Context: The usual cause of nonfulfillment of endodontic therapy is the persistence of microorganisms in the root canal system due to ineffective disinfection. Enterococcus faecalis is one of the most prevalently isolated microorganisms following a failure in root canal treatments. Sodium hypochlorite is among the most effectively used irrigant solutions but has many shortcomings. Herbal alternatives for sodium hypochlorite might prove to be superior due to their high antimicrobial activity, biocompatibility, and their antioxidant and anti-inflammatory properties. Aims: This study is aimed to evaluate the antimicrobial efficacy of Trachyspermum ammi oil and Elettaria cardamomum oil against 2-week-old and 4-week-old E. faecalis biofilms formed on tooth substrate. Settings and Design: A pure culture of E. faecalis was grown on brain heart infusion agar, inoculated into brain heart infusion broth, and incubated at 37°C overnight. Single rooted human mandibular premolars were sectioned below cementoenamel junction, enlarged, and vertically sectioned along the midsagittal plane. The samples were then placed in tissue culture wells inoculated with 2 ml of the bacterial solution and incubated at 37°C. Materials and Methods: Group 1 E. cardamomum oil (cardamom), Group 2 T. ammi oil (ajwain), Group 3 5% sodium hypochlorite, and Group 4 Saline (control) (n = 10). At the end of the 2nd and 4th weeks, all groups were treated for 10 min with 3 ml of the respective solutions. Quantitative analysis was performed by serial dilution. Results: T. ammi oil and sodium hypochlorite treated teeth showed complete elimination of both the 2-week-old and 4-week-old E. faecalis biofilm. Meanwhile, saline and E. cardamomum oil-treated teeth still showed the presence of E. faecalis. Conclusions: The use of T. ammi oil as a root canal irrigant solution can be considered as an alternative to sodium hypochlorite.
