Definitions
- the present invention relates to an electric toothbrush with integrated LED light source to transmitting light for photodynamic therapy and many other photo initiated treatments.
- Photodynamic therapy can be applied in mouth, with light transmitting between the electric tooth brush handle and the brush tip.
- Photodynamic therapy is a medical treatment that utilizes a photosensitizing molecule (frequently a drug that becomes activated by light exposure) and a light source to activate the administered drug.
- the procedure is easily performed in a physician's office or outpatient setting.
- PDT is currently used in numbers of medical fields, including oncology (cancer), dermatology (skin), cosmetic surgery, ophthalmology, surgery, edema therapy and oral medicine.
- Photodynamic therapy has roots going to ancient Egypt and Hellenistic civilizations. People noticed the curing ability of sun light for skin diseases. During 19. Century some treatment methods used as using sun light passing behind the red colored window glasses before washing the patient skin.
- PDT essentially has three steps. First, a light-sensitizing liquid, cream, or intravenous drug (photosensitizer) is applied or administered. Occasionally, a photosensitizing molecule that is already part of the body can be activated. Second, there is an incubation period of minutes to days. Finally, the target tissue is then exposed to a specific wavelength of light that then activates the photosensitizing medication. The mechanism by which tissue is destroyed seems to depend on the presence of activated oxygen molecules. Although first used in the early 1900s, PDT in the modern sense is a new, evolving science. Current PDT involves a variety of incubation times for different the light- sensitizing drugs and a variety of light sources depending on the target. The basic premise of PDT is selective destruction. The generation of singlet oxygen species by type II photochemical reactions is believed to be the predominant reaction in PDT. At low levels of PDT, biological systems may be positively stimulated by low enhancement of ROS levels.
- PDT light sources include laser light, intense pulsed light, light-emitting diodes (LEDs), blue light, red light, and many other visible lights (including natural sunlight).
- Photosensitizer drugs may become activated by one or several types of light.
- the optimal light source depends on the ideal wavelength for the particular drug used and target.
- Electric toothbrush has rapid, automatic bristle motions, either back-and-forth oscillation or rotation-oscillation (where the brush head alternates clockwise and counterclockwise rotation), in order to clean teeth.

Description
ELECTRIC TOOTHBRUSH WITH INTEGRATED LED LIGHT SOURCE Field of the invention
The present invention relates to an electric toothbrush with integrated LED light source to transmitting light for photodynamic therapy and many other photo initiated treatments. Photodynamic therapy can be applied in mouth, with light transmitting between the electric tooth brush handle and the brush tip.
Background of the invention
Photodynamic therapy (PDT) is a medical treatment that utilizes a photosensitizing molecule (frequently a drug that becomes activated by light exposure) and a light source to activate the administered drug. The procedure is easily performed in a physician's office or outpatient setting. PDT is currently used in numbers of medical fields, including oncology (cancer), dermatology (skin), cosmetic surgery, ophthalmology, surgery, edema therapy and oral medicine.
Photodynamic therapy has roots going to ancient Egypt and Hellenistic civilizations. People noticed the curing ability of sun light for skin diseases. During 19. Century some treatment methods used as using sun light passing behind the red colored window glasses before washing the patient skin.
The principle of photodynamic action was first described by Oscar Raab in 1890 when he noted the toxic effects of acridine orange, which showed activity as a photosensitizer when combined with light and oxygen by destroying Paramecium caudatum cells without apparent damage to the protozoa when used alone. Von Tappeiner discovered in 1903 that the administration of eosin following irradiation with light led to oxygen-dependent tissue reactions and improvements in skin diseases such as condylomata lata, lupus vulgaris, psoriasis, syphilis, and skin
cancers. He termed this activity a "photodynamic reaction". In the late 1970s, photodynamic therapy (PDT) with hematoporphyrin derivative (HPD) was developed by Thomas Dougherty and his co-workers. They purified HPD to some extent and discovered that the administration of HPD followed by irradiation with red light resulted in oxygen-dependent tissue reactions.
PDT essentially has three steps. First, a light-sensitizing liquid, cream, or intravenous drug (photosensitizer) is applied or administered. Occasionally, a photosensitizing molecule that is already part of the body can be activated. Second, there is an incubation period of minutes to days. Finally, the target tissue is then exposed to a specific wavelength of light that then activates the photosensitizing medication. The mechanism by which tissue is destroyed seems to depend on the presence of activated oxygen molecules. Although first used in the early 1900s, PDT in the modern sense is a new, evolving science. Current PDT involves a variety of incubation times for different the light- sensitizing drugs and a variety of light sources depending on the target. The basic premise of PDT is selective destruction. The generation of singlet oxygen species by type II photochemical reactions is believed to be the predominant reaction in PDT. At low levels of PDT, biological systems may be positively stimulated by low enhancement of ROS levels.
