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: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

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...

Im Focus: Designing Architecture with Solar Building Envelopes

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...
