A micro-needle device (100, 200, 300) for delivering a dental local anesthetic that includes a micro-needle array (102, 202, 302) and a hollow spheroid shaped container (108, 208, 308). The micro-needle array has a base (104, 204, 304)and two or more of an elongate micro-needle (106, 206, 306). The elongate micro-needle has an interior surface (110, 210, 310) defining an opening (112, 212, 312) through the elongate micro-needle and the base has a first major surface (114, 214, 314) and a second major surface (116, 216, 316) through which the opening of the elongate micro-needle passes to provide a passage across the base. The hollow spheroid shaped container includes an inside surface (120, 220, 320), where the first major surface of the base and the inside surface of the hollow spheroid shaped container define a volume that is in fluid connection with each opening of the two or more of the elongate micro-needle. This allows the dental local anesthetic to flow from the volume of the micro-needle device through the opening of the two or more of the elongate micro-needle.

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.

An oral cavity wetting system includes a stable detachable attachment to at least one tooth and a conduit or liquid line for delivery and storage of fluid and at least one opening for the exit of fluid inside the oral cavity.

An oral appliance and a method of making the oral appliance for delivering a medicament to an oral cavity are provided. The method comprises forming a non-porous material into a portion of the oral appliance; and applying a porous material to one or more discrete regions of the portion of the oral appliance to make the one or more discrete regions of the oral appliance porous thereby forming the oral appliance.

The invention is directed to providing, at the exit from the nozzle of an irrigator, an intermittent gas-liquid jet for enabling effective cleaning, while being easy to use, A bulb (1) has an aerator introduced therein which is in the form of a tubular element (7) with open tips (71, 72) and a perforation region (73) in the side wall of the element (7), the region having at least one hole. The end of the tubular element (7) on the open-ended side is freely disposed in the cavity of the bulb (1), and the tip (71) is disposed with clearance from the base of the bulb.

The invention provides a device for the practice of oral medicine, including dentistry. Specifically, the invention relates to a guiding device that helps to prevent injecting beyond the pterygomandibular space during inferior alveolar nerve block for which purpose the injection is administered in the vicinity of the inferior alveolar nerve. The device has a retro-mandibular tip (12) operably linked to a guide tube (14) by a connecting unit (20, 22, 24), the guide tube (14) is adapted to receive a syringe and has a stopper mechanism (19) to stop the advancement of the syringe such that its needle is located at a predetermined distance from the posterior edge of the mandibular ramus.

Apparatuses, methods of use, and methods of manufacture are described herein for a dental guide. The dental guide may include an elongate member defining a first end and a second end, a needle support proximate the first end, the needle support defining an aperture structured to receive a needle, and a fixed hub proximate the second end.

A needle-free injector assembly and vial adapter therefor is provided. The assembly comprises barrel containing a shaft assembly, a power injection unit attached at one end of the barrel, and a vial adapter for holding a vial of medicament to be injected connected at another end. The vial adapter comprising a vial cartridge holder with a protector tube for holding the vial of medicament, a cutting means for perforating the vial seal, and a locking connection with the assembly nozzle. The assembly may be used in dental applications, such as for the administration of anesthetic to oral tissue.

A dental appliance for delivering medicaments to teeth and gums which comprises a dental tray in which one or more recessed chambers are formed in the interior of buccal tray walls and/or lingual tray walls. The recessed chambers provide a space where a medicament can be retained when the appliance is worn by a subject.

A dental tool can include a hand piece; a head for inserting and removing from an end of the hand piece, wherein the head comprises a frame comprising at least two frame arms; and a frozen liquid contained within the frame by the at least two frame arms. The frozen liquid can be placed onto a patient's tissue in the mouth to reduce or eliminate pain from an injection of anaesthesia for dental work. The hand piece can also include a mechanical motion module that imparts mechanical motion to the tissue along with cold from the frozen liquid.
