  • Patent number: 8801763
    Abstract: The appliance includes a brushhead having conductive fiber bristles by which a potential is applied to electrochemically activate a teeth whitening substance, such as peroxide, in the vicinity of the teeth. An impedance appliance system (62) or an optical appliance system (27) provides information concerning whether the conductive fiber bristles are adjacent a tooth surface or gum region. The impedance system uses an electrical signal through the fiber to determine the impedance of a circuit which includes the tooth or gum surface, the impedance being different, depending on whether a tooth or gum surface is in the circuit. The optical system generates a light beam which is directed to the mouth surface through a conductive fiber, the color of the returning light indicating whether the surface is a tooth or gum region. If a tooth is determined, the teeth whitening substance is activated at that bristle, while if gum tissue is determined, the teeth whitening substance is not activated at that bristle.

  • Patent number: 5997530
    Abstract: Cryogen spray cooling of skin surface with millisecond cryogen spurts is an effective method for establishing a controlled temperature distribution in tissue and protecting the epidermis from nonspecific thermal injury during laser mediated dermatological procedures. Control of humidity level, spraying distance and cryogen boiling point is material to the resulting surface temperature. Decreasing the ambient humidity level results in less ice formation on the skin surface without altering the surface temperature during the cryogen spurt. For a particular delivery nozzle, increasing the spraying distance to 85 millimeters lowers the surface temperature. The methodology comprises establishing a controlled humidity level in the theater of operation of the irradiation site of the biological tissues before and/or during the cryogenic spray cooling of the biological tissue. At cold temperatures calibration was achieved by mounting a thermistor on a thermoelectric cooler.
