Abstract:
Apparatus for external medical treatment of the oral cavity with the aid of light, said apparatus comprising: a light-emitting device to be held in close proximity of a patient's oral cavity, wherein the light-emitting device includes light-emitting elements that emit monochromatic light, means for driving the light-emitting device wherein the drive means drives the light-emitting device to emit at least one type of monochromatic light over at least one predetermined time period and to pulsate the light emitted in accordance with a predetermined series of pulse frequencies over said at least one time period, wherein said drive means includes a computer and circuits for driving the light-emitting diodes, wherein the computer is adapted to deliver electric signals to the drive circuits so that the light-emitting diodes emit infrared light within predetermined time periods and at predetermined pulse repetition frequencies, wherein the light emitting device is placed against the patient's cheek, and the drive means drives the light-emitting device to emit solely infrared (IR) light in accordance with a series of pulse repetition frequencies, wherein light that has a pulse repetition frequency of about 7.8 Hz is emitted first and is followed by light that has a pulse repetition frequency of about 287 Hz, which is followed by light that has a pulse repetition frequency of about 31.2 Hz.
