Abstract: A plaque biofilm is a bacterial biofilm that is a soft, unmineralized bacterial population that is encased in a matrix that adheres to each other, or adheres to the surfaces of teeth, interdentals or prostheses and can not be washed away by water. It is an independent micro-ecological environment with structural, morphological, and metabolic activities, and its resistance is many times that of plankton. The researchers found that low-frequency ultrasound can improve the penetration of drugs in biofilms, so as to better play a bactericidal effect. It has a good clinical application prospects. This article reviews the research progress of low-frequency ultrasound on the permeation of dental plaque.

Key words: plaque biofilm, low-frequency ultrasound, permeation
