Abstract: In the present invention, a dripless syringe is provided that includes a barrel having fluid therein, the barrel defining an open end and a nozzle opposite the open end, a plunger disposed at least partially within the open end and including a body and a push pin extending from one end of the body, a seal plate slidably mounted to the push pin and a bung disposed over the seal plate and the push pin and sealingly engaged between the seal plate and the barrel the seal plate enables the bung to remain in sealing engagement with the interior of the barrel while the plunger is moved within the barrel. Further, when pressure is removed to cease dispensing of the fluid, the pin allows the bung to retract and provide a negative pressure on the fluid to prevent drips of fluid from leaking out of the nozzle.

Abstract: Methods and kits for assessing the presence of, and for detecting cancer, notably oral cancer, are disclosed. Such methods and kits use one or more lectins operably linked to a fluorophore, wherein the lectin binds differentially to cancerous and non-cancerous tissues, and wherein the fluorophore facilitates visualizing the differential binding. The lectins are applied to the oral mucosa of a subject, the fluorophore is exposed to light, and cancerous regions of the mucosa are visualized. In certain embodiments, the lectin specifically binds to one or more of a ?-galactoside, an ?- or ?-N-acetylglucosamine, or a sialic acid moiety.

Abstract: A carpule device having an outer polygonal-shaped container and an inner container telescopingly fitted within the outer container. The outer container has a top wall having an opening, a closed bottom wall, and side walls extending between the top wall and the bottom wall. The inner container has a closed rupturable bottom surface, a top surface, side walls extending upward from the bottom surface to the top surface. A rib is located on the external surface of the inner container and forms a seal between the inner and outer container. The carpule includes a device for rupturing the bottom surface of the inner container, which is preferably a protrusion located on the bottom surface of the outer container or a brush located within the inner container.

Abstract: A needle assembly for dispensing fluids from a fluid source and for evacuating a cavity during an endodontic procedure and a method of using the needle assembly. The needle comprises a housing and a surgical needle in fluid communication with said fluid source. The housing comprises a first pathway containing said surgical needle, and a second evacuation pathway providing evacuation means for the needle assembly. The evacuation pathway is independent and external of the surgical needle.

Abstract: A portable medical apparatus for holding a plurality of surgical tools wherein at least one of said tools is electrically powered and includes a power supply cord and a power plug is disclosed. The apparatus comprises a housing having at least one electrical outlet for removably receiving said power plug is disposed within said inner shell. The housing includes an upstanding wall having at least one area for receiving and supporting a power supply cord. A removable enclosure lid is received by the housing. An upright member supports the housing and provides a passageway for a conductor in electrical communication with the electrical outlet. A base supports the upright member and includes a laterally extending leg having a channel for receiving the electrical conductor. The leg is apertured to receive a connector for attachment to the electrical conductor.

Abstract: A dental handpiece for applying dental material to polish a tooth. The handpiece includes a conduit and a plunger for dispensing dental material adjacent a polishing member. The plunger and the polishing member can be controlled by a drive means, which may move in both a forward and reverse direction. A removable prophy angle may contain the dental material.

Abstract: A unitary, one-piece dental irrigation tip for delivering fluids from a dental device to a dental site. The tip has a proximal end having releasable locking means for attachment to the device, and a distal end providing an opening for fluid delivery to the dental site.

Abstract: A disposable extension member for joining a dental handtool to a disposable, hollow, dental tip. The dental handtool includes a chuck for releasably retaining the extension member. The extension member has at least one fluid-tight passageway extending through its body for fluid flow from the dental handpiece to the dental tip. The extension member includes an adaptive releasable locking member having an internally threaded, cuplike end portion dimensioned for releasable threading engagement with the dental tip. The chuck provides easy and efficient clamping means to secure the extension member within the handtool.

Abstract: A dental handpiece for delivering a fluid from a fluid source to a dental attachment under a regulated pressure. The said handpiece includes a head portion having a socket arranged to receive the dental attachment. A fluid passageway is in fluid communication with the socket and the fluid source. A fluid pressure control fitting resides in the passageway. The fitting has an orifice with a cross-sectional area less than said passageway interior cross-sectional area. The handpiece may be arranged for the delivery of more than one regulated fluid.

Abstract: An adaptor for coupling a dental irrigation tip to an ultrasonic dental handpiece is disclosed. The dental handpiece is connected to a fluid source. The adaptor comprises an elongated body having a distal end for connection to the irrigation tip and a proximal end for connection to the dental handpiece. The elongated body has a through bore in fluid communication with the dental handpiece and the irrigation tip. In an alternate embodiment, the adaptor may replace the ultrascaling dental handpiece.

Abstract: Systems and methods provide for automated, cyclic delivery and evacuation of a treatment or irrigation solution from a tooth root pulp chamber and pulp canals. A manifold has a base member sized and configured to rest on a crown of an instrumented tooth and a top member sized and configured to couple with the base member to define an inlet chamber and an outlet chamber. The distal end of a needle is passed through an opening between the inlet and outlet chambers and extended distally beyond the base member into a pulp canal. The proximal end of the needle includes an opening in fluid communication with the inlet chamber. A solution is transferred from a fluid supply source to the inlet chamber and through the needle into the pulp chamber and pulp canals. The spent solution is evacuated from the pulp chamber and pulp canals through the outlet chamber.
