Abstract: The present invention relates to a device (1) for dispensing a pasty or liquid composition intended for a medical or dental use, and in particular for endodontic use. The device comprises a handle (1), a reservoir (2) for the pasty or liquid composition, at least one plunger (4) arranged to slide in the reservoir (2), at least one lever (3) arranged to be removably mounted on a mounting portion of the handle (10) and arranged to cooperate with the plunger (4) to cause said plunger (4) to slide in the reservoir (2) for the dispensing of the pasty or liquid composition contained therein when the reservoir (2) and the lever (3) are mounted on the handle (10). The lever (3) is arranged to be connected to the plunger (4) such that when the user presses on the lever (3) in the direction of the handle (10), the plunger (4) slides in the reservoir (2) along the longitudinal axis thereof and pushes the pasty or liquid composition out of said reservoir (2).

Abstract: Disclosed is an irrigation needle including an active part extending between a first end intended to be connected to an irrigation device and a second closed end, a central channel extending inside the active part and open at the first end and at least one opening arranged radially on the active part in the vicinity of the second end and communicating with the central channel for distributing an irrigation solution. The needle is obtained as one piece using a thermoplastic micro-injection moulding method.

Abstract: The invention concerns injectable bone filling cements, in particular hydraulic calcium phosphate cements, the latter being prepared from at least two initial liquid or pasty constituents comprising each a species reactive in solution or in suspension, the solidification process being initiated when said constituents are being mixed.
