Preparing and evaluating the anti-microbial effect of Allium jesdianum mouthwash on some of the most common oral microorganisms

Abstract

ABSTRACT Background: Due to the increasing resistance of bacteria to antibiotics and anti-bacterial compounds in plants, Allium jesdianum Boiss plant extract can be used in mouthwash compounds with its anti-microbial activity. Methods and Materials: The anti-bacterial and anti-fungal activity of A. jesdianum mouthwash was investigated on Streptococcus mutans, Streptococcus sanguis, S. salivarius and Candida albicans, and Candida tropicalis. To analyse the anti-microbial effect of this mouthwash, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by the broth microdilution method. Results: The average MIC and MBC of A. jesdianum mouthwash for S. mutans were 1.56 and 3.12 (mg/ml), respectively, for S. salivarius, 0.25 and 0.65 (mg/ml), and for S. sanguis, respectively, 0.25 and 0.65 (mg/ml). The highest MIC and MBC values were for S. mutans, and the MIC and MBC values were equal for S. sanguis and S. salivarius. Average MIC and MBC were determined as 2.41 and 4.16 (mg/ml) for C. albicans and 2.34 and 5.72 (mg/ml) for C. tropicalis, respectively. MIC values of mouthwash were higher for C. albicans and MBC values for C. tropicalis. Conclusion: Our results showed a promising anti-fungal-anti-bacterial effect of A. jesdianum extract. A. jesdianum extract may be used as an alternative to chemical mouthwashes.
