| Popis: | Aim: To evaluate in vitro , the antimicrobial effect of Cymbopogon citrates (lemon grass), Plectranthusamboinicus (Mexican mint) and Conyzabonariensis (hairy fleabane) tinctures as well as pure and diluted commercial mouth washes (Malvatricin ® , Periogard ® and Listerine ® ) on wild isolates of Streptococcusmutans and reference strains of S. mutans , Streptococcus salivarius, Streptococcus oralis and Lactobacillus casei by determination of minimum inhibitory dilution (MID). Materials and Methods: 0.12% chlorhexidine and 70% corn alcohol were used as positive and negative controls, respectively. Saliva samples were collected from 3 volunteers and seeded in MSB broth to obtain Streptococcus isolates after 72-hour incubation. Using the agar diffusion method, susceptibility tests were performed with overnight incubation in microaerophilia at 37°C. All tests were performed in duplicate. Results: The bacterial species were resistant to the tinctures and Listerine ® , but were susceptible to 0.12% chlorhexidine, Malvatricin ® and Periogard ® , with MIDs ranging from 12.5% to 1.56%. Conclusions: Plectrantusamboinicus, Conyzabonariensis and Cymbopongoncitratus tinctures and Listerine ® did not show inhibitory action against the tested biofilm-forming bacteria. |
