Evaluation of anti-bacterial efficacy of ginger, resin gum, and nigella sativa irrigants against enterococcus faecalis: an in-vitro study

Abstract

Objectives : To evaluate the antibacterial efficacy of Ginger, Resin Gum, and Nigella Sativa, against Enterococcus faecalis.

Methods : Thirty-eight extracted single-rooted premolars were inoculated with E. faecalis (except the negative control) and incubated for 4 weeks. After instrumentation, samples were divided into four groups (n = 7) according to final irrigation: NaOCl + EDTA (Group A), Nigella sativa (B), Resin Gum (C), Ginger (D), plus two control groups (n = 5): Saline (E) and Saline without bacterial inoculation (F). Cultures were collected at baseline and after irrigation.

Results : One-way ANOVA showed that in groups A–D a statistically significant reduction of bacterial load was observed at T1 after final chemo-mechanical instrumentation (p < 0.05). The antibacterial reduction rate was as follows: Nigella sativa (99.89%), Ginger (99.85%), and Resin Gum (99.64%).

Conclusions : Herbal irrigants can be used as adjuncts to NaOCl in eradicating E. faecalis.
