Purpose

The aim of this in vitro study was to assess and compare the antimicrobial efficacy

of different electrochemically-activated solutions (ECA) and contemporary

irrigants, in root canals infected with Enterococcus faecalis, used with or without

EndoActivator (EA).

Materials and methods

A hundred single-rooted human teeth were prepared. Ninety of the root

segments were infected with E. faecalis for four weeks, and divided into eight

test groups (n = 10) (four with and four without EA sonication) and a positive

control (n = 10). The irrigants tested were electrochemically-activated solutions

produced by the Medilox® (ECA-MX) and Envirolyte® devices (ECA-EN), 2%

CHX and 2.5% NaOCl. The root specimens were irrigated with 5 mL of the test

solution, with additional sonic agitation applied to the EA groups. The dentine

samples that were obtained from the walls were cultured, and the antibacterial

efficacy was evaluated by counting the colony-forming units.

Results

The ECA-EN, 2.5% NaOCl and 2% CHX were more effective than the ECA-MX (p <

0.05) with the addition of EA sonication, showing no statistical difference in the

elimination of E. faecalis.

Conclusion

The ECA-EN shows potential as an endodontic irrigant, while EA usage gives no

benefit in reducing bacteria from root canals.
