The aim of the research is a comparative study and contrasting of pathogenic bacterial composition in periodontal pockets and amniotic fluid in new mothers with normal and premature delivery terms.48 women with periodontal diseases underwent clinical and microbiological tests. 28 of the women gave premature births; and the rest 20, term births. The studies showed that the presence of severe periodontium inflammation, especially with a profound destructive pathological component (with the 4-score depth of periodontal pockets and tooth mobility), must be admitted as a risk factor for occurrence of premature delivery. This statement is even truer in cases of detection of prevotella bivia in relatively big amounts (in particular in Armenian population). In its turn, the findings presented above increase the diagnostic significance of microbiological testing of periodontal pocket content in relation to forecasting pregnancy outcome.
Key words: periodontal disease, periodontal pathogens, prevotella bivia, risk factors, premature delivery.
