MOUTHPIECE-SHAPED LED IRRADIATION DEVICE FOR WHITENING

摘要

PROBLEM TO BE SOLVED: To provide a safe and comfortable whitening device which suppresses heat generation in teeth and gum and improves whitening light enhancement.;SOLUTION: A mouthpiece-shaped LED irradiation device for whitening comprises: a mouthpiece-shaped irradiator that includes a metal cavity 3 which can be filled with an aqueous soft gel transmitting light and heat and can reflect light inside, and has high heat conductivity, and that irradiates a tooth surface with an LED in the cavity; a cooling mechanism 7 that is in contact with the mouthpiece-shaped irradiator with high heat conductivity, and that cools teeth, gum, the aqueous gel, and LED elements 1 located in the cavity; a control system for controlling the LEDs so that they are not illuminated when a detected temperature of the mouthpiece-shaped irradiator exceeds a preset temperature, and stopping cooling or outputting a warning when the detected temperature is outside a preset upper/lower limit temperature; a cavity cover including an opening covering the metal cavity, having non-heat conductivity, high cushioning property, and not transmitting or absorbing light, and capable of restricting light irradiation in the opening area; and a mouthpiece cover covering the whole mouthpiece, and made of a stretch film having light transparency.;COPYRIGHT: (C)2016,JPO&INPIT
