Aim of the study: To compare the antimicrobial efficacy of Chlorhexidine and MTAD against Enterococcus faecalis in dentinal tubules of human teeth. Materials and Method: Freshly extracted, single rooted tooth were immersed in 5.25% NaOCl to remove surface soft tissue and organic debris. The teeth were horizontally sectioned into coronal, middle and apical sections. The 5 mm middle segment was used for the study. The segments were placed in brain-heart infusion broth containing a culture of E.faecalis. The root specimens were randomly divided into 3 groups. To test for bacterial survival, dentinal shavings from within the canal were collected using round bur on a piece of sterile aluminium foil. The mean CFU/mg and standard deviation value were calculated. Results: The antibacterial property of MTAD against E. faecalis was superior compared to that of Chlorhexidine.
