As recent news articles highlight the dangers of ski wax containing fluorinated compounds, more patients are becoming skeptical towards fluoride in toothpaste. It is vital to be clear that these are two completely different forms of fluorine element with respect to both toxicity and reactivity.

NIOM have 17 laboratories, and a vast, up- to date instrument park. Today we would like to highlight our new key instrument in materials research, nicknamed the SEM.

NIOMs first year with NORCE, has been about business as usual as well as gearing up for the future.

Read why NIOM researchers, Drs. Aida Mulic and Ellen Bruzell, agree with recent risk assessments on fluoride and butylated hydroxytoluene, BHT.

It’s not quite Gepetto’s workshop, but magic still happens at NIOM’s instrument workshop. The two toolmakers both have engineering backgrounds, as well as a combined 42 years of experience at NIOM.

Several studies show “leakage” of methacrylates during, and shortly after, treatment resin based dental materials. Read about the clinical relevance here.

Every year NIOM welcome guest researchers, Ph.D candidates and Master students to our midst. Read about the experience of our current host of Master students.

Though extensive research has been performed on Viking settlements, few have been from an odontological point of view. Finally, this is changing.

NIOM scientist Aida Mulic is among the lecturers behind the symposium “Dental erosion – the new toothache.” Meet her and our CEO, Professor Jon E. Dahl, after the event.

3D-printers open up exciting new fields of research, treatment and testing. This makes one a natural acquisition for NIOM’s instrument park. Read more about which printer we chose, and why.

For stronger and longer lasting dental crowns, a new NIOM study suggests that melt etching is better than sandblasting.

New research shows that the easiest way to help and encourage patients to stop using snus is underutilized.

NIOM’s new mechanical masticator performs wear simulation of oral conditions.

Like it or not – regulatory issues affect the materials and devices offered to us on the European market.

Icelandic dentists are well educated for diagnosis and treatment of dental erosion, but more emphasizes on causative factors are needed. These are the conclusions from a recent questionnaire study among dentists in Iceland.

A new study of veneered zirconia shows that the magnitude of residual stresses can only be estimated reliably from the manufacturers’ thermal expansion coefficients if the veneered prosthesis is cooled slowly after the final firing.

Future resin-based dental materials must combat the reasons current materials fail, mainly secondary caries and fracture, but still be easy for the dentist to use and safe for the patient.

Finding the best colour match for your restorations, crowns and bridges, is often frustrating, but do not despair, as training and practice makes you better and more confident.

The resin cement forms the weakest link for a ceramic restoration. This was found in an investigation of the de-bonding of resin cementation of zirconia or lithium di-silicate ceramic to bovine dentin.

The peroxide-free tooth whitening products are less effective than those based on peroxides and the effect is only transitory. Both peroxide-free and peroxide containing products gave an initial lightening of the tooth color. However, the effects of peroxide-free products were only transitory.

Digital manufacturing using intraoral scanners appears to provide equivalent fit compared to conventional technique for smaller prosthetic constructions. Milled composites have a less toxic potential compared to traditional light cured directly placed composite restorations.

A new standardized mouse model is established for studying extrinsic dental erosion.

Dementia is a common term for diseases of the brain expressed as the loss of cognitive abilities and activities of daily living. The number of persons with dementia is increasing due to the aging population in the developed countries, and the risk of dementia is higher in the very old age groups.

“There are more animals living in the scum on the teeth in a man`s mouth, than there are men in a whole kingdom”.

NIOM guest-researcher Jingwei He has successfully synthesized a BPA-free monomer, which has been evaluated for experimental materials. The conclusion is that the new monomer has potential to be used in commercial dental composites.

Our patients want safe restorations that retain their function for as long as possible. Preventing recurrent caries and improved handling are the best approaches to optimize quality and safety of dental materials, a recent article from NIOM scientists concluded.

In October and November, NIOM is present at the Dental Conventions in Norway, Iceland, Sweden and Finland. Please stop by our stand for a chat!

There is no evidence that the general public is at risk of direct adverse health effects from Light Emitting Diodes (LEDs) when the lights (lamps for lighting and displays) are in normal use, the European Commission stated in a recent published Opinion. The Scienti c Committee on Health, Environmental and Emerging Risks (SCHEER), having a NIOM scientist as expert member, authored the Opinion.

NIOM was host and local organiser for the sixth annual Northern Lights International Conference in Oslo on 30th and 31st July.

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.

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.

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.

Positions as visiting scientist in the field of dental biomaterials research are offered at the Nordic Institute of Dental Materials, NIOM, in Oslo, Norway. PhD candidates and young scientists are especially invited to apply.

These are the conclusions from a recent retrospective, practice-based study conducted by Institute of Clinical Dentistry, University of Oslo and NIOM.

What are the strategies and methods you as a clinician can use to minimize or manage this problem of caries and other infectious diseases in the oral cavity? Attend this webinar and learn more about it!

Reduced follow-ups and increased cost effectiveness were best obtained using preformed metal crowns (PMCs) in children with severely affected primary molars at high caries risk. This is the conclusion of a collaboration study between the City of Helsinki and NIOM.
