Abstract
Nigella sativa (kalonji) has been used since ancient times as a nutritional supplement and for treating various infections and chronic ailments. As pathogens become resistant to most drugs, kalonji can be used as an alternative compound in modern medicines. The use of herbal extracts as endodontic irrigants might be beneficial as a part of a growing trend to seek natural remedies for dental treatment.
Aim: To compare the antibacterial potency of Aqueous Nigella sativa extract, Aqueous Neem leaf extract, and 3% Sodium Hypochlorite.
Materials and Methods: Test solutions were tested against E. faecalis (ATCC 29212) to check for their Minimum Inhibitory Concentration (MIC) by double dilution method and Kill time to measure their antimicrobial potency to be used as an intracanal irrigant.
Results: The study's limitations show that Aqueous Nigella sativa extract has a better antimicrobial effect than Aqueous Neem leaf extract and 3% Sodium Hypochlorite solution against E. faecalis.
Keywords: Herbal irrigants, nigella sativa, sodium hypochlorite
