Abstract: A syringe-type device for supplying dental material to a dental restoration site includes a syringe body, a syringe connecting body, and an activation component. The syringe body has an outlet and a dental material retaining space for retaining therein a dental material. The syringe connecting body has an upstream opening and a downstream opening and is connectable to the syringe body such that dental material which has exited the syringe body through the outlet thereof flows through the upstream opening into the syringe connecting body and subsequently flows through the downstream opening to the dental restoration site. The activation component is disposable at the outlet of the syringe body and, in a non-actuated condition thereof, at least partially blocks the flow of dental material from the syringe body into the syringe connecting body and, in an actuated condition thereof, permits a relatively greater flow of dental material.

Abstract: A cavity filling apparatus is provided for filling a cavity in a cavity containing member such as a tooth and a restorative dental piece. The cavity filling apparatus includes a filling mass ready space for retaining therein a filling mass, a suction conduit, and an adapter having an adapter channel. In a suction disposition of the cavity filling apparatus, a vacuum is produced in the cavity of the cavity containing member, via the adapter channel, by suction action through the suction conduit. In connection with a filling disposition of the cavity filling apparatus, the filling mass is injected into the cavity, via the adapter channel, from the filling mass ready space. The cavity filling apparatus also includes an assembly for switching the cavity filling apparatus between its suction disposition and its filling disposition.

Abstract: A flushing apparatus for cleaning a cavity space of a cavity space containing member such as a tooth or a restorative piece is provided. The flushing apparatus includes a working space in communication with a pump for producing a vacuum in the working space, a supply conduit communicated with the working space, and an outlet conduit with the working space. The working space is disposed in fluid communication with the cavity space and an oscillation generator creates oscillatory movement in the flushing fluid which is fluidly communicated into the working space and the cavity space. An adapter communicates the working space with the cavity space. The flushing apparatus is operable to place the working space in a vacuum condition relative to the tooth or the restorative piece.
