Abstract: A one-hand operated dispenser for metering dental compositions comprises a casing for accommodating the dental composition between a forward dispensing opening and a plunger which is slidable within the casing. The plunger is advanced by means of a threaded spindle which engages in a nut mounted at the casing rear end so as to be secured against rotation and axial displacement. The casing rear end is rotatably supported within a sleeve which in turn is detachably inserted in a handle. The sleeve is formed with an axially extending slot through which a finger is visible which is disposed at the rear end of the spindle. When the handle is gripped, the casing may be rotated between the thumb and index finger such that the spindle advances the plunger thereby urging the dental composition out of the dispensing opening. During the forward movement of the spindle the finger travels forwardly in the axially extending slot and indicates the level of the dental composition.
