Introduction : Candida albicans has been isolated in up to 65% of healthy individuals without signs of clinical disease. Mouthwashes can be used for many preventative and therapeutic purposes. This study evaluates the effectiveness of Iranian and foreign mouthwashes against C.albicans as a common fungal flora in the mouth.   Materials and method s: In this research, standard strain of C.albicans, ATCC 10231 is used. The suspension is provided by a fresh culture of C.albicans (24 hours) and the OD is read in 530 nm. The C. albicans suspension was cultured on Sabouraud dextrose agar plate. In the next step, two wells created on SDA, filling with mouthwashes (100 µl). After incubation at 37ºC for 24 hours, the inhibition zone was measured. Minimum inhibitory concentration (MIC) and Minimum fungicidal concentration (MFC) of mouthwashes were determined. The data are analyzed by SPSS software, independent T-tests and one sided variance analysis (ANOVA-one way).   Results : Findings of our study showed in which agar diffusion, MIC and MFC tests, there are no significant differences between the antifungal effect of the Iranian and foreign mouthwashes on C.albicans (P value>0.05 ).   Discussion and conclusion : This study shows that both Iranian and foreign mouthwashes have a good effect against C.albicans, as a common fungal flora in the mouth.
