<P>PROBLEM TO BE SOLVED: To provide a probe syringe which makes an examination completely in no contact with a pulp exposure section by impedance measuring by employing ionic conductive paste. <P>SOLUTION: The probe syringe 60 of this invention has a leading edge which discharges an ionic conductive paste layer 38 on the affected tooth and consists of a discharging section formed in a way able to connect the inside and exterior of the probe syringe, a cylindrical section, which succeeds the discharging section and holds the ionic conductive paste, and a piston forced into the cylindrical section, and the probe syringe 60 forms an electric conduction circuit including the ionic conductive paste in no contact with the pulp exposure section by passing an electric current to the exterior of the probe syringe through the ionic conductive paste layer 38. <P>COPYRIGHT: (C)2008,JPO&INPIT |
