Resumen

This study aimed to evaluate the antimicrobial effect of 4% sodium hypochlorite and the essential oils of Eucalyptus globulus L. (Eucalyptus), Plantago major L. (Llanten), and Caesalpinia spinosa (Tara) on Enterococcus faecalis strains. The essential oils were extracted using water vapor, and bacterial strains were seeded in petri dishes containing blood agar. Filter paper discs were impregnated with 4% sodium hypochlorite and each essential oil, and the cultures were incubated at 37°C for 24 and 48 hours. The inhibition zones were measured, revealing that Llanten and Tara essential oils exhibited greater efficacy against Enterococcus faecalis compared to Eucalyptus oil and sodium hypochlorite. The results showed a significant difference in the activity of Llanten oil over time, while the other substances maintained stable activity. ANOVA confirmed the significant differences between the inhibitory solutions, highlighting the superior efficacy of Llanten and Tara essential oils. Overall, all tested essential oils demonstrated antibacterial activity, with Tara oil showing the greatest effect, followed by Llanten, Eucalyptus, and 4% sodium hypochlorite. © (2024), (University of Dicle).