PDT light sources include laser light, intense pulsed light, light-emitting diodes (LEDs), blue light, red light, and many other visible lights (including natural sunlight). Photosensitizer drugs may become activated by one or several types of light. The optimal light source depends on the ideal wavelength for the particular drug used and target. Electric toothbrush has rapid, automatic bristle motions, either back-and-forth oscillation or rotation-oscillation (where the brush head alternates clockwise and counterclockwise rotation), in order to clean teeth. Motions at sonic speeds or below
are made by a motor. In the case of ultrasonic toothbrushes, ultrasonic motions are produced by a piezoelectric crystal. A modern electric toothbrush is usually powered by a rechargeable battery charged through inductive charging when the brush sits in the charging base between uses.
The first electric toothbrush was introduced in the early 1960s, as cordless with rechargeable NiCad batteries and although portable, was rather bulky, about the size of a two-D-cell flashlight handle. NiCad batteries of this period suffered from the Memory effect. The GE Automatic Toothbrush came with a charging stand which held the hand piece upright; most units were kept in the charger, which is not the best way to get maximum service life from a NiCad battery. Also, early NiCad batteries tended to have a short lifespan. The batteries were sealed inside the GE device, and the whole unit had to be discarded when the batteries failed. The use of an AC line voltage appliance in a bathroom environment was problematic. By the early 1990s Underwriter Laboratories (UL) and Canadian Standards Association (CSA) no longer certified line-voltage appliances for bathroom use. Newer appliances had to use a step-down transformer to operate the actual toothbrush at low voltage (typically 12, 16 or 24 volts). Wiring standards in many countries require that outlets in bath areas must be protected by a RCD/GFCI device (e.g., required in USA since the 1970s on bathroom outlets in new construction).
By the 1990s there were problems with safety certification of Broxo's original design. Further, improved battery-operated toothbrushes were providing formidable competition.
The first ultrasonic toothbrush, first called the Ultima and later the Ultrasonex, was patented in the U.S. in 1992, the same year the FDA gave it approval for daily home use. Initially, the Ultima worked only on ultrasound, but a few years later, a motor was added to give the Ultrasonex brush additional sonic vibration. Today, several ultrasonic toothbrushes simultaneously provide both ultrasound and sonic vibration.
In more modern times, electric toothbrushes have been used as a substitute for vibrators for those that wish to avoid embarrassment
Electric toothbrushes can be classified according to the frequency (speed) of their movements as power, sonic or ultrasonic toothbrushes, depending on whether they make movements that are below, in or above the audible range (20-20,000 Hz or 2400-2,400,000 movements per minute), respectively.
The United States document numbered US2016331121 discloses a toothbrush having a body and a treatment device is disclosed. The toothbrush comprises: a body comprising a handle portion, a head portion and a longitudinal axis; a plurality of tooth cleaning elements extending from the head portion; a treatment device coupled to the body so as to be alterable between a storage state and a use state, the treatment device comprising: a housing; a power source disposed within the housing; and an electromagnetic radiation source disposed within the housing and operably coupled to the power source.
In the state of the art, teeth whitening and removal of mouth bacteria is a common goal during modern dental procedures. However, regular treatment is required to effectively remove bacteria and effectively whiten teeth. Traveling to the dentist for regular treatments for teeth treatments can be inconvenient and expensive. One way to effectively treat teeth is to use ultra-violet radiation emitted from a specialized dental instrument available for use at a professional dentist's office. Because of the difficulty of visiting a dentist regularly, many people would prefer to utilize a personal dental instrument and products available for residential use rather than travel to the dentist for regular treatment. In-home self-administered treatments are available for teeth-care. However, in-home dental treatment devices are generally more limited and less effective.
Objects of the invention
The present invention, can achieve an electric or battery-powered toothbrush, which has ability to apply photodynamic therapy and many other photo initiated treatments like tooth bleaching or healing a sore canker with integrated LED light source, during daily usage.
Placing the LEDs with different wavelengths in the same toothbrush, it will be possible to provide both emitting light in the specific wavelength that photodynamic therapy is required and giving an infrared for increasing osteoblastic activity and accelerating the wound healing with the bio- stimulation of the surrounding gingival tissues and many other photo initiated treatments like tooth bleaching or healing a sore canker. Photodynamic therapy can be applied by the patient daily, outside the clinic with the present invention. Therefore, light energy will be accumulated in the oral tissues and the use of appropriate chemical agents, it will be possible to provide continuous oral hygiene for the patients.
