Use of electromagnetic stimulation on an Enterococcus faecalis biofilm in root canal treated teeth in vitro
… effect of EMS against an established biofilm of Enterococcus faecalis. Materials and Methods: Single rooted teeth were cut to a standardized length (12 mm) and instrumented with a 45.05 Wave One Gold reciprocating file. Specimens were sterilized and inoculated with E. faecalis, which grew for two …
