A Comparative Evaluation of Antibacterial Efficacy of Moringa oleifera Leaf Extract, Octenidine Dihydrochloride, and Sodium Hypochlorite as Intracanal Irrigants against Enterococcus faecalis: An In Vitro Study

Table 1

Enterococcus faecalis counts before (CFU-1/ml) and after (CFU-2/ml) application of the irrigants.

Irrigants	CFU-1/ml before irrigation (mean ± SD)	CFU-2/ml after irrigation (mean ± SD)	P-value
