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 DEG . 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.
