“…Although a stability in recovery of the satne species in each subject was found, the telative proportions of S, mutans and S, sobrinus when found together changed with titne. These fiuctuations tnight be the result of changes in sucrose consutnption, A few anitnal studies have indicated that itnplantation of S, .sobrinus is favoured by high sucrose consumption (11,27), which is in agieetnent with the observation of an enhanced attachtnent of S, sobrinus in the presence of sucrose (7), This hypothesis is given sotne support by the observation in this study that tnore children who carried both S, mutans and S, sobrinus had a higher nutnber of total tnutans streptococci and also a tendency to higher caries ptevalence than childten who carried only 5, tnutctns, Sitnilar obsetvations have been made in other populations (19,26),…”

Seventy‐eight 4‐year‐old children, examined earlier for the presence of mutans streptococci at 4‐month intervals from 15 months of age, were recalled for recording of dental caries and salivary sampling. The saliva samples were analysed for the presence of mutans streptococci, including the species Streptococcus mutans and Streptococcus sobrinus and lactobacilli. The results showed that the earlier the mutans streptococci had been detected in the children, the higher the caries experience. Eighty‐nine percent of the children colonized at 2 years of age had experienced caries and had a mean dfs of 5.0 compared with 25% of the non‐colonized 4‐year‐olds with a mean dfs of 0.3. S. mutans was the predominant species. S. sobrinus was usually found in combination with S. mutans, except in 2 children where S. sobrinus was the only species detected. More children with multiple species had higher numbers of total mutans streptococci and a tendency to higher caries prevalence than children with only S. mutans.

“…mutans (109,343). This is because the attachment of S. mutans to the AEP is mediated by an adhesin(s) which interacts directly with salivary components, whereas S. sobrinus lacks this adhesin (109).…”
