The aim of this study was to compare the effect of atmospheric pressure plasma (APP) with sodium hypochlorite (NaOCl) or the combination of APP and NaOCl on Enterococcus faecalis biofilm in root canals of extracted human teeth. The disinfection efficiency was determined as the logarithm of the number of colony-forming units (CFU). Additionally, scanning electron microscopy (SEM) was used to visualize the treatment effect on biofilm. The adjunctive treatment with Plasma+O-2 has a small additive, albeit statistically not significant effect in the CFU reduction of an E. faecalis biofilm compared to the 12min monotherapy with NaOCl. The effectiveness of Plasma+O-2 could be significantly increased by longer treatment time.
