Solar powered teeth cleaning

The toothbrush – which operates with around the same amount of light as a solar powered calculator – creates a solar powered chemical reaction in the mouth. It has a solar panel at its base that transmits electrons to the top of the toothbrush through a lead wire. These electrons react with acid in the mouth which starts a chemical reaction that can break down plaque and kill bacteria, eliminating the need for toothpaste.

The toothbrush has already been tested in cultures of bacteria that cause periodontal disease and inventor, Dr Kunio Komiyama said: “The brush causes complete destruction of bacterial cells.”

Komiyama – a dentistry professor emeritus at the University of Saskatchewan – first had the idea for a solar powered toothbrush 15 years ago. Together with his colleague Dr Gerry Uswak, he has developed his latest version, the Soladay-J3X, which will be manufactured by the Shiken company of Japan.

The pair is planning to recruit 120 teenagers to test the toothbrush to see how it compares to a normal manual brush. It has already won first prize at the FDI Annual World Dental Conference in Dubai.

Angelina Jolie (born Angelina Jolie Voight; June 4, 1975) is an American actress. She has received an Academy Award, two Screen Actors Guild Awards, and three Golden Globe Awards. Jolie promotes humanitarian causes, and is noted for her work with refugees as a Goodwill Ambassador for the United Nations High Commissioner for Refugees (UNHCR).

Though she made her screen debut as a child alongside her father Jon Voight in the 1982 film Lookin' to Get Out, Jolie's acting career began in earnest a decade later with the low-budget production Cyborg 2 (1993). Her first leading role in a major film was in Hackers (1995). She starred in the critically acclaimed biographical films George Wallace (1997) and Gia (1998), and won an Academy Award for Best Supporting Actress for her performance in the drama Girl, Interrupted (1999). Jolie achieved wider fame after her portrayal of video game heroine Lara Croft in Lara Croft: Tomb Raider (2001), and since then has established herself as one of the best-known and highest-paid actresses in Hollywood.[7] She has had her biggest commercial successes with the action-comedy Mr. & Mrs. Smith (2005) and the animated film Kung Fu Panda (2008).[8]

Divorced from actors Jonny Lee Miller and Billy Bob Thornton, Jolie currently lives with actor Brad Pitt, in a relationship that has attracted worldwide media attention. Jolie and Pitt have three adopted children, Maddox, Pax, and Zahara, as well as three biological children, Shiloh, Knox, and Vivienne.
