Objective: inconclusive evidence exists regarding potential cariogenicity of milk formulas compared to breast milk.The study aimed compare Salivary Streptococcus mutans (S. mutans) and lactobacilli detection counts amongbreastfed (B), plain formula (France Lait 1) (FL) probiotic supplemented (Nan 1 optipro) (N) infantsand assess in-vitro growth these bacteria in samples. Material Methods:salivary samples were obtained using sterile cotton swabs from 60 infants that grouped according nursingmilk type. Samples cultured obtain the frequency bacterial counts. For investigation,seven donated seven freshly prepared both inoculated byboth then growth. Results: detected all infants, whileno significant differences found S. among groups. Counts microorganisms insaliva lowest (B) while, insignificant difference was between (N). Significant differenceswere evident being followed by (FL). Conclusion: andprobiotic supplement infants’ may have a protective role against dental caries infants.KEYWORDSBreast milk; Lactobacilli; Milk formula; Probiotics; Streptoccus mutans.
