Root Canal Disinfection Potential of 5.25% Sodium Hypochlorite, 2% Chlorhexidine and 810nm Diode Laser-A Comparative In vitro Antimicrobial Study

International Journal of Oral and Craniofacial Science
Research Article
Background: The eradication of persisting bacteria, such as Enterococcus faecalis, is crucial for the long-term preservation of the endodontically treated tooth.
Context and Purpose of the study: The aim of this research was to evaluate and compare the root canal disinfection potential of 5.25% sodium hypochlorite, 2% chlorhexidine gluconate and 810nm diode laser against control.
Results: A djunctive use of chemical disinfection by either 5.25% sodium hypochlorite or 2% chlorhexidine led to 100% microbial eradication as against diode laser which achieved 97.7% reduction as compared to baseline microbial count and 68.42% reduction after mechanical cleaning at the same dilutions.

Main findings: Chemicals used in the study achieved greater disinfection than diode laser irradiation.
