Summary: | ABSTRACT
Aim
This study was conducted to evaluate the antimicrobial activity of 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) and BioPure MTAD when used as a final rinse against
Enterococcus faecalis
.
Materials and methods
Sixty single-rooted premolars were biomechanically prepared, inoculated with E. faecalis and divided into various groups. These were then irrigated with the test irrigants and tested microbiologically for growth of
E. faecalis
immediately after irrigation and after 48 hours.
Results
Statistical analysis showed that there was a significant difference between the antibacterial activities of BioPure MTAD, 2% CHX and 5.25% NaOCl at 5 minutes; however, the antibacterial activities of the three irrigants were comparable after 2 days of irrigation
Conclusion
The present study concludes that BioPure MTAD is as effective against
E. faecalis
as 5.25% NaOCl and more effective than 2% CHX.
Clinical significance
E. faecalis
is one of the most resistant intracanal species and a possible cause of root canal failure. Many authors have stressed the importance of using antimicrobial irrigants during chemomechanical preparation to ensure complete disinfection. Therefore, various irrigating solutions have been used during and immediately after root canal preparation to remove debris and necrotic pulp tissue and to eliminate microorganisms that cannot be reached by mechanical instrumentation.
