Effect of Chlorhexidine digluconate on endodontic sealers - A recent study showed increased antimicrobial activity of three endodontic sealers after chlorhexidine contact. Cell toxicity and physicochemical properties were mostly negatively affected.
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.
NIOM at NTF - NIOM's Maria Pain and Aida Mulic at this year's NTF in Norway. Pain held a lecture about Microbiology in dentistry.
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.

Join our symposium at PER-IADR - On September 16, NIOM and NOF will host a joint symposium titled “Biological and clinical aspects of modern composite techniques”. – NIOMs Frode Staxrud will chair the event, says Jon E. Dahl, NIOMs CEO. Staxrud is joined by Pekka K. Vallittu from the University of Turku, NIOMs Jan Tore Samuelsen and Niek Opdam from Radboud […]
NIOM to PER-IADR Oral Health Research congress 2022 - You will be able to meet NIOM on three different occasions at the PER-IADR in Marseille. From the exhibition area, to the poster section, to the symposium “Biological and clinical aspects of modern composite techniques” with NIOMs Frode Staxrud as chair.

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 substance or mask discoloration. Pre-treatment of tooth substance and restoration, cement composition and strength, mixing and application method, depth […]
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.
