ABSTRACT:
Dental or endodontic instruments such as drills, files, rasps, broaches, reamers, and the like are arranged to allow radiation of electromagnetic energy into a man-made or natural cavity in the tooth under treatment. The energy may be in the form of microwave or radio-frequency (RF) radiation. The energy raises the temperature of the surrounding tooth material, which tends to disinfect the material as a direct consequence of the temperature. Also, if a disinfectant material is additionally introduced into the tooth cavity, the temperature of the disinfectant material itself may be raised, which enhances its activity. In the particular application to the removal of degenerated pulp, the instrument may be introduced, and electrical or electromagnetic power applied to coagulate the pulp about the instrument, allowing more complete removal of the pulp. The dental instrument may be used with an RF energy delivery system for application of particular amounts of energy per unit time (power). The RF power may be carried through miniature coaxial cables through the dental instrument itself, to enable radiation directly into the interior of the tooth. For this purpose, in some embodiments of the invention the dental instrument includes a portion formed from a dielectric material which allows the energy to pass therethrough. In a particular embodiment, a dental drill includes an antenna near the distal end thereof, a capacitive top cap of which is made from hardened material shaped for removal of tooth material.
