Abstract: A dental clinical apparatus having a function which conventional instruments for dental treatment have not had and having a novel constitution. The dental clinical apparatus includes a syringe which has a fluid jetting system for dental treatment and a plasma jet applying means for producing a plasma jet from the end by allowing a low-frequency high-voltage power supply to apply a low-frequency high voltage between electrodes on the outer peripheral surface of a rare gas tube through which a rare gas having a low dielectric breakdown voltage under the atmospheric pressure is flowed, and thereby causing electrical discharge.
