PhD candidates from the University of Oslo who have recently come to NIOM to work on collaborative projects. Kallas is a PhD candidate in the Department of Biomaterials, Faculty of Dentistry and Grønlien is a PhD candidate in the School of Pharmacy. Kallas’ project focuses on how nanostructured […]
NIOM and guest scientists celebrate Finland’s centenary - The 6th of December marks 100 years of independence for Finland. The theme for the celebratory year is “Together,” showing that everyone – Finns and friends of Finns – is welcome to take part, just as creating and building the nation were joint efforts.
Guest researchers from Finland and Greece - NIOM has recently welcomed two new guest researchers. Mervi Puska from Finland and Foteini Machla from Greece.

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.
Redefining the Phenotype of Dental Caries - To our knowledge, this is the first study to separate patients into more discrete groups based on dental caries experience defined from longitudinal data and the first to study acute increases in DMFT score between two time points. Our hope with doing so is to provide more power in our predictions of genetic influences of dental caries and perhaps lead to better ways of studying the disease based on more specific categorizations of phenotypes.
