Abstract
Devices and methods for the application of materials to an interior space of a tooth, such as the extirpated pulp chamber and/or root canals of the tooth subsequent to root canal surgery. The device has one or more syringe-like pistons and associated chambers for drawing a vacuum within an extirpated pulp chamber and applying cleansing, sealing, and/or filler materials into the tooth under continued vacuum pressure to ensure complete and thorough application.
Claims27
A device for delivering a fluid to an interior space of a tooth, the device comprising:
- vacuum chamber;
- a dispensing chamber adapted to receive a fluid material;
- a first conduit having a first end in fluid communication with said vacuum chamber and a second open end;
- a second conduit having a first end in fluid communication with said dispensing chamber and a second open end;
- a first plunger disposed within said vacuum chamber and configured for movement to draw air into said vacuum chamber through said second open end of said first conduit;
- a second plunger disposed within said dispensing chamber and configured for movement to discharge the fluid material from said dispensing chamber through said second open end of said second conduit;
- and
- a sealing surface disposed proximate said second open ends of said first and second conduits and operative to at least assist in forming a substantially air-tight seal between the first and second conduits and the interior space of the tooth when said first and second conduits are positioned in fluid communication with the interior space,
- wherein the vacuum chamber and the dispensing chamber are positioned within a unitary body configured for handheld use on a patient.
A device for delivering a fluid to an interior space of a tooth, the device comprising:
- a vacuum chamber;
- a plurality of dispensing chambers adapted to receive at least a corresponding plurality of fluid materials;
- a vacuum conduit having a first end in fluid communication with said vacuum chamber and a second open end;
- a plurality of dispensing conduits having first ends respectively in fluid communication with said plurality of dispensing chambers and further having respective second open ends;
- a vacuum plunger disposed within said vacuum chamber and configured for movement to draw air into said vacuum chamber through said second open end of said vacuum conduit;
- a plurality of dispensing plungers respectively disposed within said plurality of dispensing chambers, each dispensing plunger configured for movement to discharge one of the fluid materials from one of said dispensing chambers through one of said second open ends of a corresponding one of said dispensing conduits;
- and
- a sealing surface disposed proximate said second open ends of said vacuum and dispensing conduits and operative to at least assist in forming a substantially air-tight seal between the vacuum and dispensing conduits and the interior space of the tooth when the vacuum and dispensing conduits are positioned in fluid communication with the interior space,
- wherein the vacuum chamber and the dispensing chambers are formed within a unitary body configured for handheld use on a patient.
A method of delivering a fluid material to an interior space of a tooth using a device including a first piston disposed within a first chamber and a second piston disposed within a second chamber containing the fluid material, the first and second chambers being formed within a unitary body configured for handheld use on a patient, the method comprising:
- positioning the device to engage an opening of the tooth leading to the interior space with the first and second chambers in sealed fluid communication with the interior space;
- manually holding the unitary body while moving the first piston to at least partially evacuate the interior space;
- and
- manually holding the unitary body while moving the second piston to dispense the fluid material from the second chamber into the interior space.
