NIOM scientists develop new etching technique for zirconia ceramics – improves adhesion of resin cements -

NIOM scientists have developed a surface etching technique that improves adhesion between resin cement and zirconia. This new method called Melt Etching is based on melting of fluoride compounds, and can be readily adapted by dental technicians.

Standardization and patient safety – ensuring that dental materials are safe and effective -

When considering patient safety, the quality and adequate function of a material or device is given by its mechanical strength, chemical stability and biocompatibility. Standards allow for ease of trade, since the product or service is well described, so that the manufacturer and the consumer have a common understanding of its expected performance.

Nylon dentures may be a good alternative -

Polyamide, or nylon, is an alternative material for removable dentures. They do not release allergens and have acceptable water sorption. Nylon dentures are thus promising, although they still lack clinical documentation.

Essentials of dental bonding -

As general practitioner working with patients on daily basis, Frode Staxrud’s main research interests concentrates on clinical dentistry; in particular phenomena concerning “Minimal […]

Occupational hazards in dental clinics -

Dental personnel have the potential of being exposed to a variety of chemicals during the working day, many of which may cause temporary or permanent injury. A recent article co-authored by NIOM scientist Jan Tore Samuelsen in “Tandlægebladet” breaks down the risks dental personnel face during their working day in terms of exposure to a variety of chemicals.

Hardness testing of dental materials and tooth substance -

Hardness is an important mechanical property of dental materials and is defined as the resistance to permanent surface indentation. NIOM has recently acquired a new hardness tester, and the instrument is used in a range of different research projects.
