An oral care appliance and a method of use are disclosed. The oral care appliance includes a mouthpiece with one or more enclosed compartments between an outer surface and an inner surface of the mouthpiece. The inner surface comprises at least one flexible membrane surrounding the one or more enclosed compartments. The oral care appliance also includes a control unit configured to regulate pressure variations in the one or more enclosed compartments to deform the flexible membrane and thereby perform an oral care action.

A cleaning device (10) comprising: a body portion (12); a nozzle member (14) mounted on the body portion and comprising a nozzle head (16), wherein the nozzle member is configured to allow passage of liquid and/or air from a reservoir in the body to the nozzle head; and an orifice (40) in the nozzle head configured to allow the liquid and/or air to exit the nozzle head, wherein the orifice is configured to shape the exiting liquid and/or air into at least one liquid sheet having a length greater than a width at a target cleaning distance.

An oral care device for providing oral-cavity information to a user or a manager includes: a liquid supply unit; a mouthpiece connected to the liquid supply unit and including a spatial portion configured to accommodate at least one of an upper tooth side and a lower tooth side when the mouthpiece is inserted into an oral cavity; a pump connected to the mouthpiece and configured to suction liquid from the liquid supply unit and introduce the liquid into the spatial portion and to suction fluid from the spatial portion; a storage unit connected to the pump and configured to store or discharge fluid suctioned from the spatial portion; and a measuring unit connected to the storage unit and configured to measure a state of fluid stored in the storage unit, wherein liquid is introduced to the spatial portion from the liquid supply unit only by suction force of the pump.

Disclosed is a portable teeth cleaning apparatus, which implements, through a pump in a teeth cleaner, a function of supplementing a teeth cleaning liquid from a connecting seat connected to the teeth cleaner. Therefore, it is no longer necessary to connect the teeth cleaner to a teeth cleaning liquid source through a connecting hose during teeth cleaning, and liquid leakage is avoided during liquid supplement. Further, a seating/unseating status and whether a liquid reservoir is filled up are detected automatically, and a controller controls on/off and switching of a series of valves, thereby implementing automatic liquid supplement of the teeth cleaner.

A mixing system adapted for installation within an oral care appliance and a method of preparing an oral care composition to be delivered to a mouthpiece of the oral care appliance are disclosed. Some of the disclosed systems and methods allow for the generation of an on-demand oral care composition for use in dental cleaning.

Disclosed is a teeth cleaning apparatus, including a first liquid reservoir, a teeth cleaner, a connector, and a liquid conveyer. The teeth cleaner includes a teeth cleaner body and a second liquid reservoir that is fixedly connected to the teeth cleaner body and transmits a teeth cleaning liquid to the teeth cleaner body during teeth cleaning. The connector is separable from the teeth cleaner, and the liquid conveyer transmits the teeth cleaning liquid in the first liquid reservoir to the second liquid reservoir when the teeth cleaner is connected on the connector.

A device, method, and system are provided for treating the oral cavity. The device includes a mouthpiece suitable for implementing a dental treatment, wherein the mouthpiece includes one or more stock elastomeric dental cover layers suitable for forming and maintaining a treatment cavity having a vacuum fluid seal, wherein the dental cover layers includes a layer over all the surfaces of the upper teeth and surrounding gums and/or a layer over all the surfaces of the lower teeth and surrounding gums, wherein each of the layers includes one or more hardened rigid or semi-rigid sections for enabling selected and/or differential collapsibility of the cover layers when exposed to vacuum pressure; and one or more treatment supply layers, and one or more flow channels in fluid communication with the treatment cavity so that the treatment supply layer can deliver and/or remove one or more treatment fluids from the one or more fluid sealed treatment cavities.

A system and method for forming a sterile dental pack is disclosed. The method includes preparing a first wrap and a second wrap; arranging a plurality of dental disposable supplies on the first wrap; and wrapping the plurality of dental disposable supplies within the first wrap and the second wrap to form an airtight container. Also disclosed is a sterile dental pack dispensing system. The sterile dental pack dispensing system may include a storage container with an opening, the storage container being configured to store a wrapped sterile dental pack; an output configured to receive the wrapped sterile dental pack from the storage container; and a fiber optic indicator configured to cause the wrapped sterile dental pack to move from the storage container to the output through the opening.

This disclosure relates to an oral care appliance and a method for use in oral care for cleaning the teeth of one or two arches using a mouthpiece forming a closed or nearly closed cavity. The mouthpiece is adapted to deform in response to pressure variations inside the cavity and create an action on the teeth. This disclosure includes a description of depression chambers and associated methods that can contribute to the operation of the oral care appliance by affecting the aforementioned pressure variations.

The aim of the invention disclosed herein is to control and regulate the stiffness and flexibility of an endodontic file exploiting its super-elastic and shape-memory characteristics. This result is achievable thanks to temperature-induced phase transformations of the file performed by a proper heating and cooling system managed by a control system in a handpiece. Different designs of the apparatus implementing the proposed solution are disclosed.
