Myth that snuff users today have fewer dental caries

23.11.2012
It is a myth that snus (Swedish snuff) users today have fewer dental caries. On the contrary, some types of nicotine-free snus contain both carbohydrates and starch that increase the risk of cavities. Those are the findings of a thesis from Sahlgrenska Academy, University of Gothenburg, Sweden.
A common notion is that people who use nicotine-containing snus have fewer cavities. But that notion is a myth. A fact proven by Lena Hellqvist, a doctoral student at Sahlgrenska Academy, University of Gothenburg and a member of staff at Karlstad University, who studied oral health among snus users for her thesis.

"Normal Swedish snus containing nicotine is alkaline and therefore raises oral pH levels, which could have a beneficial effect against acid attacks. However, there was no clinical confirmation during our studies that snus users have fewer caries today," says Lena Hellqvist.

"On the other hand, neither do snus users have more caries, which may be partially explained by the general improvement in oral health in Sweden and daily use of fluoride toothpastes. It is clear though that tobacco users visit the dentist and clean their teeth less often than non-users."

People who use nicotine-free snus products also have reason to be watchful. Lena Hellqvist's thesis reveals that while nicotine-containing snus only contains traces of carbohydrates and starch, nicotine-free snus can contain up to 26 per cent starch and 6.5 per cent carbohydrates.

"Our figures showed that some nicotine-free snus products considerably reduced users' plaque pH. Together with the high carbohydrate content, this means that use of nicotine-free snus can increase the risk of caries," says Lena Hellqvist, who emphasises that the results only concern the products included in the study in question, and not necessarily all products available on the market.

The thesis also shows that tobacco use generally has fallen over the past 20 years, but that the number of snus users has increased in the same period – data supported by several other national studies.
The thesis also reveals that tobacco use is more common among single men than among men with a partner. There is no difference however when it comes to level of education or income.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
