| epidemiological survey of streptococcus mutans in a group of adult patients living in pisa (italy). | an epidemiological investigation was carried out to evaluate the prevalence of streptococcus mutans in a group of 134 adult patients. markedly higher frequency of isolation was observed in caries-active subjects than in caries-inactive or caries-free subjects, indicating a significant association between the prevalence of the microorganism and the caries status. moreover, the presence of the microorganism appeared to have a significant association with the extent of caries experience evaluated b ... | 1992 | 1644142 |
| prevalence of streptococcus mutans and dental decay in school children from siena (italy). | epidemiological indexes of dental decay and prevalence of streptococcus mutans in dental plaque were studied in a group of 255 schoolchildren aged 6-11 from a suburban area near siena (italy). mutans streptococci were isolated from 17.4% of subjects: a significant correlation with dental decay indexes and with the presence of active caries was observed. | 1989 | 2767227 |
| first characterization in italy of clinical isolates of mutans streptococci by using specific monoclonal antibodies. | the aim of this investigation was to gain further insight into the prevalence of different serotypes of mutans streptococci in the italian population by using specific monoclonal antibodies in an enzyme immunoassay. isolates from dental plaque samples, collected from an adult population living in pisa (italy), were identified as mutans streptococci on the basis of their morphological and biochemical properties, and were then serotyped. the results show that 77.5% of the strains isolated belonged ... | 1993 | 8307132 |
