Opinions and Treatment decisions for Dental Erosion- Icelandic dentists are well educated for diagnosis and treatment of dental erosion, but more emphasizes on causative factors are needed. These are the conclusions from a recent questionnaire study among dentists in Iceland.
Residual stress in bench- and furnace-cooled porcelain-fused to zirconia appliances- A new study of veneered zirconia shows that the magnitude of residual stresses can only be estimated reliably from the manufacturers’ thermal expansion coefficients if the veneered prosthesis is cooled slowly after the final firing.
How can dental materials be made better?- Future resin-based dental materials must combat the reasons current materials fail, mainly secondary caries and fracture, but still be easy for the dentist to use and safe for the patient.

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.
Thermal induced deflection of a porcelain–zirconia bilayer: Influence of cooling rate- To determine the thermal expansion of a porcelain (VM9) and tetragonal zirconia (Y-TZP) as well as the deflection upon re-heating and cooling of a bilayer fabricated from these two materials after slow and rapid cooling during initial fabrication.
