Abstract Objective:

To compare the antibacterial efficacy of Cuminum cyminum (cumin) extract and 2% chlorhexidine.

Material and Methods:

E. faecalis was isolated from non-vital teeth with chronic apical abscess. Samples were then bred in the ChromAgar medium. Subsequently, E. faecalis bacteria's DNA extraction was performed. DNA was then amplified by conventional PCR, and the product was run on an electrophoresis gel. Subsequently, we extracted Cuminumcyminum seeds using the steam distillation technique.

The extract was diluted at various concentrations:

0.2, 0.5, 0.7, 1.0, and 1.2 mg/mL.The extract's antibacterial effect was evaluated using an ELISA reader with optical density. Specifically, we assessed the turbidity of E.

faecalis in biofilms following immersion in antibacterial agents Results:

In the clinically isolated E. faecalis group, the OD values of 0.7 and 1.0 mg/mL cumin extracts were significantly different from that of 0.2 mg/mL cumin extract. A significant difference was also observed between the OD values of 1.0 mg/mL cumin extract and 2% CHX (p<0.05) Conclusion: The antibacterial effect of 1.0 mg/mL Cuminum cyminum extract had higher efficiency than 2% chlorhexidine against E. faecalis biofilms from clinical isolates.
