Objective: The objective of the present work went verify, in vitro, the effect antimicrobial of those solutions about two species bacterial associated with disease periodontal. Method: The dyes, besides clorexidine at 0.12 as group controls positive, and alcohol of cereals, used in prepare it of the dyes, as negative control, they were diluted in saline solution of 1:2 up to 1:128. Using the method of the diffusion in agar, the stumps of reference Porphyromonas gingivales ATCC 49417 and Prevotella melaninogenica ATCC 25845, was sowed in half BHI agar enriched with yeast extract (0,5%) and incubated anaerobically, to 37th C for 3 days. Results: The results demonstrated that Plantain and Sage possess action antibacterial on the two stumps in test, as well as the clorexidine. Even so the dye of Taheebo didn't interfere in the growth of P. gingivales, being sensitive only P. melaninogenica to this dye. The stumps came resistant to the alcohol of cereals. Conclusion: It is ended that the Plantain dyes and Sage present larger spectrum of performance antibiotics, when compared the dye of Taheebo, being not its effect influenced by the alcohol used in its production. |
