Abstract
ABSTRACT
Background and objectives
Among the bacterial species which most often cause endodontic failure, Enterococcus faecalis is the most important. This study compared the antibacterial efficacy of tea tree oil with 3% sodium hypochlorite and 2% chlorhexidine as a root canal irrigant, against E. faecalis
Materials and Methods
Normal saline, tea tree oil, 3% sodium hypochlorite, 2% chlorhexidine and fresh stains of E. faecalis were used. Four round wells, 4 mm deep and 8 mm diameter, were punched using sterile cork borer in blood agar plates and divided into four groups: group A: normal saline (control), group B: 3% sodium hypochlorite, group C: 2% chlorhexidine and group D: tea tree oil. Agar well diffusion method was performed to compare the antibacterial efficacy of tea tree oil, 3% sodium hypochlorite and 2% chlorhexidine.
Results
The results were tabulated and statistically analyzed using analysis of variance (ANOVA). Tea tree oil showed comparable inhibition of bacterial growth with sodium hypochlorite and chlorhexidine. No zone of inhibition was shown by normal saline (control).
Interpretation and conclusion
Tea tree oil showed statistically significant antimicrobial activity against Enterococcus faecalis, which is very much similar to sodium hypochlorite and chlorhexidine.
Abbreviations
CHX: Chlorhexidine; E. faecalis: Enterococcus faecalis; NaOCl: Sodium hypochlorite.
