Resumo
The objective of this study was to investigate the antibacterial effect of alcoholic extracts of
30% red propolis, 40% green propolis and 2.5% sodium hypochlorite in different irrigation
protocols in root canals infected Enterococcus faecalis. Twenty-four extracted teeth with one
root canal were selected, the prepared root canals and inoculated with E. faecalis for 60 days.
The teeth were randomly divided into eight experimental groups (n = 3) and 2 control groups
(n = 3). 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 was made ready root canal associated with conventional irrigation to 30% propolis, 40%
propolis, 2.5% sodium hypochlorite and distilled water, respectively. In groups 2, 4, 6 and 8
was performed root canal preparation associated with passive ultrasonic irrigation and
irrigated with the same solutions described above. In the groups 9 and 10 were the controls -
negative (root canals uncontaminated) and positive (root canals contaminated untreated).
Samples of root canals were collected and immersed in 7 mL of BHI for 48 hours, incubated at
37 °C. The bacterial growth was assessed by turbidity of the culture medium. The results
showed antibacterial effectiveness of the alcoholic extract of 30% red propolis and 2.5%
sodium hypochlorite when used conventional irrigation and passive irrigation, only after 20
minutes. The irrigation protocols and the substances tested were not effective to eliminate
bacterial dentin contamination with E. faecalis.
