Dental ultrasonic drug delivery system and dental ultrasonic drug delivery method

A dental ultrasonic drug delivery system for delivering a drug to a target using a dental therapeutic probe for applying ultrasound, wherein

• the drug is delivered to the target in a mixed state with nanobubbles, and
• the dental therapeutic probe includes a probe body and a delivery probe attached to the probe body and is configured to deliver the drug to the target, wherein the delivery probe is selected from the group consisting of:
• (1) a root canal insertion probe, which is configured to be inserted into a root canal to cause ultrasound to propagate in the root canal, and includes an apical area irradiation part for irradiating an apical area of the root canal with ultrasound and a lateral branch irradiation part for irradiating a lateral branch of the root canal with ultrasound;
• (2) a dental caries therapeutic probe, which causes ultrasound to propagate in a dental caries portion, the ultrasound being generated by an ultrasonic transducer provided in the probe body in the case of selecting the dental caries therapeutic probe;
• (3) a periodontal disease therapeutic probe, which is configured to be inserted in a periodontal pocket to irradiate a periodontal disease portion with ultrasound, and includes a tubular body, a periodontal pocket irradiation part which is located at a distal end of the tubular body and causes ultrasound to propagate to the periodontal pocket, and a drug delivery tube which is provided inside the tubular body and delivers the drug, in a mixed state with nanobubbles, to the periodontal pocket;
• and
• (4) a hyperesthesia therapeutic probe, which is configured to irradiate a hyperesthesia portion with ultrasound, and includes a wedge-shaped defect portion pad formed by modeling an impression of a wedge-shaped defect portion of tooth enamel, a transducer part for generating ultrasonic vibration, and a fluid path, which is provided between the transducer part and the wedge-shaped defect portion pad, and through which a fluid flows.
