Streptococcus mutans is considered among the most important microbes that cause dental caries on its own and in its presence in association with types of Streptococcus bacteria, such as Streptococcus sobrinus, with which it produces acids that provide an acidic environment in the oral cavity and teeth. In our study (100 specimens) of dental caries were collected by swap into transport media (invasive sterile collection), from patients that they visit the Educational Clinics of the Dentistry Collage/ University of Babylon, during (April-2022). And they cultured by using modified (Mitis Salivarius Agar Base) (MSAB), with addition of bacitracin antibiotic and sucrose, the results were 36 positive samples, and 64 negative samples.
