Målet med konferansen er å samle videreutdanningskandidater, stipendiater og forskere til nettverksbygging og til å presentere forskning på tvers av de ulike institusjonene som arbeider innen feltet oral helse.
This year has been an exciting one, both personally and for NIOM. I have taken the reins as the new CEO, and as a company, we continue to ensure that dental biomaterials are safe and effective in the Nordic countries. Research has always been a major obligation for...

Newsletter | December 2023When translucent zirconium-dioxide (zirconia) was launched in 2009 for monolithic and semi-monolithic crowns and FDPs, as an alternative to traditional veneered zirconia, the given clinical recommendations were based on the properties of...
Repair bond strength of bulk-fill composites: influence of different primers and direction of debonding stress
The purpose of this in vitro study between Finnish and Norwegian scientists was to evaluate the effect of different adhesive primers on the repair bond strength of bulk-fill resin composite and short-term hydrolytic stability of the restorative interface before and after accelerated aging. In addition, the effect of the direction of debonding was examined.
Wear is an irreversible process affecting both teeth and dental restorations. A recent laboratory study reported on deterioration of a composite resin (Filtek Z250®), a glass ionomer cement (Fuji IX GP®), and a glass hybrid (Equia Forte®) under different types of wear.
The biocompatibility of resin-based dental biomaterials has been studied widely, mainly by laboratory studies (in vitro). In a newly published paper, Samuelsen and Dahl overview available data and describe how the research strategy is changing to yield more clinically relevant knowledge.
Most of the adolescents in a Norwegian cross-sectional study had snus induced lesions, and one fifth had gingival retractions. The severity increased with the amount of snus boxes used and the duration of the snus use, respectively.
Elemental composition, corrosion resistance and mechanical properties of computer-aideddesign and computer-aided manufacturing fixed retainers versus conventional fixed retainers
This study investigate the elemental composition, corrosion resistance, and mechanical properties of computer-aided design and computer-aided manufacturing (CAD-CAM) retainers versus conventional fixed retainers (FRs).
Profiling of cyclic di-adenyl and -guanyl nucleotides and their precursors and degradation products in bacteria using LC–MS/MS
The 3,3′-linked cyclic dinucleotides (CDNs) of adenosine monophosphate (AMP) and guanosine monophosphate (GMP), cyclic di-AMP (c-di-AMP), cyclic di-GMP (c-di-GMP), and c-GMP–AMP (cGAMP) are second messenger molecules in bacteria that regulate processes, such as biofilm formation, motility, virulence, stress response, and cell wall homeostasis.
The pulp has many important roles as to the function and survival of teeth. Teeth with deep carious lesions should be treated conservatively if possible. There are several treatment options for this purpose, but they all have in common the necessity of finding a reliable and correct diagnose for the «health status» of the pulp before making a treatment decision. Modern approaches to caries treatment have moved from a pure mechanistic view to a more biological view.
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.
