ABSTRACT:
A dental composite cartridge is made of a plastic material molded to define an elongated cylindrical hollow body portion forming a reservoir, and a discharge nozzle portion. A piston is disposed within an open end of the hollow body after the body is filled with dental composite material. The hollow body and the discharge nozzle define a planar end wall which intersects the longitudinal axis of the hollow body at an angle of about 45.degree.. The interior design of the hollow body and its angled planar end wall enables a simple, easy to manufacture and cost-effective piston to be used in the hollow body for discharging dental composite material from the reservoir.
