<p>Apparatus and method for external medical treatment of the oral cavity with the aid of light. The apparatus includes a light-emitting device (1), which is intended to be held against or in the close proximity of the patient's body, and means (8, 9, 10) for driving the light-emitting device. The light-emitting device includes light-emitting diodes (3, 4) or corresponding elements adapted to emit infrared (IR) light. The drive means (8, 9, 10) includes a computer (8) and circuits (9, 10) for driving the light-emitting diodes (3, 4), wherein the computer (8) is adapted to deliver electric signals to the drive circuits (9, 10). The drive means (8, 9, 10) is adapted to cause the light-emitting device (1) to emit infrared light in accordance with a series of pulse repetition frequencies. First, light that has a pulse repetition frequency of about 7.8 Hz is emitted and 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.</p> |
