Comparing intracanal medicaments and their action against Enterococcus faecalis

This is the authors' abstract. We don't add key points for this paper.

Complete elimination of microorganisms is essential for endodontic success, but Enterococcus faecalis frequently persists in treated canals. Therefore, it is of interest to compare the triple antibiotic paste (TAP), 0.05% octenidine dihydrochloride (OD) and Ca(OH)2 + 2% chlorhexidine against E. faecalis. Eighty extracted single-rooted teeth were inoculated for 14 days and randomly assigned to four groups (n=20), with bacterial counts assessed before and after treatment. All experimental groups significantly reduced bacterial counts (P<0.05), with TAP showing the greatest reduction (95.74%), followed by Ca(OH)2 + CHX (93.86%) and OD (92.84%). Thus, TAP showed the highest antibacterial efficacy, while Ca(OH)2 + CHX and OD showed substantial activity against E. faecalis.
