A promising news in The Nikkei Business Daily
While Beldente was under development, the following article was published in The Nikkei Business Daily on April 6, 2005. The title was “Blue Light has effect on the gingivitis treatment”.
Blue light has effect on the gingivitis treatment
Researchers at Boston-based Forsyth Institute discovered that seconds of blue light irradiation was effective for prevention and treatment of periodontal disease. It may lead to a new treatment with quick effect and less stress in patients.
A few seconds of light radiation can effectively kill bacteria. The effect also has been confirmed through experiments using dental plaque of patients with a gum disease.
Background story of Beldente, the world’s first LED toothbrush
- Researchers found that seconds of blue light(380～520nm wavelength) irradiation was effective for prevention and treatment of gum diseases such as periodontitis.（*1）。
- Doctors also announced that the 405nm visible light was sufficient to inhibit growth of Porphyromonas gingivalis.（*2）。
- Researchers confirmed that LED light inhibited Porphyromonas gingival through their experiments requested by Toyo Living.（*3）。
Beldente, a practical LED lighting toothbrush has been completed based on the above findings and results. It features a 400～520nm wavelength LED light centered on the brush head. The light irradiation and brushing will work synergistically to prevent gum diseases.
This is the background story of Beldente(“Beautiful teeth” in Italian).

Beldente is a LED toothbrush born from an innovative idea.
People can confirm their teeth and gums, ensure better brushing with the bright safe visible LED light spreading in the mouth. After brushing, you may feel fresher than ever before.
Some studies show that the LED Light inhibits the growth of pathogens that cause periodontal disease.
It may be said that this is one of the innovative features that a conventional toothbrush does not have. We hope it can help you eliminate bacteria and improve your oral health with the bright light.

About BELDENTE
Good dental care is essential to a healthy long life.
If you want to live a healthy life, it is vital to prevent gum diseases. Beldente performs the measures against gum disease by lighting up your mouth, checking and brushing your teeth, and massaging your gum with its tapered fine bristles.
Effects of Beldente's LED light
- Most people are not brushing their teeth completely due to personal habits or spots that a regular brush can not reach. Beldente can light up your mouth to help you brush thoroughly with the bright LED light.
- The result is Beldente that will make your teeth shiny and whitening.
- You may feel more refreshed in your mouth and taste your breakfast better than ever before, with the synergistic effect between irradiation from the brush top and manual brushing.
Shape and style (Registered design)
- Beldente has a space-saving and self standing design, it fits well in your hand. It makes daily oral care much comfortable with the LED light.
- The design is well-balanced. It is light and suitable for people of all ages from children to the elderly.
- Beldente does not make sound and vibration, and you might feel comfortable and relaxing with the soft light, different from electric toothbrushes.
Features of Beldente
- Beldente uses white tip type LED as the source of light, which is very bright, safe and very thin visible light.
(Thickness: 1.2mm, Wavelength: around 400-520nm/ Light intensity: ave.1,350mcd) - Energy-saving, design with zero electric consumption during stand-by time.
- 8-minute automatic shut-off timer.
- Constant voltage circuit.
The brightness of light will remain constant even when the battery voltage is falling.
For approximately 6 months (3 minutes x 3 times/day on one Alkali AA battery). - Fully waterproofed and washable.
- Eco-friendly design with a replaceable brush head.
(The replacement brush head weigh about 1/6 of the whole toothbrush.) - The bristles are tapered and formed uniformly through chemical processing. The surfaces are soft and smooth and can bend and flex into teeth and gum pockets. Moreover, the bristles are made much durable by the addition of PBT resin (Saturated Polyester) and can remain unchanged due to water and moisture absorption.
The most distinctive feature of Beldente
- The big difference between Beldente and current manual or electric toothbrushes is that Beldente’s LED light has inhibitory effect on the pathogen (P.gingivalis) which is experimentally confirmed. It is an innovative idea to apply it to a commodity.
- This will not only benefit people’s oral health but also an even greater goal to prevent lifestyle-related diseases.
