Abstract: A tip assembly for use with a dental tool, the tip assembly comprising a housing for attaching to the dental tool, at least one aspiration needle having a passageway extending at least partially through the aspiration needle, a substantial length of the aspiration needle, or at least from one end to the other end of the aspiration needle, the passageway providing a single continuous path to aspirate the irrigant and/or debris from the root canal cavity of the tooth, and at least one irrigation needle having a passageway extending at least partially through the irrigation needle, a substantial length of the irrigation needle, or at least from one end to the other end of the irrigation needle, the passageway provides a continuous flow path for delivering fluid/irrigant from a reservoir in communication with a proximal end of the irrigation needle to the distal end of the irrigation needle and into a root canal/coronal opening of a tooth.

Abstract: A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.
