According to a study in the September/October issue of General Dentistry, the Academy of General Dentistry’s (AGD) clinical, peer-reviewed journal, halitosis is a term used to describe any disagreeable odor of expired air. Bad breath is a generally accepted term for foul smells emanating from the mouth. Oral malodor is a term reserved for unpleasant smells originating from the oral cavity. “A common reason for bad breath is post-nasal drip, which coats the back area of the tongue with bacteria-rich mucous,” says AGD spokesperson, June Lee, DDS, MAGD. “A tongue scraper is often effective in relieving oral malodor caused by sinus drainage.”
The study reviewed literature examining the effects of using tongue scrapers to brush the tongue, rather than using a toothbrush to scrape the tongue. Data revealed that a tongue cleaner/scraper demonstrated a significant difference in reducing volatile sulfur compounds (VSC) levels, which are produced when bacteria and amino acids interact to produce bad breath.
Though there is no standard treatment, bacteria-causing halitosis can be reduced by brushing or scraping the middle and back of the tongue. Tongue scraping can lower VSC concentration, subsequently reducing oral malodor. However, that reduction is only short-term, and not an absolute solution for eliminating malodor. The authors of the General Dentistry article feel that future research is necessary to determine what role undetected odorants may play in oral malodor, as well as more well designed, randomized clinical trials to compare the effectiveness of tongue scrapers, toothbrushes, and mouth rinses on reducing VSC levels.
Despite the short-term reduction, Dr. Lee feels that tongue scrapers are a good tool for the short-term. “Tongue cleaners and scrapers are straightforward and comfortable to use, easy to transport, and inexpensively priced. Cleaning the tongue is quickly and easily accomplished. Everyone from children to elders should be able to incorporate this technique into their oral care regimen.”
Bad breath basics:
• Halitosis is a general term used to describe any disagreeable odor of expired air, regardless of its origin.
• Bad breath is a generally accepted term for foul smells emanating from the mouth.
• Oral malodor is a term reserved for halitosis originating from the oral cavity.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
