Substantial variations in light curing procedures

Reported data is scarce on light curing times of restorations and irradiance of the curing devices used. In this study we sought to improve the knowledge of such parameters as total light dose applied to a restoration layer and the total potential exposure to reflected light to the dentist’s eyes during a workday. read more

Research for patient safety

The Nordic seminar entitled “45 Years of Research for Patient Safety” (Forskning og pasientsikkerhet i 45 år) was organized by NIOM on behalf of the Ministry of Health and Care Services. The seminar on May 8th and 9th marked the Norwegian presidency of the Nordic Council of Ministers in 2017 and the 45th anniversary of NIOM. read more

Water sorption and solubility of polyamide denture base materials

Some patients experience adverse reactions to poly(methyl methacrylate)-based (PMMA) dentures. Polyamide (PA) as an alternative to PMMA has, however, not been well documented with regard to water sorption and water solubility. The aim of this in vitro study was to measure water sorption and water solubility of two PA materials compared with PMMA, and to evaluate the major components released from the PA materials and the effect on hardness of the materials.

Kemiske stoffers skadevirkninger på tandklinikker (Side effects of chemical compounds used in dental clinics)

The work at a dental clinic implies getting in contact with different chemical substances, which may cause temporary or permanent injury to the staff, primarily allergic reactions, but also local irritation, carcinogenic or toxic effects. Dentists and dental assistants belong to the professional groups most frequently experiencing work-related eczema. The chemical substances may originate from dental materials, such as mercury from amalgam and monomers from resin based materials. The substances may be released during preparation, polishing and removal of restorations. In addition, different biocides/chemical disinfectants are used for both clinical an infection control purposes. Finally, medical gloves contain allergenic latex protein and rubber chemicals and may cause irritant eczema. Basically, damages can be prevented by substitution of hazardous substances, the choice of approved products, compliance with set threshold limits and thorough planning of the work considering health aspects including the preparation of local guidelines. As development of injury follows either direct contact or inhalation of chemical substances, the damage can be prevented by measures such as the use of “no touch technique”, high-volume evacuation reducing spatter and aerosol formation and proper use of personal protective equipment in the form of protective gloves and eyewear and surgical masks.

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.
