PROBLEM TO BE SOLVED: To provide an exchangeable nozzle member for injecting dental photosensitive fillers, which facilitates the filling of fine defective parts of teeth with the dental photosensitive filler hardend with polymerization by active light beams irradiation without mixed with bubbles. SOLUTION: In the nozzle member 1 for injecting dental photosensitive fillers which is externally fitted and mounted on a fitting part 2a at the tip of a syringe-like dental photosensitive filler housing container 2 with the dental photosensitive filler A housed therein, a very tiny recessed part 1b is formed on the internal surface of a part thereof to be externally fitted onto the fitting part 2a. With the fitting part 2a fitted internally, the entire internal surface containing the internal surface of the fitting part 2a at the tip of the dental photosensitive filler housing container 2 is tapered in parallel with the direction of getting the dental photosensitive filler A extruded or toward a nozzle 1a. This form shows no stepped part possible orthogonal to the direction of getting the dental photosensitive filler A extruded or expanding gradually. COPYRIGHT: (C)2003,JPO
