Apparatus and a method for external medical treatment of the oral cavity with the aid of light. A light-emitting device is held against or in the close proximity to a patient's cheek. The device includes light-emitting diodes or corresponding elements that emit infrared (IR) light. A drive arrangement includes a computer and circuits for driving the light-emitting diodes, wherein the computer delivers electric signals to the drive circuits. The drive arrangement causes the light-emitting device to emit infrared light in accordance with a series of pulse repetition frequencies of about 7.8 Hz, 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. |
