Are LED Lights a Hazard to Human Health?

There is no evidence that the general public is at risk of direct adverse health effects from Light Emitting Diodes (LEDs) when the lights (lamps for lighting and displays) are in normal use, the European Commission stated in a recent published Opinion. The Scienti c Committee on Health, Environmental and Emerging Risks (SCHEER), having a NIOM scientist as expert member, authored the Opinion.

Digital evaluation of marginal and internal fit of single-crown fixed dental prostheses

The adaptation of single-crown fixed dental prostheses (FDPs) is a subject of great interest in the research community. Many investigations have been published, and a variety of evaluation methods have been used to determine the fit accuracy of prosthetics.
Many of the methods required manual measurements of the gap between the restoration and the abutment. With the introduction of CAD/CAM techniques, digital tools started being used for evaluating the adaptation of FDPs.
In this study, a tabletop dental scanner was used. It is anticipated that in a clinical setting, an intraoral scanner is sufficient, at least for single-crown FDPs.

Biofilms and their properties

Oral biofilm‐associated diseases, such as caries and periodontitis, represent global public health challenges. The diseases develop as a result of dysbiosis of the oral microbiome. There is a long tradition in medicine for treating bacterial infections by the use of antibiotics. Unfortunately, biofilm bacteria are significantly less sensitive to antibacterial agents than are their planktonic counterparts. This property of biofilm challenges us in our daily work as dentists, and might explain why many oral prophylactic agents predicted to be efficacious in vitro, only show marginal effect in vivo.

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.
