Effect of electric currents on antibacterial effect of chlorhexidine against biofilm: An study.

Background: This study was mainly aimed to evaluate the effect of high-frequency alternating currents (AC) applied by an electronic apex locator (EAL) on the antibacterial properties of chlorhexidine (CHX) on biofilm.

Material And Methods: The root canals of 120 extracted human single-rooted teeth were prepared using Gates-Glidden drills and hand K-files. After contaminating the root canals with , they were incubated for 60 days.
