ABSTRACT

Objective To investigate the relationship between the bacterial vaginosis and 8 putative periodontal pathogen infection.Methods A total of 48 patients with bacterial vaginosis were collected and 47 healthy female patients were selectedin the control group.Vaginal secretion and subgingival plaque were obtained from the study group and the control group.The presence of Porphyromonasgingivalis (P.g),Tannerella forsythia (T.f),Treponemas denticola (T.d),Prevotell intermedia (P.i),Prevotella nigrescen (P.n),Peptostreptococcus micros (P.m),Fusobacteriumnucleatum (F.n) and Campylobacterrectas (C.r) was detected by DNA extraction and PCR method.Simultaneously,all the patients underwent a clinical periodontal examination of the teeth in community periodontal index,including plaque index (PLI),bleeding on probing (BOP),probing depth (PD) and clinical attachment loss (CAL) Results The prevalence of periodontal disease,PLI,BOP and CAL in the study group was significantly higher than in the control group (P＜0.05) and the PD had no statistically significant difference between the 2 groups (P＞O.05).The 2 groups were both detected 8 putative periodontal pathogens in the vaginal secretion and the subgingival plaque samples.The detection ratio of T.dfrom both the vaginal secretion and subgingival plaque samples was significantly higher in the study group than that in the control group (P ＜0.05),and other 7 pathogens showed no statistically significant difference (P ＞0.05) Conclusion The prevalence of periodontal disease was higher among the bacterial vaginosis patients.The 8 putative periodontal pathogens were normal flora in the subgingival plaque and vaginal secretion.Td might be relevant to the pathogenesis of bacterial vaginosis.
