Abstract: Disclosed herein is a dental device for delivering fluid continuously while activated in an endodontic application. The dental device includes a hollow needle having a tip end and a connector portion; and a handle. One end of the handle is configured to be affixed to the connector portion of the hollow needle. The opposite end of the handle is capable of being attached to an endodontic handpiece or a sonic agitator for the activation. The connector portion includes at least one tube connector that is an integral part of the connector portion of the hollow needle or a plurality of openings on the connector portion to accommodate the hollow needle to a connector. The connector is a modular fluid delivery connector which is removable from the needle such that it can be reused.

Abstract: A custom drill guide and a method, system, and computer readable media for determining a number and location of canals in the tooth in order to create a custom drill guide to match the anatomy for proper orientation of high speed burs and files for cleaning/shaping. By knowing where the canals are located within the tooth, a relatively small access opening may be created, the small access opening provides for a strong crown during the restoration process.
