The efficacy of passion fruit juice as an endodontic irrigant compared with sodium hypochlorite solution: an in vitro study.
OBJECTIVE
To assess the effectiveness of several concentrations of two forms of passion fruit juice (PFJ) in the elimination of Enterococcus faecalis and to compare the antibacterial property of PFJ with sodium hypochlorite (NaOCl) as an intracanal irrigant.


METHODS
Two types of PFJs, aqueous and alcohol extracts, were prepared and a minimum inhibitory concentration (MIC) test was performed with both the extracts against E. faecalis. Two concentrations of each extract were selected from the results given by the MIC test and subjected to a broth dilution test (BDT) for nine different time periods. After each time period, samples were inoculated in brain-heart infusion agar plates for 24 h at 37°C and results were compared statistically.


RESULTS
The MIC test showed that E. faecalis was sensitive to PFJ extracts at various concentrations. The results of the BDT showed a negative growth of E. faecalis by PFJ alcohol 20% at 30 min, PFJ aqueous 20% at 1 h, NaOCl 2.5% at 10 min and NaOCl 5.25% at 1 min. NaOCl showed a much better antibacterial efficacy than PFJ.


CONCLUSIONS
The PFJ alcoholic and aqueous extracts had an antibacterial effect against E. faecalis. As PFJ shows promising results, further research in this field could lead to much better results as compared to NaOCl.
