[Relationship between clinical findings and subgingival microbial flora in periodontitis (2)].
The purpose of this study was to examine the relationship between clinical findings and subgingival relationship between clinical findings and subgingival microbial flora in periodontitis at the first medical examination and after initial preparation. The results obtained were as follows: 1. Clinical findings with the exception of plaque index showed improvement after initial preparation in comparison with the first medical examination. 2. In phase contrast microscopy, both total bacteria and incidence of spirochetes and motile rods decreased after initial preparation in comparison with the first medical examination. 3. Clinical findings with the exception of plaque index were related to the total bacteria and proportional distribution of spirochetes and motile rods in periodontal pockets, observed in phase contrast microscopy. 4. Total bacteria and proportional distribution of black-pigmented Bacteroides in periodontal pockets decreased after initial preparation in comparison with the first medical examination.
