--- The aim of this study was to determine the antibacterial activity of the extract of coca leaves (Erythroxylum coca), on Black Pigmented Bacteria (BNP). Those periodontopathogenic bacterias are Gram negative and strict anaerobic, also they are strongly related with the progression of periodontitis. To this purpose, the study used two different kinds of tests; the first, Agar Diffusion Test; and the second, Dilution Test in Liquid Medium. BNP strains were isolated from samples taken from periodontal pockets (greater than 4 mm) of patients with periodontal disease treated at the Faculty of Dentistry of San Marcos University. The coca leaf extract was obtained from the National Coca Company (ENACO). The results of the first study indicated that the extract of Erythroxylum coca has zero sensitivity (-) for most of the tested concentrations, and sensitivity limit (sensitivity: +) to the concentration of 12,5 % and 100 %. The results of the second study determined a minimum concentration of extract able to inhibit the growth of said bacterium; this value was 100% (CMI) Also, concentrations of 12,5 % and 6,25 %, both indicated repowering of the antibacterial effect of the extract. Therefore it is concluded that, the extract of coca leaf has an antibacterial activity against BNP, in concentrations of 100% and 12, 5%. KEY WORDS: Extract, coca, antibacterial, anaerobic bacteria.
