چکیده    Objective: to evaluate the antimicrobial properties of several mouthwash concentrations on oral streptococcus mutans and escherichia coli. methods: the study was conducted at shiraz medicine school in 2011. serial dilutions of chlorohexidin, oral b and persica and irsha (2,4,8,16,64,128) were prepared in muller-hinton media. minimum inhibitory concentration was visually determined and defined as the lowest concentration of each oral washing which inhibited > 95% growth reduction compared to the growth control well. result: chlorhexidine, oral b and irsha mouthwash inhibited streptococcus mutans even with diluted concentrations. also, chlorhexidine and oral b prohibited escherichia coli with different potencies. but persica had no antimicrobial activity against either escherichia coli or streptococcus mutans. conclusion: chlorhexidine, irsha, and oral b mouthwashes can be used for antimicrobial effects, especially on streptococcus mutans. this chemical activity of mouthwashes is an adjuvant for mechanical removing of plaque. however, the antimicrobial effect of persicaremains controversial.
