The presence of the caries germ Streptococcus mutans in oral cavity of the pregnant woman is an important prognostic factor for the dental health of the child. Control of the Streptococcus mutans amounts of the mother and the resulting preventive measures in the dental practice are therefore an important factor for the future dental health of the child. High mother mutans amounts often mean early detectable Streptococcus mutans in toddlers. This represents a high risk of caries and can lead to early childhood caries (ECC).

The detection of Streptococus mutans in pregnant women is an efficient method to indicate the risk of MS being transmitted from the mother to the child. The detection of SM in the child influences the risk of caries.
