A dispenser for controllably heating a compule of dental material removably inserted in the dispenser and for extruding dental material from the compule. The dispenser includes an elongated tubular barrel having a substantially semi-cylindrical front end to accommodate the body of the compule, a cavity at the front end of the dispenser open to the atmosphere and a slot disposed transverse to the longitudinal axis of the for accommodating an end flange of the compule when the compule is inserted into the dispenser. The dispenser further includes a housing having one end connected to the tubular barrel and an opposite end having an extended handle in the form of a pistol grip, a plunger reciprocally mounted in the tubular barrel having a piston extending in alignment with the longitudinal axis of the cavity and a manually movable lever arm coupled to the plunger by means of a rack and pinion mechanism to dispense dental material from from the dispenser. The lever and handle are adapted to be held in one hand for manually controlling the movement of the plunger relative to said handle. The dispenser further includes a heating unit disposed in the cavity at the front end of the dispenser for heating the compule, a battery supply, and an electrical control unit connected to the battery supply for controlling the supply of electrical energy to the heating unit, with visual indicators for indicating temperature and battery level conditions. |
