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.

Wear on and inside implants

Wear on the different parts of a dental implant, can cause particle release as well as shorten the lifetime of the implant. A recently published study at NIOM in collaboration with the University of Gothenburg looked at particle release from dental implants in saliva during dynamic loading.

3D printing in odontology

Those who were able to attend the last IDF trade fair in Cologne, the year before the pandemic, saw 3D printers everywhere. There has been a steady growth in the use of 3D printing to produce resin-based appliances. In order to clarify the various 3D methods, NIOM’s Ida Stenhagen has written a review article.

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.

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.
