Abstract:
A dental capsule for dispensing a dental material directly to a prepared tooth by a syringing technique comprising:a body portion defining a reservoir for containing a predetermined amount of dental material, said body portion having an internal diameter D, and said body portion having an opening at one end and a discharge nozzle at the other end, said discharge nozzle being angularly disposed relative to the axis of said body portion, a passageway extending through said discharge nozzle terminating at a discharge orifice, said passageway having an internal diameter whereby the ratio of said internal diameters dâ€³``Dâ€³``range between 0.60 to 1,said discharge nozzle having a wall thickness which progressively decreases toward said discharge orifice, an elongated displaceable piston for sealing said opening, said piston having a diameter sized to be snugly received in said body portion and said passageway, said piston being sufficiently flexible so as to extend through said passageway angularly disposed relative to said body portion so as to extrude all of a dental material disposed in said passageway, wherein said walls of said discharge nozzle are sufficiently flexible to permit said piston to extend into said passageway.
