Phytotherapy applied to Dentistry is presented as an effective alternative treatment against periodontal diseases (PD) because it seeks to use the active ingredients of medicinal plants that are found in large quantities in nature, thus giving it the characteristics of being more affordable. and at a lower cost, to combat the pathogenic microorganisms that cause PE. Objective: to determine the in vitro antibacterial effect of the ethanolic extract of Equisetum giganteum L. against ATCC strains of Fusobacterium nucleatum. Material and methods: The study was of a non-probabilistic experimental type and consisted of a total of 10 Petri dishes seeded with F. nucleatum. Ethanolic extract of E. giganteum L. was used in concentrations of 100, 50, 25, 12.5 and 6.25 %. The agar diffusion method was used and 10 plates were incubated at 37 °C for 07 days. The inhibition halos were measured with a digital vernier, and these data were subsequently analyzed. Results: No significant inhibition halos were found in any of the embedded disks with the different concentrations in the 10 Petri dishes seeded with F. nucleatum, but without chlorhexidine, the chemical agent used as a positive control. Conclusions: an in vitro antibacterial effect of the ethanolic extract of E. giganteum L. was not determined against F. nucleatum, in any of its concentrations.

KEY WORDS: periodontal diseases, Equisetum, Fusobacterium nucleatum, antibacterial, plant extract.
