Abstract：
:A significant correlation was found between the number of mutans streptococci in saliva and the proportional distribution of these microorganisms in pooled plaque from the margins of all restorations. At high salivary numbers there was a tendency towards a higher porportion of mutans streptococci in plaque from the margins of separate restorations. At low and medium salivary numbers, plaque samples could, however, contain greater than 10 per cent mutans streptococci and even less than 1 per cent was found in plaque from margins of restorations at high salivary numbers. The reproducibility of the plaque sampling method was good. Plaque material collected on different occasions from the same margins did not vary significantly in terms of proportions of mutans streptococci. The numbers of mutants streptococci in plaque samples from different restorations of the same kind collected on the same occasion in the same mouth could, however, show a considerable variation. The observations made in this study, indicate that a low salivary number of mutans streptococci does not exclude a high proportion of these microorganisms in plaque from the margins of separate restorations. This has to be considered when efforts are made to reduce the risk of recurrent decay.
