A single dose dental applicator which includes a capsule with a first end and a second is disclosed. Extending outwardly from the first end of the capsule is an elongated nozzle. The end of the nozzle has a tip which is frangible. The second end of the capsule has a flat portion which acts as a handle. A quantity of dental varnish is housed within the capsule. In order to use the applicator, the dentist breaks the tip of the nozzle and inserts the nozzle into the cavity. The dentist then holds the handle and squeezes the capsule, thereby releasing the varnish housed therein. The quantity of varnish housed within the capsule is sufficient to line one tooth. The capsule is then discarded.

A powdering attachment for applying powder to tooth surfaces is disclosed. Such an attachment is useful in operations such as preparations of a tooth before the use of dental equipment in the CERECnull family of products. The powdering attachment may be connected to a dry air syringe that is adapted to allow for the removable connection of dental accessories such as the powdering attachment. When connected to the dry air syringe, the control valve mechanism on the dry air syringe controls the air flow into the powdering attachment. An air tip assembly is given as an illustration of another dental accessory that may be attached to the modified dry air syringe.
摘要:
A pneumatic dental care device for private use which by means of a combination of air, liquid and powder at high pressure cleans the user's teeth and removes plaque and discoloration. The device consists of a base unit (100) and a hand unit (300) which are connected via a flexible, sheathed tube and wire bundle (200). The base unit contains a microcompressor (120), a liquid container (130) and a powder container (140). Liquid and/or powder are discharged at high pressure through an exchangeable nozzle unit (400) on the hand unit. The nozzle unit consists of one or more flexible (bendable) jet stems (401). The microprocessor, the powder container and the liquid container can be replaced by an exchangeable compressed air tank and/or pressurised liquid and/or powder containers in different configurations. The components of the device can also be integrated into a hand-held unit.

This invention relates to an oral therapeutic delivery appliance. Using this oral therapeutic delivery appliance medicaments may be delivered to oral soft tissues, where medicaments are easily absorbed. To aide the delivery of medicaments to oral soft tissues the oral therapeutic delivery appliance contains a therapeutic pooling reservoir where the medicaments may be placed. The oral therapeutic delivery appliance may be used to treat or aide in the treatment of various oral maladies such as periodontal disease (i.e., gum disease) as well as treating or aiding the treatment of other physical ailments and systemic diseases (e.g., diabetes and other chronic diseases which require either single, intermittent or constant dosing of medicament).
