Antibacterial Efficiency of three Different Irrigation Methods in Infected Roots Infected with Enterococcus Faecalis...

Area of Science:

• Endodontics
• Microbiology
• Biomedical Engineering

Background:

• Enterococcus Faecalis is a primary pathogen in endodontic failures due to its resilience.
• Effective elimination of E. Faecalis biofilms is critical for successful root canal treatment.

Purpose of the Study:

• To compare the antibacterial efficacy of three irrigation techniques: passive ultrasonic, XP Endofinisher file, and Laser Diode 810 nm.
• To evaluate these methods against E. Faecalis biofilm in infected root canals.

Main Methods:

• 48 single-canal teeth infected with E. Faecalis biofilm were divided into four groups.
• Irrigation methods included passive ultrasonic (Ultra X), XP Endofinisher file, and Laser Diode 810 nm, plus a control.
• Standardized irrigation protocol with sodium hypochlorite (NaOCl) and EDTA was followed.

Main Results:

• All tested irrigation methods significantly reduced bacterial colonies compared to the control group.
• Laser Diode 810 nm demonstrated significantly higher antibacterial efficacy (p<0.05).
• Passive ultrasonic irrigation (Ultra X) was more effective than the XP Endofinisher file (p<0.05).

Conclusions:

• Passive ultrasonic, XP Endofinisher file, and Laser Diode 810 nm irrigation are effective in reducing endodontic bacteria.
• Laser Diode 810 nm offers superior antibacterial performance in E. Faecalis infected root canals.
