“Rubbing toothpaste onto your teeth increases the fluoride protection by 400%,” says Anna Nordström, dentist, PhD and researcher at the Sahlgrenska Academy at the University of Gothenburg, Sweden.
Eight years ago a new brand of toothpaste was launched in Sweden with more than three times as much fluoride as standard toothpaste. Available without prescription, it is aimed primarily at those with high caries risk.First scientific evaluation
“The study revealed that those who used a high-fluoride toothpaste three times a day had four times better fluoride protection in the mouth than those who used standard toothpaste twice a day,” says researcher Anna Nordström from the Institute of Odontology at the Sahlgrenska Academy.Rub your teeths after lunch
“This ‘massage’ method proved to be at least as effective as a third brushing in increasing the amount of fluoride in the mouth,” Anna Nordström explains. “Rubbing the front of your teeth with toothpaste can be an easy way of giving your teeth a third “shot” of fluoride during the day, after lunch for example. But this should not replace brushing with a fluoride toothpaste morning and evening – it’s an extra.”
The study Effect of a third application of toothpaste (1450 and 5000 ppm F), including a “massage” method, on fluoride retention and pH drop in plaque was published in Acta Odontologica Scandinavia.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

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...
