Objetive: Evaluate the antibacterial effect of reciprocating systems associated with sodium hypochlorite 2.5% and apple vinegar in infected root canals. Methods: Fifty human anterior teeth uniradicular were prepared, inoculated with E. faecalis and examined after sixty days. The teeth were randomly assigned to five groups: (1. WaveOne® 40.08; 2. Reciproc® 40.06; 3. Unicorne® 40.06; 4 and 5 positive and negative controls. For each experimental group (n = 10), five specimens were irrigated with sodium hypochlorite 2.5%, and five with apple vinegar. Bacterial growth was analyzed using turbidity of culture medium followed by UV spectrophotometry. The cleaning of dentinal walls was analyzed by scanning electronic microscopy (SEM). Results: All groups showed a significant reduction of the optimal density of the culture medium after the root canal preparation (p<0,05). No sanitizing strategy promoted the complete elimination of E. faecalis. In the analysis of cleaning the root surface, it was found that in none of the groups showed complete removal of debris, not being verified significant differences indifferent to analyzed thirds (p> 0.05). Conclusion: The reciprocating instruments (WaveOne®, Reciproc® and Unicorne®) and irrigating sodium hypochlorite solution 2.5% and apple cider vinegar have not been effective in eliminating E. faecalis complete in infected root canals.
