The purpose of this study was to investigate infant oral mutans streptococci (MS) by feeding method and by the mother%26apos;s oral MS status. For this cross-sectional data collection, full-term infants at 4-6 weeks of age and their mothers were tested for oral MS using the Dentocult((R)) SM chairside test (Orion Diagnostica, Espoo, Finland). For the 104 mother-infant pairs (68 breastfed, 36 formula-fed), the two groups differed by mother%26apos;s race/ethnicity (p=0.006) but not by delivery mode, level of care at birth, or MS in the mothers or the infants. Thirty-one percent of mothers and 12% of infants were MS positive. Infant MS was not predicted by mother%26apos;s race/ethnicity, delivery mode, feeding method, or MS status. When stratified by feeding method, the mother%26apos;s MS status did significantly predict the infant%26apos;s MS status in the breastfed group (odds ratio=5.97; 95% confidence interval, 1.06-33.7; p=0.043). In conclusion, oral MS at %26gt;10(4) colony-forming units/mL were detected in 12% of the 4-6-week-old infants, and the effect of the mothers%26apos; oral MS status was modified by the feeding method. Future research is needed to clarify the modifiable perinatal and maternal risks associated with the development of the infant%26apos;s predentate oral microbial environment, before the introduction of the first tooth.
