Peroxide-free tooth whitening

The peroxide-free tooth whitening products are less effective than those based on peroxides and the effect is only transitory. Both peroxide-free and peroxide containing products gave an initial lightening of the tooth color. However, the effects of peroxide-free products were only transitory.

Dementia. Are dentists protected?

Dementia is a common term for diseases of the brain expressed as the loss of cognitive abilities and activities of daily living. The number of persons with dementia is increasing due to the aging population in the developed countries, and the risk of dementia is higher in the very old age groups.

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.
