New "massage method" quadruples protection against tooth decay

26.03.2012
Do you really want to avoid cavities in your teeth? Try massaging them with a high-fluoride toothpaste after lunch.

“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
Researchers at the University of Gothenburg’s Sahlgrenska Academy have now performed the first scientific evaluation of the effect of this so called “high-fluoride toothpaste”. The study has resulted in a new method that quadruples the level of protection from fluoride.
Four times better protection
In the study, 16 volunteers tested a variety of brushing techniques, using either high-fluoride or standard toothpaste, and brushing either two or three times a day.

“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
Also tested was a new method developed in collaboration with professor Dowen Birkhed, which involves rubbing toothpaste onto your teeth with a finger.

“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.”

Daily use is essential
Brushing with fluoride toothpaste has played – and continues to play – a major role in combating tooth decay, and there is strong scientific evidence that daily use of fluoride toothpaste has a pronounced preventive effect.

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.

THE RESEARCHER´S TOP TIPS
• Use toothpaste at least twice a day, after breakfast and before going to bed.
• If necessary, brush a third time or rub on some toothpaste instead.
• If you have problems with cavities, choose a toothpaste with a higher fluoride content.

• Avoid rinsing out the toothpaste with water.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
