摘要： A nozzle head (5) for a powder jet device (1), for use in applying dental material, comprises a first fluid flow path (8) for delivering a powder/fluid mixture to a first discharge nozzle (8A). A second fluid flow path (6) is provided for delivering a liquid to a second discharge nozzle (6A) located adjacent the first discharge nozzle (8A), so that the materials discharged by the first and second discharge nozzles combine at a desired location to form a dental composition. A nozzle-clearing member (10) is located inside the nozzle head and is movable to remove powder material from the first discharge nozzle when the flow of powder/fluid mixture to the nozzle ceases.
