Is blue light damaging to our skin?

Blue light beams at us during procedures at the clinic, from the screens we watch between patients, and from our ever present mobile phones. Recently we have seen cosmetic companies selling creams marketed towards blue-light damage. But can blue light really damage the skin, and if so- how?

Lack of training hinders best practice

While stainless-steel crowns (SSCs) are recommended for restorative treatment of teeth severely affected by caries, fractures or dental developmental disorders, they are not widely used. A new NIOM study among Norwegian and Finnish dentists explores why.

New teeth- straight from the lab?

The dental community has long been fascinated by the thought of growing a third set of teeth. According to Nils Jacobsen and colleagues’ recent overview article on the subject, the past 40 years of research has seen great strides towards this goal. There have been several key breakthroughs, based heavily on knowledge acquired in stem cell research.

Erosive tooth wear: Young men at risk

Young men are most at risk as carbonated soft drinks wear down young adult’s teeth. In a new questionnaire-based study performed in Denmark, almost all the respondents blamed erosive tooth wear in young adults on carbonated soft drinks.

Pre-cementation procedures’ effect on dental zirconias with different yttria content

Several pre-cementation procedures have been advocated to enhance adhesion between zirconia and resin-based cement. There is, however, limited documentation on how these pre-treatments affect the strength of zirconia crowns as most tests are performed on discs or bars.
The aim was to assess the effect of pre-cementation procedures on fracture mode, fracture strength and cement retention on zirconia.

Genetic Aspects of Dental Erosive Wear and Dental Caries (Review Article)

The present review aims to give an overview of the literature focusing on novel genetic aspects of dental erosion and dental caries. Once the tooth erupts into the oral cavity, the regenerative capability of enamel is fundamentally limited due to the loss of dental epithelium during eruption. The susceptibility or resistance to dental erosion and caries is presumably a result of environmental, phenotypic, and/or genetic influence. Even though it is evident that individuals frequently exposing their teeth to acid and sugar are at high risk of developing dental erosion and caries, the findings exclusively based on these factors are elusive.

Survival of primary molars with pulpotomy interventions: public oral health practice-based study in Helsinki

The study concludes: “The estimated survival time of pulpotomized primary molars is affected by dental operator- related factors, which should be considered in management of extensively carious primary molars of paediatric patients, both at the clinical and organizational decision-making levels. An increased focus on the use of SSC is recommended to be in the learning objectives of dental education programs.

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.
