Abstract

The purpose of this study is to evaluate the effectiveness of the antibiofilm feature of ultrasound by compiling researches on the use of therapeutic ultrasound in biofilm removal. The literature was scanned with the keywords “biofilm removal”, “therapeutic ultrasound”. Therapeutic ultrasound application can generate two possible bacterial responses, in the form of inducing bactericidal and bacterial growth. The bactericidal effect has been reported in different studies where high intensity occurs at low frequency, induction of bacterial growth occurs at low intensity and low frequency. For bactericidal effect with antibiofilm properties, ultrasound should be applied at high intensity and low frequency. The combined use of ultrasound with other methods, especially antimicrobials, ensures effective destruction of biofilms and prevents the development of antibiotic resistance

Keywords

Therapeutic ultrasound, biofilm removal, antibiotic resistance, antibiofilm, microbubble, cavitation effect
