Relation of periodontal pathogens in placenta with low birth weight babies
Aim: To evaluate the possible correlation between periodontal pathogens in placenta with low birth weight babies.Materials and Method: The study included 30 pregnant females distributed equally into study (delivered preterm low birth weight babies) and control group (delivered at normal term with normal weight babies). At the time of delivery, sample of placental extract was collected. Within two days postpartum clinical periodontal parameters of mothers i.e. subgingival plaque and calculus sample was collected. Placental extract and subgingival plaque and calculus samples were subjected to anaerobic culture, and various microorganisms present were identified. Results: A significant difference (p<0.05) was found between no. of weeks of pregnancy, weight of baby at birth, no. of teeth with probing depth (PD) ≥4mm, no. of teeth with clinical attachment loss (CAL) ≥4mm, percentage (%) of sites with bleeding on probing (BOP), between study and control groups. Conclusion: Positive correlation was seen between placental and plaque microorganisms in preterm group, indicating periodontitis to be a potential risk factor for preterm low birth weight babies.
