“…The detection frequency of mutans streptococci on occlusal surfaces did not increase as teadily as the detection frequency for buccal, approxitnal and lingual surfaces with increasing salivary concentrations. In sotne other studies the occlusal surfaces have shown higher (10,26) or similar (4,27) isolation frequencies when compared with other surfaces. One possible reason for the lower detection frequency of tnutans streptococci on occlusal surfaces at higher salivary numbers in the present study might be that our population consisted mainly of adults who had most of their occlusal surfaces restored.…”

The relationship between the salivary concentration of mutans streptococci and their prevalence on different tooth surfaces was studied in 114 subjects. Plaque samples were obtained from all tooth surfaces in the dentition and the infection magnitude of mutans streptococci was determined. The salivary concentrations of mutans streptococci correlated significantly with the number of colonized tooth surfaces and with the infection level of mutans streptococci for individual teeth or groups of tooth surfaces. The highest correlation values were found for buccal and approximal surfaces and for molars followed by premolars and anterior teeth. The 10 tooth surfaces best reflecting the salivary levels of mutans streptococci were 5 buccal and 5 approximal sites, 6 of them localized on maxillary posterior teeth. A significant positive relationship was noted between the prevalence of mutans streptococci in saliva and on the dorsum of the tongue.

“…In the first study, because of the coinci dent occurrence of S. mutans and caries on occlusal surfaces [Street et at., 1976). it was of particular interest in this study to find a single serotype (type c) predominating un der these conditions (table IV).…”

“…This study placed emphasis on the sampling of specific sites, since the prevalence of S. mutans seems influ enced markedly by the sites examined [Ikeda and Sandham, 1971;Hoerman et al, 1972;Shklair ei al., 1972;Street et al, 1976]. Further, variations observed in the decay attack rates of tooth surfaces within the developing dentition [G/asi et al, 1970;Berman and Slack, 1973;Finn, 1973] may be more readily comprehended if individual serotypes displayed significant preferences in their colonization behavior.…”

The frequency of five Streptococcus mutans serotypes (a, b, c, d and e) was investigated in relation to tooth surface and its caries status in young schoolchildren. In the first study, plaque from the five surfaces of a second deciduous molar in 104 five-year-olds was examined for the presence of S. mutans. In the second study, isolations were made from the occlusals and approximal surfaces of a second deciduous and a first permanent molar in five- to eight-year-olds. The isolates were characterized biochemically, and then serotyped with antigen extracts against whole cell and ‘purified’ cell wall antisera using comparative immunoelectrophoresis. Of the 348 plaque isolates, type c was the prevalent serotype (91.1%). In the first study, a significant relation was found between the occurrence of type c and caries on the occlusal surfaces. However, the second study showed type c to be evenly distributed on the occlusals and approximal surfaces irrespective of caries status. This leaves open the possibility that certain types may be commensals.

“…Epidemiological surveys have indicated that S. mutans can nearly always be isolated from carious lesions, and its proportions in plaque from carious teeth are generally higher than those from sound teeth (19,24). Furthermore, subjects highly infected with S. mutans develop more caries than those with a low level of this organism (15,16,20).…”

“…Streptococcus mutans has been considered to be the most important microorganism involved in the occurrence of dental caries in experimental animals as well as in humans (10). Epidemiological surveys have indicated that S. mutans can nearly always be isolated from carious lesions, and its proportions in plaque from carious teeth are generally higher than those from sound teeth (19,24). Furthermore, subjects highly infected with S. mutans develop more caries than those with a low level of this organism (15,16,20).…”

Thirty-four female rats (18 days old) were infected with Streptococcus mutans MT8148R (serotype c) or 6715 (g). Diets containing different proportions of sucrose were used to prepare the dams which harbored various levels of S.mutans in their oral cavity. Around 66 days of age, the female rats were bred and 34 dams subsequently bore 322 offspring. The dams were killed upon weaning (20 days of age) of their respective litters. There were positive correlations between the recovery of inoculated S. mutans and the caries incidence in the dams. Transmission of S. mutans from a dam to her offspring was studied in 10-, 15-, 20-, 27-, 34-, 41-, 48-, and 55-day-old rats by evaluating the recover of S. mutans from the offspring. Positive correlation between the magnitudes of recovered S. mutans MT8148R from dams and their offspring was found in all ages of young rats examined. Furthermore, caries incidence in young rats was found to be positively correlated with the recovery of both strains of S. mutans as well as with incidence of caries in their respective dams.
