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: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
