AI Technical Summary

Technical Problem

Conventional root canal cleaning methods face challenges in effectively cleaning complex and curved root canals due to the structural limitations of miniaturized dental instruments, which hinder the delivery of high-power ultrasonic energy and are prone to instrument fracture, and the formation of dissolved gas bubbles interferes with cleaning power.

Method used

A root canal cleaning device that transmits high-power ultrasound through a liquid medium using a vibrating horn and acoustic resonator to generate and control vapor bubbles, eliminating the need for direct instrument insertion and minimizing acoustic attenuation.

Benefits of technology

The device achieves thorough cleaning of the entire root canal by generating high-power ultrasound, preventing bubble lock, and reducing the risk of instrument fracture, while enhancing cleaning efficiency and applicability in the oral cavity.

Abstract

Disclosed are a root canal cleaning device and an operating method thereof. The disclosed root canal cleaning device comprises: a vibrator which generates a first acoustic wave; an ultrasonic horn which amplifies the first acoustic wave generated by the vibrator; an acoustic resonance unit which causes the first acoustic wave amplified by the ultrasonic horn to resonate and emits a second acoustic wave toward the root canal; and a liquid medium supply unit including an inlet through which is injected a liquid medium that transmits at least one of the first acoustic wave and the second acoustic wave to the root canal, and a first passage through which the liquid medium moves, wherein vapor bubbles are generated and collapse within a cleaning solution inside the root canal or within the liquid medium delivered to the vicinity thereof, together with the first acoustic wave or the second acoustic wave, thus enabling the removal of materials to be cleaned from inside a tooth, including the root canal.
