Comparative Evaluation of the Antibacterial Efficacy of Metronidazole, Chlorhexidine, and Normal Saline as Laser- and Sonic-Activated Intracanal Irrigants Against Enterococcus faecalis: In Vitro Study Protocol

This study aims to provide evidence-based insights into optimizing root canal disinfection protocols by evaluating and comparing the synergistic effects of antimicrobial agents and advanced activation techniques. The findings could contribute significantly to improving endodontic treatment outcomes and reducing the incidence of persistent infections caused by E. faecalis.
