Background: involved in caries pathogenesis is classified into four serotypes, namely serotypes c, e, f, and k. can be found in the plaque of children with early childhood caries (ECC). Aims: The aim of this study was to analyze the quantity of the antigens of serotype e and and its correlation with the salivary flow rate in ECC.
Materials and Methods: The antigen quantities of caries plaque samples and caries-free were determined using an enzyme-linked immunoassay with 450-nm optical density.
Results: There was a significant difference between the quantity of serotype e and antigens in each salivary flow rate category ( < 0.05). The relationship between the antigen quantity of serotype e and was = 0.624 ( > 0.05) for caries plaque samples and = 0.628 ( > 0.05) for caries-free samples.
Conclusion: the antigen quantities of serotype e and and the salivary flow rate might correlate to the pathogenesis of ECC.
