The cartridge body has an external wall, a generally cylindrical internal chamber wall having an internal chamber wall diameter and enclosing a cartridge chamber, and at least one channel wall forming a channel (or groove) in the chamber wall. The piston has a generally cylindrical plug wall positioned adjacent to the generally cylindrical internal chamber wall. The cylindrical plug wall has a diameter substantially equal to the diameter of the cylindrical internal chamber wall. Dental material is conveyed into the cartridge chamber.
