  Background: The aim of this study was to evaluate the association between dental caries and concomitant infections of Streptococcus mutans (S. mutans) and Streptococcus sobrinus (S. sobrinus) according to the ratio of cariogenic bacteria in plaque samples from adults to obtain basic data to develop clinical and chairside culture assay (kits) for assessment of dental caries risk. Methods and Materials: Plaque samples from 192 adult volunteers (age range, 20-28 years) were obtained using sterile toothbrushes. Caries history and the number of decayed, missing, and filled (DMF) teeth were determined. Subjects were divided into high- and low-risk groups according to the ratio of S. mutans to total streptococci (Sm/TS ratio) and the number of S. mutans. Results: The numbers of S. mutans and S. sobrinus and the Sm/TS rati.. View More»
