摘要

An apparatus for introducing a drug, which is to be introduced into a tooth or a periodontal tissue, into a tooth or a periodontal tissue using an ultrasonic energy and causing little damage. The drug for introduction, which is a mixture to be introduced into a tooth or a periodontal tissue for a therapeutic purpose with the use of an ultrasonic energy and comprises a mixture of plasmid DNA or a drug with fine bubbles, is introduced into the tooth or the periodontal tissue by using an apparatus for drug introduction comprising an ultrasonic wave oscillator having at the tip thereof a detachable ultrasonic wave-oscillating unit whereby the target site of the tooth is irradiated with the ultrasonic wave, and a drug extruder for feeding the drug to be introduced into the tooth toward the target site.
