Abstract

Abstract:

Root canal irrigation is essential to disinfect the main root canal, the root canal isthmus, and the lateral root canals. Traditional syringe irrigation is the most widely used irrigation method. Due to the intricate three-dimensional structure of the root canal system, the fluid cannot penetrate all areas. Therefore, syringe irrigation does not flush out tissue residues and dentin debris well. This accumulated hard tissue debris may interfere with the sealing properties of the root canal filling material and hinder disinfection. Laser-activated irrigation has emerged as an effective root canal irrigation technique. The new Er:YAG laser swabbing mode has greatly improved the efficiency of removing debris and medication from root canals.This article summarizes the effectiveness and advantages of Er:YAG laser in root canal irrigation and the current status of the application of Er:YAG laser to root canal treatment.

Key words: root canal irrigation, Er:YAG laser, photon-induced photoacoustic streaming, shock wave enhanced emission photoacoustic streaming
