Objectives: To compare the effectiveness of different irrigating solutions in eliminating of Enterococcus faecalis in patients with chronic periapical pathology by applying microbiological tests. Methods: Twenty one teeth with chronic apical periodontitis of non suppurative diagnosis of patients that attended the dental clinics of the University of Cartagena were evaluated after the patients signed the consent form to participate in the study. The study subjects were randomized into three groups using the following irrigating substances: Sodium hypochlorite at 5%, chlorhexidine 2% and sodium hypochlorite and MTAD. Microorganisms were identified through the Chain Reaction (PCR) and quantified the colony forming units before and after Enteroccocus faecalis be used irrigating substances for cleansing. Statistical analysis: We performed the Kruskal Wallis test. Results: The research showed that all substances were effective in eliminating E. faecalis in patients with chronic apical periodontitis non suppurative. Sodium hypochlorite 5% (p= 0,018), sodium hypochlorite and MTAD (p= 0,021) and chlorhexidine 2% (p= 0,028) were equally effective. Conclusions: Sodium hypochlorite 5% chlorhexidine 2% and sodium hypochlorite and MTAD can be used in patients with chronic apical periodontitis non suppurative after being proven effective in eliminating E. faecalis.

Keywords : Periapical periodontitis; sodium hypochlorite; chlorhexidine; Enterococcus faecalis.
