The present invention relates to a powder mixture, in particular for the remineralization of teeth, a powder jet device, in particular for application in the field of dentistry, a use of the powder mixture for producing a means for the remineralization of teeth 5 and to a method for the remineralization of teeth, and a use of a powder mixture in a dental apparatus. The powder mixture comprises a deposition powder which is designed to adhere to tooth surfaces.

A nozzle member (14) of a personal care device (10) comprising: a nozzle head (16) positioned at an end of the nozzle member; and an orifice (40) formed in a surface (30) of the nozzle head, wherein the orifice comprises at least one liquid jet orifice (42) configured to allow the liquid and/or air to exit the nozzle head in the form of a jet, and at least one liquid sheet orifice (40a-d) configured to allow the liquid and/or air to exit the nozzle head in the form of a sheet.

Disclosed are devices, systems and methods for treating periodontal disease and/or other oral wounds using particularized oral appliances and associated negative pressure systems. The various oral appliances include one or a plurality of surfaces for engagement with various anatomical structures within the oral cavity, where the engagement can include sealing engagement with soft tissue (gingival) surfaces of the upper and/or lower dental arches. Additional features disclosed can further promote healing of regions affected by periodontal pocket formation.

A customized oral irrigator which is adapted to the user's dentition, has multiple nozzles or cutout openings to point to the area to irrigate. User can anchor such device by biting with the teeth and irrigate the teeth and gum, especially between the teeth and under the gum, in one instance. Such a device is fast and effective. It will be beneficial to everyone but will especially benefit busy professionals, children, seniors, handicapped, disabled, and other users who have difficulty cleaning teeth, for example people who wear dental devices such as braces. This device is meant to combine oral care procedures such as tooth brushing and dental flossing in one instance and will yield better dental hygiene and with better compliance than conventional brushing and flossing and conventional single channel oral irrigators.

An oral cleansing device including a base and a tip holder configured to hold a tip for the oral cleansing device, such as a brush head, a jet tip, or a combination tip. The tip holder may be removably coupled to the base.

A method for automatically initiating a dental handpiece waterline flushing mode in a dental delivery system comprises detecting whether at least first and second handpiece waterlines from a plurality of handpiece waterlines are removed from respective first and second rest positions of a control head for the dental delivery system. According to some implementations, if it is determined that no additional dental handpiece waterline which is flushable remains in a rest position of the control head, then the dental handpiece waterline flushing mode is automatically initiated for the first and second dental handpiece waterlines. In some implementations, a display is updated to provide information to a user, and an input from the user is received to begin flushing.

The present invention relates to a fluid based tooth cleaning system (10) comprising a holdable body (20), a fluid delivery unit (30), at least one sensor (40) and a control unit (50). The holdable body is configured to be coupled to a head (60). The fluid delivery unit (30) is configured to be coupled to a nozzle (80) configured to emit fluid, and the nozzle (80) is comprised within the head (60). The at least one sensor (40) is configured to provide information, including velocity information, relating to the head (60) with respect to a user's teeth. The at least one sensor (40) is configured to provide the information to the control unit (50). The control unit (50) is configured utilize the information to enable the fluid delivery unit (30) to emit fluid from the nozzle (80) onto the user's teeth.

An electronic impression tray can be used to obtain three-dimensional and temporal measurements in dentistry. There is a device having optical measurement sensor system, and an electronic system including a central management unit capable of collecting, storing and ordering the data obtained by the sensor systems distributed over all or part of the impression tray. An optical impression of all or part of a dental arch can be obtained with a single or multiple impressions. The tray includes a part having the shape of all or part of a dental arch, and the part can change by virtue of its ability to deform and/or a structure formed by multiple elements that are hinged to one another and/or reversibly assembled and secured to one another, such as to provide the optimal shape.

An oral cleansing device including a handle, a brush head removably connected to the handle at a top end of the handle, a base unit that supports a reservoir to serve as a fluid source, a fluid tube extending from the base unit, and a fluid connector connected to the fluid tube and removably connected to the handle at a bottom end of the hand to connect the handle to the fluid source. The fluid connector includes a magnetic element configured to provide a magnetic attraction to the base unit, thereby assisting in securing the fluid connector to the base unit.
