Abstract

The goal of root canal therapy is to get rid of the bacteria that are growing in a tooth’s root canals. An instrument is inserted into the root canals in many conventional methods of root canal irrigation. However, the treatment carries clinical risks, such as instrument fracture and irrigation liquid extrusion through the apex of the canal, and bacteria removal is frequently incomplete in the apical region of the root canal. We propose a novel high-intensity ultrasound irrigation system that is remotely generated, has improved irrigation performance, and reduces clinical risk. A transducer positioned outside of the target tooth generates the powerful ultrasonic waves used in our device. In order for the generated ultrasonic waves to enter the root canals, they are directed. Acoustic cavitation and vapor bubble formation occur in the target tooth’s root canals. Vapor bubbles’ dynamic motions have remarkable cleaning effects. We tested the proposed system’s cleaning capabilities and compared it to other conventional irrigation methods using root canal models. The findings demonstrated an improvement in cleaning performance by demonstrating that the proposed system can completely remove biofilm from the root canal models’ apical regions. While using the proposed system, we also measured pressure at the apex of an extracted tooth’s root canals. The fact that our system had a lower pressure than the syringe irrigation method suggests that the risk of the irrigation liquid extruding from the apex is lower. The proposed system can clean multiple root canals in a tooth simultaneously with a single treatment because it does not require instruments to be inserted into the canal. In terms of irrigation performance, clinical safety, and ease of treatment, the proposed device would represent a breakthrough in root canal treatment.
