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.

A dental delivery system can comprise a first fluid conduit for supplying fluid via the delivery system to a handpiece connected to a distal end of the conduit, a plurality of flow control adjusters positioned on the delivery system at a location remote from the at least one fluid conduit, and an indicator circuit comprising a plurality of sensors and a plurality of indicators corresponding to the plurality of flow control adjusters. A first flow control adjuster of the plurality of flow control adjusters can be operable to change a fluid flow rate in the first fluid conduit. A first sensor of the plurality of sensors can be operable to trigger a first indicator of the plurality of indicators in response to predetermined motion of the first fluid conduit to indicate that the first flow control adjuster is associated with the first fluid conduit.

A dental syringe tip system for attachment to a dental syringe. The dental syringe tip system can include components such as an outer core, an inner core, and a carrier which can be combined in a multitude of combinations to achieve different fluid flow characteristics, such as discharge pressure and discharge pattern, through the dental syringe tip. The outer core and inner core can have passages designed to modify fluid flow characteristics. In addition, the outer core and inner core can have additional connectors for receiving fluids from sources other than a dental syringe. Some or all of the components can be separate to be assembled by a manufacturer or an end-user. Assembly of multiple components can be facilitated by retention features located on the components.

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.

Described herein are systems and methods for providing personalized oral irrigation. One variation of a system for personalized oral irrigation comprises a fluid reservoir and a customized oral insert in fluid communication with the fluid reservoir. The oral insert comprises an arrangement of fluid openings positioned based on the individual oral or dental structures of a user's teeth to provide a customized fluid flow over the user's teeth. Also described herein are methods for generating an arrangement of fluid openings in a customized oral insert.

Embodiments disclose a disposable protective assembly apparatus for a dental syringe body of a dental syringe. The apparatus is a combination of a disposable syringe tip and a disposable protective sleeve, the sleeve being pre-attached to the syringe tip, and the sleeve being in a pre-folded position to be quickly and easily slid over the dental syringe prior to a dental operation.

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 dental procedure performed on target tissue without anesthetic or anesthesia including preconditioning the target tissue using a laser device constructed to produce light in a wavelength range of 2750 nm to 11500 nm, to provide an energy fluence in a range of 50 J/cm.sup.2 to 100 J/cm.sup.2, and to operate in a free running pulsed mode providing 60 μm bursts at a frequency of at least 50 Hz. Preconditioning includes selecting a combination of average optical output power and preconditioning time to administer low level laser therapy. The laser device is adjusted to deliver light through the light guide of the laser device at the selected average optical output power. Light delivered through the light guide of the adjusted laser device is directed toward the target tissue for the selected preconditioning time providing analgesia to the target tissue. Oral tissue is removed from the preconditioned target tissue during analgesia.
