Abstract
A method of using a heat sink device with an intraoral illumination device includes inserting an intraoral illumination device at least partially in a patient's mouth, connecting a heat sink device to the intraoral illumination device, the heat sink device including an illumination device that emits light and heat when activated and a heat sink member thermally coupled to the illumination device; activating the illumination device so that light is transmitted to the intraoral illumination device and into the patient's mouth, aspirating fluid from the patient's mouth at negative pressure; and causing aspirated fluid to flow past the heat sink member at negative pressure so that heat is removed from the heat sink member, causing the illumination device to be cooled.
