An in vitro evaluation of the antimicrobial efficacy of Curcuma longa, Tachyspermum ammi, chlorhexidine gluconate, and calcium hydroxide on Enterococcus faecalis.

This in vitro study was designed to comparatively evaluate the antimicrobial efficacy of Curcuma longa (turmeric - T1-10%, T2-20%); Tachyspermum ammi (ajwain - A1-10%, A2-20%); chlorhexidine (CHX) gluconate gel (hexigel - 1%); and calcium hydroxide (10%) as intracanal medicaments against Enterococcus faecalis. Agar plates were prepared using brain-heart infusion (BHI) agar. Cultures of E. faecalis were grown in BHI broth at 37°C. Well diffusion method was used to derive results. Plates were inoculated for 72 h at 37°C and microbial zones of inhibition were recorded. Statistical analysis was performed with repeated measures analysis of variance. C. longa (T2-20%) and CHX gluconate gel (hexigel - CHX-1%) showed larger zones of microbial inhibition than C. longa (T1-10%) that were statistically significant (P < 0.05) and were highly significant when compared to T. ammi (ajwain - A1 and A2) and calcium hydroxide. C. longa can be used as intracanal medicament in endodontic failure cases.
