The presence of bacteria in the root canal induces chronic periapical disease. Therefore, one of the most important objectives of endodontic treatment is to eliminate all microorganisms from the root canals, using both irrigating solutions and intra-canal medication between sessions, especially in cases of endodontic retreatment, due to the presence of persistent bacteria that may resist various commonly used intra-canal medications. Enterococcus faecalis are the most frequently isolated bacteria from teeth with endodontic failure and the main contributors to persistent apical periodontitis. The objective of this study was to evaluate the inhibitory effect of 2% chlorhexidine gel and calcium hydroxide mixed with various vehicles (2% chlorhexidine solution, camphorated paramonochlorophenol, and saline solution) against Enterococcus faecalis, using the agar well diffusion method. Fifty Petri dishes with brain heart agar were prepared, with each dish containing 4 wells saturated with intra-canal medications. The samples were incubated at 37°C, and measurements of bacterial inhibition zones were recorded at 1, 7, and 15 days. The data were processed using the analysis of variance statistical test, concluding that 2% chlorhexidine gel has greater antibacterial efficacy than calcium hydroxide combined with various vehicles (2% chlorhexidine solution, camphorated paramonochlorophenol, and saline solution) after 1, 7, and 15 days against Enterococcus faecalis.
