The compule contains a dental material. The adapter includes a coupling part that defines openings for attaching the adapter to the compule and to attach the adapter to the dental hand piece.A part of the plunger extends through an aperture and engages the piston rod. A breakable tab connects the coupling part and the part of the plunger and breaks during the distribution of the material. The part of the plunger is then movable in relation to the coupling part. A tip for use with a dental hand piece includes a housing that defines a chamber.A needle extends from the housing and defines a lumen having an opening from which the dental material is dispensed. A plunger slides within the chamber to push the material through the lumen and includes a tooth rib which seals the plunger against the camera during the sliding movement of the plunger. 1 / 1
