[The microbial status of the periodontal pocket].

Analysis of components helped reveal the true relationships between the counts of individual representatives of the bacterial association in the contents of 18 periodontal pouches. Though the authors did their best to select a group of patients with the periodontitis course as similar as possible, the multidimensional grouping method has demonstrated the heterogeneity of this group. Four types of periodontal pouches were distinguished, differing by their bacterial status; this probably requires a differentiated approach to its correction.
