The Antibacterial Effect of Electromagnetic Stimulation On In Vitro Endodontic Biofilms

Abstract

Non-surgical root canal treatment (NSRCT) is indicated for endodontic infection. However, it is generally indicated under conditions that have caused inflammation, infection, and/or necrosis of the pulpal tissue. In recent years, an electromagnetic stimulation (EMS) device has been created by the International Society for Electromagnetic Dentistry (Tominaga Dental Clinic, Naruto, Japan). This device transmits electromagnetic waves and is used to augment the disinfection of the RCT. This novel method may accomplish the RCT disinfection by creating a synergistic reaction via thermal and electrical energy, allowing the potential to enhance root canal disinfection [2, 3]. Japanese researchers have also found promising results with its synergistic use clinically [4, 5]. Previous results have shown an increased anti-microbial effect with synergistic use of sodium hypochlorite, but this study will explore the direct anti-microbial effect of electromagnetic stimulation.
