New visiting scientists at NIOM
NIOM has welcomed two guest researchers affiliated with Finish universities. Heba Abdelrazik is coming to work on a project connected to her PhD, while Pekka Ahlholm is doing some post-doctorate research. Barely two weeks into their stay, they’re happily settling in.
NIOM scientist wins article of the year award
The American Chemical Society’s (ACS) Journal of Agricultural and Food Chemistry (JAFC) and Division of Agricultural and Food Chemistry honoured senior scientist Silvio Uhlig. Uhlig joined NIOM in June 2022, as the institute’s newest expert on organic and analytical chemistry.

New “Universal bonding agents” reliable for repair of composite restorations.
A recent NIOM-study looked at the reliability of using “Universal bonding agents” in composite-to-composite shear bond strength test. It is worth noting that all nine bonding agents in the study performed as well, or better, than the previous “Gold Standard”, the 3-step etch-and-rinse bonding agent.
Antimicrobial photodynamic therapy gains traction
Killing off bacteria by using light on a thin film covering, sounds intriguing to say the least. The possibilities would be endless, from restorations to self-cleaning environmental surfaces, and on. A collaborative team from NIOM and the University of Oslo (UiO) is currently making strides in this direction.
Electrostimulation therapy for dry mouth
Feeling of dry mouth, often called xerostomia, is not considered a serious medical condition in itself, but it can cause complications like tooth decay and mouth sores. Treating it is therefore imperative for good oral health. A recent paper explores electrostimulation as a treatment option.

Resin-based cements – properties affecting clinical success of indirect restorations
Resin-based cements are frequently used for cementing indirect restorations, especially when the restorations are made of all-ceramic material. The cement has many important roles, e.g. prevent loosening of the restoration and provide optical matching with tooth...
How French dentists manage defective restorations: Evidence from ReCOL the French dental practice-based research network– –A survey study
Repair of DRs is a conservative approach to increase the longevity of these restorations. Despite its limitations, the present study indicates that a significant proportion of Fr-GDPs still do not make sufficient use of dental restoration repair on a routine basis. A lack of knowledge of the concept seems to explain at least part of this situation.
Effect of chlorhexidine digluconate on antimicrobial activity, cell viability and physicochemical properties of three endodontic sealers
The main hypothesis of the study as rejected as exposure to CHX affected sealers’ properties. CHX in contact
with sealer surfaces improved the antibacterial properties of the sealer leachates and reduced cell viability for all sealer leachates, except for freshly mixed PCS. Among the tested sealers, BioRoot RCS leachates presented the highest antibacterial properties and cell viability with and without CHX contact.
LABORATORIES
NIOM TESTED
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.
