[Relationship between serum antibody to Bacteroides gingivalis and clinical parameters in periodontitis patients].
Prevalence and proportion of black-pigmented Bacteroides species (BPB) in supragingival and subgingival plaque were determined in ten adult periodontitis patients. Serum antibody against Bacteroides gingivalis (Bg) of these patients were tested using ELISA. Clinical parameters (PI, GI, PD, AL) were collected prior to blood withdrawn. Results showed that BPB were detected in all patients. Mean serum anti-Bg IgG level was significantly greater in the patient group than that in healthy control group. Although the sample size was too small to show statistical difference, there was a trend showing the sera anti-Bg IgG level tended to be greater in accordance with the increase of disease severity and BPB%.
