A tooth cleaning system includes a handheld toothbrush portion coupled by tubes to an arm-mounted module. Collectively, the handheld toothbrush portion and the arm-mounted module include an oscillating toothbrush head; an irrigation system having a pump, reservoir, and tubing; and a scavenge system having a pump, reservoir, and tubing. In some examples, portions of the irrigation system are disposed in the handheld toothbrush and portions of the irrigation system are disposed in the arm-mounted module.

An apparatus for treatment of teeth, including one or more dental treatment applicators having at least two walls and a floor, the walls and floor defining a well configured to accommodate at least one human dental arcade and an active agent. Furthermore, one or more energy-applying elements such as electrodes or light sources are located on at least one of the walls.

An electrical discharge irrigation device and method is described. An electrical discharge irrigation device includes a power source, a circuit coupled to the power source, and an output tip coupled to the circuit. The output tip includes a first end and a second end and a longitudinal axis extending between them, an electrode located in an interior space of the output tip configured to receive an electrical charge from the circuit and to release an electric discharge, and a ground return including an inner surface of the output tip, wherein a space between the electrode and the ground return comprises a conductive medium, the conductive medium being in contact with the electrode and the ground return to produce the electric discharge.

A new method and a system for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The device includes a dispensing unit for the composition, a distal end of which is adapted to apply the composition onto teeth or gums. The device further includes an electrode system having first and second electrodes, the first electrode adapted to be held against the composition at a location at or near teeth or gums, and the second electrode adapted to be held against the composition at a location away from teeth or gums. The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the first and second electrodes.

The invention relates to a hand-held device for excitation and irradiation of pathogenic microorganisms in the mouth and throat, e.g. a toothbrush comprising at least one excitation light source in the short-wave visible spectral range for auto-fluorescence excitation of the pathogenic microorganisms, at least one primary irradiation light source in the red spectral range for primary irradiation of the pathogenic microorganisms and for transillumination, and optionally at least one secondary irradiation light source in the visible spectral range for secondary irradiation of the pathogenic microorganisms, wherein the irradiation light sources have spectral components that can be absorbed by endogenous porphyrins, which are produced by the pathogenic microorganisms, whereby a fluorescence excitation and an inactivation of the pathogenic microorganisms occurs on the basis of subsequent processes. In order to prevent the unintentional irradiation of the eyes, a pressure sensor is designed to release higher light intensities only once a contact pressure has been measured. In addition, the radiation must leave the hand-held device in a divergent manner. The spatially resolved detection of the fluorescence of the pathogenic microorganisms can optionally be used to induce the inactivation of the bacteria by targeted irradiation in the fluorescent range.
