TL;DR: The purpose of the present investigation was to attempt to define communities using data from large numbers of plaque samples and different clustering and ordination techniques, which related strikingly to clinical measures of periodontal disease particularly pocket depth and bleeding on probing.

TL;DR: Clinical improvement post-SRP was accompanied by a modest change in theSubgingival microbiota, primarily a reduction in P. gingivalis, B. forsythus and T. denticola, suggesting potential targets for therapy and indicating that radical alterations in the subgingival bacteria may not be necessary or desirable in many patients.

TL;DR: The data suggest an etiologic role for B. forsythus, P. gingivalis, T. denticola and S. noxia in adult periodontitis.

TL;DR: The data suggest that the maintenance phase of therapy may be essential in consolidating clinical and microbiological improvements achieved as a result of initial therapy.

TL;DR: Few microbiological differences existed between treatment outcome groups using DNA probes to known species, the predominant cultivable microbiota of 33 subgingival samples from 14 refractory subjects was examined, and Prevotella nigrescens was significantly more prevalent in successfully treated subjects, while refracted subjects harbored a larger proportion of Streptococcus species, particularly S. constellatus.
