Prevention of snus use: Attitudes and activities in the Public Dental Service in the south‐eastern part of Norway

Dental health care professionals have the opportunity to play a key role in tobacco prevention and cessation among adolescents. Snus use has increased in Norway, especially in the age group 16–24, whereas there has been a decline in smoking. This study investigated attitudes and activities related to snus prevention among dental health care professionals working in the Public Dental Service (PDS) in south‐eastern Norway.

Effect of methacrylated chitosan incorporated in experimental composite and adhesive on mechanical properties and biofilm formation

The results of this study show that CH-MA (CH-MA) may be incorporated into a composite and into an adhesive to reduce biofilm formation on their surfaces. The mechanical properties of the composite were challenged, but flexural strength measurements still met the requirement set in ISO 4049, whereas no differences were observed for the bonding properties of the adhesives.

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.
