The invention provides a method of extruding dental material from a capsule-like cartridge, by providing a capsule-like cartridge having an elongated body and a nozzle. The elongated body has an inner chamber wall enclosing dental material. The nozzle has an inner channel wall, and a channel wall exit orifice rim. The inner chamber wall has a chamber wall exit port rim, opening between the inner chamber wall and the inner channel wall. The chamber wall exit port rim has a chamber wall exit port rim effective diameter D1. The inner channel wall has an inner channel wall effective diameter D2. The inner channel wall effective diameter D2 effectively is greater than the chamber wall exit port rim effective diameter D1.
