Abstract: An oral treatment device comprises a head for use in treating an oral cavity of a user, the oral cavity comprising a plurality of oral cavity zones, and an inertial measurement unit, IMU, operable to output signals dependent on position and/or movement of the head. The oral treatment device comprises a controller configured to receive signals from the IMU indicating position and/or movement of the head relative to the oral cavity, and process the received signals using a trained non-linear classification algorithm to obtain classification data. The classification algorithm is trained to identify, from the plurality of oral cavity zones, an oral cavity zone in which the head of the oral treatment device is located. The controller is configured to control the oral treatment device to perform an action using the obtained classification data.

Abstract: An oral treatment device is provided. The oral treatment device comprises an inertial measurement unit, IMU, operable to output signals dependent on position and/or movement of the oral treatment device. The oral treatment device comprises a fluid delivery system for delivering working fluid to an oral cavity of a user. The oral treatment device comprises a controller configured to process signals received from the IMU indicating position and/or movement of the oral treatment device relative to the oral cavity of the user, and on the basis of the processing, output a control signal to the fluid delivery system to control delivery of the working fluid.

Abstract: A subgingival cleaning system (10) for cleaning a subgingival region such as a periodontal pocket is disclosed. The system comprises a liquid flow source (60) for producing a liquid flow and a gas flow source (70) for producing a gas flow. Each of the liquid flow source and the gas flow source are coupled to a nozzle arrangement (40) arranged to be aimed at a subgingival region to be cleaned, the nozzle arrangement comprising at least one nozzle (41, 42, 43). The system is configured to produce a fluid stream comprising a series of liquid pulses from said liquid flow source, said liquid pulses each having a duration of 5-100 ms, preferably 8-40 ms, with an interval of 1-50 ms, preferably 2-10 ms, between subsequent liquid pulses; and a gas flow from said gas flow source at least partially filling said intervals. Also disclosed is a nozzle arrangement for forming such a subgingival cleaning system.

Abstract: An apparatus for fluid delivery in oral irrigation comprises a fluid delivery tube with a proximal end and a distal end. The proximal end is configured to receive fluid for oral irrigation. A nozzle is placed at the distal end of the fluid delivery system and a mechanical valve is placed at the nozzle. The mechanical valve is closed in equilibrium and is configured to open when a force is applied to the mechanical valve by each of two neighboring teeth.

Abstract: The present disclosure relates generally to oral health products, such as electric toothbrushes. In one example, the electric toothbrush includes a housing, an output shaft positioned within and extending out of the housing, a magnetic assembly positioned within the housing and configured to impart an oscillation motion to the output shaft, and a spring positioned within the housing. The spring includes a first end non-rotatably coupled to the housing and a second end non-rotatably coupled to the output shaft, such that the spring twists as the magnetic assembly oscillates the output shaft to amplify the oscillation motion of the output shaft generated by the magnetic assembly.

Abstract: Ultrasonic cleaning methods may be enhanced by adding certain particles to a liquid through which ultrasonic waves travel through. Specifically, metal nitrites, metal carbides, and metal oxide particles may be used separately or together, to enhance the cleaning effect. When such nanoparticles are added to a liquid medium, and ultrasonic sound waves propagate therethrough, cavitation bubbles form producing high forces on contaminates which adhere to the object being cleaned. The nanoparticles are carried by microjets on the surface of the object, and further aid in disinfecting and sterilizing the object's surface.
