“…Actually, S. mutans could form more than 50% of the total flora. Such high proportions have been reported earlier with cultural techniques (1,4,5,7,11,13,15,17,18,20,23,24). In this study, however, we used an immunofluorescent/phase contrast technique which excludes the possibility that the high numbers of S. mutans were an effect of selective growth only.…”

Abstract— Plaque samples from 10 different tooth surfaces of 10 schoolchildren with Varied Caries experience (DFS 10‐33) were collected five times during 2.5 years. The samples were examined with an immunofluorescent technique for identification and enemeration of Sreptococcus mutans scrotypes C/e/f and d/g. At each sampling occasion the children were scored for caries. A Stimulated saliva sample was also collected and the number of S. mutans per ml salva was determined. The salva level of S. Mutans was Shown to reflect the prevalence and proportion of this microorganism on theselected surfaces. Five surfaces carried S. nutans at each sampling. Four of these surfaces showed progressive caries. S. mutans infection was also found to precede the development of incipient caries on four surfaces. Eighty percent of the surfaces that stayed sound were only transiently carrriers of S. mutans in mainly very low numbers. Serotype c/e/f dominated in prevalence and proportion on the surfaces with a history of caries during the study.

“…The importance of Streptoeoeeus mutatis in the initiation of dental decay has been studied extensively (42), Since mutans streptococci and lactobacilli have been itnplicated directly in the initiation and progression of dental caries, these organistns have been associated with caries risk assessment in a number of studies (22,25,37,42,54), The associations of mutans streptococci and lactobacilli to the prevalence of dental caries have been studied extensively throughout the world (I, 3,4,7,13,14,30,31,33,34,53,56,63) but relatively few studies have addressed the problem in North America (8,11,26,32,43,59) and none has addressed the issue of water fluoridation.…”

Plaque indices, numbers of mutans streptococci, lactobacilli and total viable flora in plaque and saliva were assessed as part of a large-scale cross-sectional study designed to determine the factors that are associated with high caries activity in children. Subjects, 12 to 15 years old, residing in areas where the water supplies were either fluoridated (n = 140) or fluoride-deficient (n = 173) were studied. Mutans streptococci and lactobacilli numbers in saliva were positively correlated with plaque index. Plaque indices were significantly higher in the high-caries group than in the zero-caries group of the fluoride-deficient community. In the fluoridated community, there was no difference in the plaque index between the zero- or high-caries groups. In each community, pooled dental plaque and saliva harbored fewer mutans streptococci and lactobacilli in the zero-caries than the high-caries group. Greater numbers of mutans streptococci were found in the dental plaque and saliva of the zero-caries subjects in the fluoridated community than in the fluoride-deficient community, suggesting that a greater caries challenge can coexist with zero-caries status in the fluoridated community.

“…This group of organisms has been separated into 6 distinct species (1,9,10) among which Streptococcus mutatis and Streptococcus sobrinus are the most commonly demonstrated in human populations (3,18,34). The mutans streptococci are widely distributed not only in populations with rnoderate or high caries prevalence (2,26,32,35,39,40) but also in populations having no or low caries experience (4,5,22,31,36). The abundance of mutans streptococci in populations with low dental caries prevalence (5,6,12) is somewhat surprising since factors selecting for these organisms are also promoting the development of caries (20,28).…”

Strains of mutans streptococci isolated in a population with extremely low caries prevalence are cariogenic in the hamster model

Strains of Streptococcus mutans and Streptococcus sobrinus freshly isolated from a population almost free of caries were examined in hamsters maintained on a high sucrose diet. The strains were readily implanted and persisted in high numbers during the experimental period. The test strains all induced caries, with caries scores equal to or higher than those of a reference strain of S. mutans. The results indicate that the strains have inherent cariogenic properties which are revealed under a frequent exposure to high concentrations of sucrose in the diet.
