OBJECTIVE: This study investigated the antibacterial action of 30% red propolis, 40% green propolis and 2.5% sodium hypochlorite with irrigation protocols in infected root canals.METHODS: During 60 days, twenty-four root canals were inoculated with E. faecalis. In all experimental groups were performed root canal preparation and two irrigation protocols - passive ultrasonic irrigation and conventional irrigation. In the groups 1, 3, 5 and 7 it were made root canal preparation associated to conventional irrigation with 30% propolis, 40% propolis, 2.5% sodium hypochlorite and distilled water, respectively. In groups 2, 4, 6 and 8 it was made root canal preparation associated with passive ultrasonic irrigation with the solutions described above. The groups 9 and 10 were the controls (negative and positive). Samples of the root canals were collected and immersed in 7 mL of BHI, for 48 hours, at 37ºC. Bacterial growth was analyzed by turbidity of the culture medium.RESULTS: Antibacterial action was observed of 30% red propolis and 2.5% sodium hypochlorite when used passive ultrasonic irrigation and conventional irrigation after 20 minutes, but in 72 hours it was not effective.CONCLUSION: The irrigating agents and protocols were not effective to eliminate the microorganisms of the infected root canals. Clinical Significance: Propolis presents potential for clinical application due to its antimicrobial, anti inflammatory, antioxidant and low toxicity properties.
