Snus and pregnancy – a risky connection
Swedish smokeless tobacco, also known as “snus” is popular in the Nordic countries. It is not without risk, however, and during pregnancy the risks are worth knowing.
Resin-based cements – properties affecting clinical success of indirect restorations
Many clinicians prefer polymer-based, also known as resin-based, cements, when cementing indirect restorations. Especially when the restorations are made of all ceramic materials. A recent paper looks into cement properties that affect clinical success of indirect restorations.
NIOM involved in study for alternative antibacterial methods
The World Health Organization (WHO) has called for the development of alternative antibacterial methods. In response to this, a team involving three NIOM scientists have investigated endogenous compounds and biopolymers.
Genes a factor in fighting dental erosion
Erosive tooth wear is a growing problem. While the causes are many, from increased consumption of soda and acidic food, we now know that genes play a role too. A recent NIOM study looks delves into the subject matter.
Cobalt in dental devices
The use of cobalt in dental devices as crowns, bridges and removable partial prosthesis have now raised concern as cobalt is classified as a CMR (Carcinogenic, Mutagenic, toxic to Reproduction) substance, says Jon E. Dahl, CEO at NIOM.
Effect of Chlorhexidine digluconate on endodontic sealers
A recent study showed increased antimicrobial activity of three endodontic sealers after chlorhexidine contact. Cell toxicity and physicochemical properties were mostly negatively affected.

Presence of 6PPD-quinone in runoff water samples from Norway using a new LC–MS/MS method
The chemical 6PPD-quinone is highly toxic to some fish species of the Oncorhynchus and Salvelinus genera and is the oxidation product of the common car tire additive 6PPD. We present a new sample preparation method that involves liquid-liquid...
Silver release from dentine treated with combinations of silver diamine fluoride, potassium iodide and etching
For individuals with very high to extremely high caries activity and poor control of daily oral hygiene, a simple treatment for arresting their caries activity is necessary. Silver Diamine Fluoride (SDF) has become increasingly common for this purpose due to its...
Preparation of a fluorinated dental resin system and its anti-adhesive properties against S. mutans
Resin system prepared exclusively with fluorinated methacrylate monomers reduced the S. mutans adhesion due to their increased hydrophobicity and decreased surface energy. Compared with Bis-GMA/TEGDMA, the FDMA/FBMA resin system also exhibited higher double bond conversion and lower water sorption and solubility

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.
