  • Patent number: 7448867
    Abstract: An apparatus for dispensing material during a dental or endodontic procedure includes a housing having a motor with an output. A needle heating member including a chamber may receive a prefilled needle of dispensing material. A heater at least substantially surrounds the chamber for heating the material in the needle. A plunger is used to expel the material from the needle during activation of the motor. A reusable protective sheath is provided for disposition on the outside of the housing. A method of manufacturing a needle for use and dispensing a material during a dental or endodontic procedure includes drawing a blank of metal having a closed distal end, bending the blank at a desired angle, and removing a portion of the drawn metal from the distal end to open the distal end thereby forming the dispensing needle.
