[The study of major anaerobic bacteria from subgingival plaques of juvenile periodontitis].
The studies of the subgingival plaques from juvenile periodontitis (JP) have shown that JP is associated with Haemophilus actinomycetemcomitans (H. a), Capnocytophaga (Capno.) and other species. This study was designed to study these species with Chinese JP patients using selective cultivable technique. The media used include TSBV to support H. a, TBBP to support Capno. and selective media for Bacteroides gingivalis. A total of 303 subgingival samples were collected from 43 JP, 31 gingivitis and 13 normal juvenile. It was found that the recovery rates of H. a and Capnocytophaga in JP group were higher than that in two other groups. The Black-pigmented Bacteroides had a similar recovery rate in JP and gingivitis groups, but higher than that in periodontal healthy group. The bacterial counts and the correlation analysis between bacteria findings and clinical indices were consistent with the above results.
